Loving the Jaaag. I'll be in the market for something similar to do some road trips in next year. As you say, you expect a few niggles with a cheap old luxury car so it's good to see what you get for your money
Lovely car but as with many of your vehicles, it’s a shame you have to spend so much on labour! You could save a fortune if you could collaborate with a good tech!
Hello Joel. I am a former Jaguar technician. As one other commentator on here has suggested a simple pressure test will usually reveal the issue, unless it's something like a head gasket that has gone which is very unlikely. One thing that is often overlooked and could quite easily be the cause of your issues is the actual expansion tank cap! They perish and at 20 years old it could easily be this if the rubber seal has expired. Well worth a try, but pressure check first. You can be pretty confident it won't be oil that is leaking as you would know by the smell of burning oil in that area near the exhaust manifolds and it burns blue so pretty easy to identify. Car is well worth saving as they are becoming quite rare and yours looks in good shape from what I can see. The Jag V8 engine is a gem, just change oil and filter regularly especially if it stands for long periods. Russ
The reason the coolant is lost after the car warms up is that initially, the coolant does not circulate until the engine is up to temperature. Also, I think you can save a lot of money by sourcing used parts or checking online yourself. You can get a new expansion tank on ebay for £35!
Yeah not sure why he's letting the garage source the parts when he can certainly get them himself and rather pay the labour to get it fitted, a lot cheaper
If you only wind up being ~ €2000-2200ish into the Jag and have it sorted, that'll truly be a great deal. Even if it needs more (let's be honest, it probably will 😅) it's still a fantastic car for the money!
I have a 1998 XK8. The heater hoses under the intake manifold and the octopus hose behind the engine can leak once the thermostat is on. When the temp is still low, the thermostat is shut and coolant would not flow in those hoses.
Looking at where the leak is coming from it could very possibly be the heater valve assembly. It's very common (been there). I have the 3L V6 and the 4.2V8 and they're both great cars. If you should fancy straight piping it I have a set of bespoke rear pipes you can have.
Enjoying the Jag content. As others have said, it's a 20+ year old Jag, it will need a regular dollap of cash and constant fettling but a good opportunty to learn to tackle a few basic jobs yourself and it will keep going for many miles.
Joel, my guess is that this is a split hose after the thermostat. Once the engine warms up the thermostat will open allowing coolant to circulate through the radiator so I’m guessing that the car is unaffected by the split right up until the thermostat opens.
Really good video Joel - but a big bill for such a simple item! Replacing a coolant tank would take me around 30 minutes (including a cup of tea) and a spark plug/coil about the same on my XK8. If you shop around parts are not expensive for these cars and even modules can be rebuilt now. The forums are a great source of knowledge and very helpful. It's been years since I have let a 'technician' anyway near mine - any despite what some may tell you - the engineering on these cars matches or exceeds anything you can find in Germany.
Driving my x type 2.5 2002 back home one day I saw the “smoke” and smelled coolant burning in the ac. Started overheating pulled over opened the hood and was burned from spraying coolant lol. It was some hard plastic pipe that cracked which we ended up j&b plastic welding shut again and it was fine. At that point we were tired of putting money into it so yea. Plastic weld was perfect at the time hahah.
Good to see your looking after the old girl Joel! Love cars like old jags they dont make them like they used to! fingers crossed its not too spenny to fix !
I personally would remove the tax disc and parking permit but keep them in the owners handbook folder. Same for the other stickers if you think you can remove them without damaging them or the glass. I would also keep the old reg plates if they are the originals.
I have had a similar experience on my X-type where the water pump was worn out, soon after it was the radiator and last of all, a leak off a pipe that was connected to the radiator. in between time, if you HEAR a gurgling sound then you KNOW the coolant level is going down, so check the header Tank level straight away and look for any leeks. thanks
My 2006 S Type is doing exactly the self and same thing, the difference is mine is a 2.7 twin turbo diesel V6 automatic, and you are right in part, it is a pipe that has split, but if its the same pipe as mine it's buried at the back of the engine and has to be dropped out of the car, if you still have the original radiator overflow bottle check it thoroughly as chances are it's not damaged, hope this helps.
I still have my 1997 VW Golf GTI VR6 that I’ve owned since new. It has 229k miles so far, and has now become my sunny day car. Anyway, it went through a period of coolant leak issues and dumped its guts twice. Eventually had to have all the hoses replaced and a new radiator as well! I feel your pain Joel!
Joel! I believe I may have the exact same issue as you on my 3.0 x-type. Except I think mine is just in the very early phases as I can do a good 100 miles before having to top up the coolant again. It’s definitely not head gasket, and I can’t really spot any leaks, I’ve just replaced the cap which kept sticking so if it isn’t that it must be the tank or pipes because the radiator seems to be fine.
I hope that Dell Motor Services takes responsibility for that leak as they have charged you enough but obviously not got it right. It looks like a fairly tidy S type with the desirable 4.0 V8. The engine is the star of that car! You need someone who knows what they are doing to assess the cam chain pulleys, and the gearbox. You need to know if it is worth spending more money on. I wish you well Joel and maybe rope one of us in if that garage doesn't fix that leak free of charge! I am happy to call Dell Motor Services myself if they don't fix it, because I think they jolly well should! Do they know you have 20,000 views on this so far for this? It might help motivate them to fix it! Good luck. 👍
You could have done the ignition coil yourself with an OBD II reader and then buying the coils off the web. The expansion tank was probably a DIY proposition too. That engine would be great in my Stag, the Triumph V8 in it has died. Frigging the ECU would be too much of a pain though, I think.
My old s type had a similar appetite for eating expansion bottles initially thought was a thermostat stuck closed but turned out to be my left hand head gasket failed pressurising the expansion bottle
I have a S type 4.0. expansion tank is a pig to change. Lower hoses have quick release joints that are not easy to get to. I got a pressure test kit, should have been supplied as tool kit. Seals on the front of the V and water pump+ plastic thermostat housing all weak design. Upgrade as you go.
I had one of these and very nice it was too, it also kept having a miss fire, it turned out to be water running down the windscreen onto the engine. I cured it by reversing the rubber near the bottom of the screen.
Re the cooling system, due the the cars age, it would be prudent for piece of mind to replace every piece of rubber attached to the cooling system. If not is it the case you will always wonder and spend your time staring at the temp gauge. I’d change the thermostat and water pump as well
The AJ-V8 4.0 engine is bullet-proof, a great engine, good enough for another 100k. Expect a few niggles and cosmetics for the price, soldier on I think you have a good car. I have an 18-year-old XJ8 with the 4.2 lump butter off silk, I've had some niggles recently the drivers door failed to open and needed the module replaced along with the door catch...couple of hundred sorted it.
I have no wish to scare the pants off you but I think you may be suffering from a head gasket issue. A blown head gasket possibly across the cylinder which needed the spark plug can, once the engine reaches temperature, begin to pump compression leakage into the water jacket of the engine. This will force water out of any place it can and in some cases even explode the filler tank. I would get a compression test done and look closely at the spark plug cylinder for a variance in compression Lbs PSI compared to the other 7 cylinders. Great video by the way Subbed and liked. I have the later 2007 2.7 diesel version. That has had some water issues too.. The thermostat housing which just really a water flow junction box and has no thermostat in it at all, decided to split. But that was down to old age. I changed that and then the heater control valve gave up. I have now bought shares in an antifreeze company. Despite that I love the thing and wouldn't part with it for all the tea in china. I bought the car in August this year for £2500 because it was spotless. Iv'e changed the cam belt and the rear high pressure fuel pump belt and because of the disgusting state of the engine internally with the DPF system I have now cleaned all the soot out and blanked the EGR valves on the turbos so its not recycling its own farts anymore. Good luck I hope you get yours sorted and if you need parts at reasonable prices check out autodoc.co.uk really good if you don't mind a bit of a delivery wait. I look forward to your next update.
Would check the water pump. Sudden loss of coolant is usually the symptom of broken water pump/thermostat. Hoses will trickle usually, unless there is a fairly significant split. That's my penny's worth of thought.
I have one of these jugs sat in my garden, failed the MOT on rotten sills. mechanically everything else spot-on, one of the best cars I had. I replaced it with a 4.2 which that now is sat on my garden! Point I wanted to make is with these jags there is one part that plays up a lot, and that is the valve for the heating system it’s down by the front bumper somewhere, but if that gets a blockage that could cause the problem with your expansion tank I’ve had issues over the years with heaters not properly working one side or the other and it’s these blasted valves not an expensive part, but I’m just wondering if that could be your underlying problem and issue?
The car has two loops, small one and big one. Once car is cold fluid circulates in small loop, when it warms up thermostat opens to the big loop, and probably you have a leak in it. The workshop should test it while repairing the tank, or it jus let go in the weakest spot once pressure got higher after first repair.
The 4Litre vs the 4.2- it's the other way around in Australia- most V8's advertised here are 4L. I personally would only buy the 4.2 as the problems (nicasil and plastic timing chain tensioners) were done with before the 4.2 was out. Had 2 XJ40's previously but the factory tuning was so mushy it didn't inspire. Compared to most cars of that engine size, it was like the accelerator cable was made from a bungee cord. Lovely and quiet though- made a 2007 holden commodore sound like it had rumbling front wheel bearings compared.
Is that an engine known for headgasket issues? Reason being, if the cooling system gets exhaust gas pressure into it, stuff is going to start failing (such as expansion tanks, and hoses).
It's the nature of old cars & cooling system leaks I'm afraid, fixing one thing highlights issues elsewhere, which is why it's worth buying a car you like, as you're more likely to forgive it! It's good you're realistic about it, still less money than a couple of months PCP on a new one.
Surely when they fitted the new coolant tank and did the work, they would have thoroughly tested it? New expansion tanks are available on eBay for between £35-£90, I ‘m sure the garage didn’t use a OEM part! Love the car, by the way, I had a 3.0 V6 and absolutely loved it, only problem I had was rust on the rear subframe, as I bought the car from a dealer near the coast, otherwise, a cracking and underrated car, would love another!
It’s a LR/Jag V8 so it’s going to have over heating issues, get used to it. There’s plenty of fixes out there, different heads, ARP studs, upgraded head gaskets, better expansion tanks. All make it into a reliable engine. Any air lock in these motors is a disaster waiting to happen, try water wetter, helps stop pockets of air in the block.
Have you made sure the timing chain tensioners have been done on this car? Not related to coolant but guaranteed to kill the car if they fail - 3.2/4.0 V8s are prone to it because they have plastic tensioners. They need to be upgraded to the later 4.2 metal items before it's too late
Considering the coolant is coming quote close to the tank best guess would be faulty new coolant tank or some hose was distributed when installing it that wasn't in the best of shape
Great vlog Joel! A Jag XJR is one of my dream cars, there are few out there. Jags are known for being unreliable, hopefully yours has no further issues once you fix that leak! Cheers Kirk
Are you referring to the older ones? I’ve seen some of the newer versions in the mid 20k range which is insane. I’m getting into an XJL 5.0 asap when I come home from Korea. Cant wait.
i would consider whether the THERMOSTAT is stuck in closed position, if so you'll have no heating if switched on, great video, thanks for sharing, they are good cars if well serviced, my 1st 1999 S-Type done 230000 mls and was still good, my 2nd 2001 S-Type has now done 209000 mls and still good, both had exp.-tanks replaced, also a few ignition coils.
Love the videos keep on posting them. Mostly interested because I’m a jaguar specialist and I have a 2001 s-type 4 liter I brought back from the grave😅
My old car had coolant issues for ages so I feel your pain and frustration, hope you get it sorted a cracked hose if the case shouldn't be too expensive.... Keep up the great content Joel! Also, if it was me... I would remove the old tax disk and stickers, but that's because I like a cleaner look on my cars and it's up to you!
Hi Joel, like the content dude. You got blue smoke, on start up. I hope its nothing. Tell your mechanic about the smoke ok. It can be rings, Head gasket. With the coolant issues, Its possible. I hope i'm totally wrong. Keep posting. 👍
hey Joel, i hope you can get the car fixed soon, I think that it could be a hose, it might also be the head gasket in my opinion and that can be really expensive, love the video's !
Perfection demonstration that an expensive car new, gotten on the cheap 20y down the line, still costs a fortune to put right. I have been there before with an 2000 Jag XK8 Conv AJ27 engine: problem after problem after problem. Poorly maintained in the past...and not particularly reliable from new. Cooling is a recurrent issue on these engines (AJ26, AJ27 and even AJ34) due to rubbish parts, notably the water pump with plastic propellers. Shortly after buying mine, heating was random, coolant was running low and needed top up every 100 miles. It did cost me both head gaskets to replace. Then chassis corrosion was next on the list. Then some electronic issues. A money pit, more often on jack stands than on the road. Got bored. Still have it as Sorn in my garage, may sell it for parts one day as I may well recoup some of my losses just with the convertible top in excellent condition. Sadly, that's the bet you have to accept taking on. It does not always end well, it actually often ends as a money pit to keep these things on the road, multiples of the purchase price...
I'm not familiar with the S Type V8 layout, but I had a very similar issue with my 2006 X Type 2.0 diesel. Your symptoms sound exactly like how my issue first started. Coolant loss from the expansion overflow eventually progressed to overheating. It took some tracing as it got steadily worse over a few weeks. Are you getting any signs of oil in the coolant/ water in the oil ? Any signs, get the engine oil cooler and oil stat checked, if it has the type where water coolant cools the oil. The oil cooler is an alloy sandwich block, where oil and water both pass through it. They corrode internally on the spot welds, allowing oil and water to gradually mix and pressurise each system. It can resemble a blown head gasket, but the engine still runs perfect until it gets up to temperature, then rapidly overheats when oil and water thermostats open flow to the cooler. High oil pressure gets into the coolant during running as it progresses. In certain running conditions, it will blow oily coolant out of the expansion tank in time. Once you switch off, oil pressure stops, and coolant pressure can force water coolant back into the engine oil, so check it too. The hardest job after swapping the oil cooler is flushing both oil, and mainly the water systems of contamination. I used a liquid housold detergent in the coolant for several flushes, then changed the oil, filter, antifreeze coolant and thermostats.
Check everything involving water, water pump slight leak ?, as you say hoses could of split, or the tank could be slightly damaged very unlikely tho, but the hoses will be the age of the car so wouldn’t surprise me if it’s that, or quite simply the garage may of missed something putting back together 🤷🏼♂️
I hope you’ve not poisoned that poor little black cat. Before throwing money at the Jag make sure the sills are rot free. My V5 Golf did the same thing the other week and it was due to a brittle plastic thermostat housing and it was far better when they were made of metal, but manufacturers like saving a couple of quid at the cost of reliability. But the car is 23 years old so I guess I can’t complain really. I could of repaired it myself, but I was more worried about the local Cats,so I took the car to the garage and washed the road down with a few buckets of water before setting off.
I looked at the V8 back in 2002, even then the stealers said don't touch the V8 as they had some major issues with them, ended up with a 3.0 for a few years. Liked the retro look but not that practical as a family motor, I think the v8 is rare for all the wrong reasons? Have had several X type and much prefer the S.
Most probably air locked or suspect thermostat not opening properly and should have been pressure tested and run up to temperature before you collected the car good luck joel let us know the fix 👍
Im so sorry to read that bill. I had to pause at 2.10. Ive been watching your videos for months, and this is the first time i felt inclined to comment. Someones mentioned you can get a new coolant tank for £35 on Ebay. Mercedes only want £45 straight from the main dealers- I doubt Jaguar will want a lot more. That work description is shocking. The fact the mechanic cant spell suspension, and says "That could be costly " on the job sheet is shocking. was this mechanic an alien? please dont say hes a family freind. To see hes saying hes investigating a coolant leak but not running it up to temperature is shocking. Hes actually telling you on the job decription to check it later when he knows youve left and it will boil straight up. I`m not sure why you took it there, but any (half) decent mechanic watching this will know you have been properly striped up mate. £555 for 1 spark plug , 1 coil, a water bottle , and a bottle of coolant is frightening . Ive noticed he hasnt itemised his labour hours either. oh dear. I havnt watched the rest of the video yet, but im guessing you just spunked 500 quid and the cars no better. I`d take it back mate- tell him to fix it or give your money back. If he doesnt play ball contact trading standards. th-cam.com/video/Gq6WME576ZE/w-d-xo.html th-cam.com/video/BUnvgKhWZdI/w-d-xo.html Oh my goodness I watched some more. its pissing out coolant after hes changed the tank. You seriously need to take it back, and word of warning i can see your cat was about to drink the spills - dont let him - it will kill him. Antifreeze is well known to kill cats. www.cats.org.uk/northherts/news/the-danger-of-antifreeze
Had this happen on my E39 BMW 540i - right hand head gasket had blown - Took a lot of work and money to put it right as the BMW v8's are a pig to work on ! - Hope you have better luck with the Jag as those AJV8's are nice engines unlike the BMW M62 !
After it gets fixed, please give it a full detail to bring it back to its former glory. Looking forward to the rest of your (hopefully not so troublesome) ownership journey. Leave the tax disk, maybe remove the parking permit but keep it with the car documents.
I hope you keep it everyone loves a jag Why not arrange a road trip up North once you get things sorted give it a run & see if the guys Matt from High Peak uses can get it looking back to its best be great content & he loves keeping these cars on the road 😀
Joel: Please keep your cat inside all times. Also, your cat being so close to even ingesting residually (even after adding water) toxic antifreeze, would be a horrible result.
Great content. I’d keep the tax disc all part of the provenance. Or get a new copy made up plenty of places online to do that. Personally I’d keep the original plates as well. You can have a go at fixing that rust spot yourself not too tricky and good content. Lovely car. I’ve got an 04 S Type R it’s the 4.2 V8 but both engines are super smooth with effortless power.
My son just bought an hyundai 4x4 spent $2.5 thousand on it but the mechanic didnt replace all the hoses and it overheated days later cooking the motor , set him back $9,000 aussie . Be careful mate!
Love the content on the Jag S Type. Tell the mechanics to do a thorough check on the Jag. I would gladly buy that Jag from you if I am there bro, nevermind the cost.
Thanks guys for watching! Are you liking the Jag?
Absolutely brilliant just wondering if you can do a one tank fuel video because I watched your range Rover video from Scotland thank you so much
Lovely car!
@@Tristanbirdyt I’m planning on doing a fuel economy challenge in the jag 👍🏻👍🏻 just need to make sure it’s reliable first !

As another guy said any garage worth its salt should have pressure tested the system, get them to do it this time , 😁👍

Keep everyone original mate. I’m on my 4th Jaaaayyg … love them… I’ll be upgrading next year to a Sportbrake … can’t wait 👍👍
Both of my Jaguar S-types needed new coolant expansion tanks. And the XF. It's a Jag thing!
I have a S type 4.0. expansion tank is a pig to change. Lower hoses have quick release joints that are not easy to get to. I got a pressure test kit, should have been supplied as tool kit. Seals on the front of the V and water pump+ plastic thermostat housing all weak design. Upgrade as you go.

Do love this shape of Jag, hope you get to enjoy without any more issues

Point I wanted to make is with these jags there is one part that plays up a lot, and that is the valve for the heating system it’s down by the front bumper somewhere, but if that gets a blockage that could cause the problem with your expansion tank I’ve had issues over the years with heaters not properly working one side or the other and it’s these blasted valves not an expensive part, but I’m just wondering if that could be your underlying problem and issue?
The car has two loops, small one and big one. Once car is cold fluid circulates in small loop, when it warms up thermostat opens to the big loop, and probably you have a leak in it. The workshop should test it while repairing the tank, or it jus let go in the weakest spot once pressure got higher after first repair.
The 4Litre vs the 4.2- it's the other way around in Australia- most V8's advertised here are 4L. I personally would only buy the 4.2 as the problems (nicasil and plastic timing chain tensioners) were done with before the 4.2 was out. Had 2 XJ40's previously but the factory tuning was so mushy it didn't inspire. Compared to most cars of that engine size, it was like the accelerator cable was made from a bungee cord. Lovely and quiet though- made a 2007 holden commodore sound like it had rumbling front wheel bearings compared.
Is that an engine known for headgasket issues? Reason being, if the cooling system gets exhaust gas pressure into it, stuff is going to start failing (such as expansion tanks, and hoses).
Like the positivity mate and the Jag is class
Cheers mate
Mate just putting it out there I bought my jag for 500 and abt 2-3 grand into it drives like a dream it's a 1997 jaguar x300
Mine have always been perfect! S types of this period in Australia fetch $8,000 and up.
Fantastic drive too,prefer it to my bmw 5 series i once had.
Not sure if anyone else comments on this, my cat died from antifreeze poisoning please wash away any spilt! I can see there’s a little black cat there
It's the nature of old cars & cooling system leaks I'm afraid, fixing one thing highlights issues elsewhere, which is why it's worth buying a car you like, as you're more likely to forgive it! It's good you're realistic about it, still less money than a couple of months PCP on a new one.
Really hope that cat didn't lick any of that coolant....its poison to cats and can kill them, slowly and painfully 😥
I thought exactly the same thing when I watched that part of the video.
Just about to cimment this as I'm watching it now I hope that cat didn't lick the coolant it will die ffs ... even humans.
Can confirm Lando did not lick any coolant and is absolutely fine
That would have been a cool cat 🤣
Great video Joel I have the exact same car in seafront same mileage as well lol 😊
Surely when they fitted the new coolant tank and did the work, they would have thoroughly tested it? New expansion tanks are available on eBay for between £35-£90, I ‘m sure the garage didn’t use a OEM part! Love the car, by the way, I had a 3.0 V6 and absolutely loved it, only problem I had was rust on the rear subframe, as I bought the car from a dealer near the coast, otherwise, a cracking and underrated car, would love another!
In fairness to the garage, it’s a specific part for the early V8 cars and so they were all circa £150+
Sorry to hear that man. I’m having jaaaag troubles at the moment aswell
It’s a LR/Jag V8 so it’s going to have over heating issues, get used to it.
There’s plenty of fixes out there, different heads, ARP studs, upgraded head gaskets, better expansion tanks. All make it into a reliable engine. Any air lock in these motors is a disaster waiting to happen, try water wetter, helps stop pockets of air in the block.
Have you made sure the timing chain tensioners have been done on this car? Not related to coolant but guaranteed to kill the car if they fail - 3.2/4.0 V8s are prone to it because they have plastic tensioners. They need to be upgraded to the later 4.2 metal items before it's too late
Considering the coolant is coming quote close to the tank best guess would be faulty new coolant tank or some hose was distributed when installing it that wasn't in the best of shape
Great vlog Joel! A Jag XJR is one of my dream cars, there are few out there. Jags are known for being unreliable, hopefully yours has no further issues once you fix that leak! Cheers Kirk
Are you referring to the older ones? I’ve seen some of the newer versions in the mid 20k range which is insane. I’m getting into an XJL 5.0 asap when I come home from Korea. Cant wait.
i would consider whether the THERMOSTAT is stuck in closed position, if so you'll have no heating if switched on, great video, thanks for sharing, they are good cars if well serviced, my 1st 1999 S-Type done 230000 mls and was still good, my 2nd 2001 S-Type has now done 209000 mls and still good, both had exp.-tanks replaced, also a few ignition coils.
Steel seal the one you want mate for coolant system. wish I was there by the car to apply it
Don’t do this. It’s a total bodge.
Heater control valve is just above where that's leaking. A common S type fault.
Hope the kitty didnt drink the coolant. They love it and its deadly.
Check the thermostat. And if any sludge in the water drain the whole lot thermostat refil fresh water
Had the expansion tank and the radiator go on my v6, still smell a bit of coolant now and again. As others have said might be heater control valve.
Love the videos keep on posting them. Mostly interested because I’m a jaguar specialist and I have a 2001 s-type 4 liter I brought back from the grave😅
I wish you ran a garage that I could bring my car to! Thanks for watching
My old car had coolant issues for ages so I feel your pain and frustration, hope you get it sorted a cracked hose if the case shouldn't be too expensive.... Keep up the great content Joel! Also, if it was me... I would remove the old tax disk and stickers, but that's because I like a cleaner look on my cars and it's up to you!
Head gasket problem with exhaust gas over pressurising the cooling system...
Begs the question was the expansion tank faulty in the first place?
I did wonder that, the garage assured me it was cracked. Maybe I should have asked to keep it
Hi Joel, like the content dude.
You got blue smoke, on start up.
I hope its nothing. Tell your mechanic
about the smoke ok. It can be rings,
Head gasket. With the coolant issues,
Its possible. I hope i'm totally wrong.
Keep posting. 👍
hey Joel, i hope you can get the car fixed soon, I think that it could be a hose, it might also be the head gasket in my opinion and that can be really expensive, love the video's !
Perfection demonstration that an expensive car new, gotten on the cheap 20y down the line, still costs a fortune to put right. I have been there before with an 2000 Jag XK8 Conv AJ27 engine: problem after problem after problem. Poorly maintained in the past...and not particularly reliable from new. Cooling is a recurrent issue on these engines (AJ26, AJ27 and even AJ34) due to rubbish parts, notably the water pump with plastic propellers. Shortly after buying mine, heating was random, coolant was running low and needed top up every 100 miles. It did cost me both head gaskets to replace. Then chassis corrosion was next on the list. Then some electronic issues. A money pit, more often on jack stands than on the road. Got bored. Still have it as Sorn in my garage, may sell it for parts one day as I may well recoup some of my losses just with the convertible top in excellent condition. Sadly, that's the bet you have to accept taking on. It does not always end well, it actually often ends as a money pit to keep these things on the road, multiples of the purchase price...
can't see any jokes about that maiden squirt :D
Joel, thank you I’ve been loo’s g forward to an update
Thanks for watching
I'm not familiar with the S Type V8 layout, but I had a very similar issue with my 2006 X Type 2.0 diesel. Your symptoms sound exactly like how my issue first started. Coolant loss from the expansion overflow eventually progressed to overheating. It took some tracing as it got steadily worse over a few weeks. Are you getting any signs of oil in the coolant/ water in the oil ? Any signs, get the engine oil cooler and oil stat checked, if it has the type where water coolant cools the oil. The oil cooler is an alloy sandwich block, where oil and water both pass through it. They corrode internally on the spot welds, allowing oil and water to gradually mix and pressurise each system. It can resemble a blown head gasket, but the engine still runs perfect until it gets up to temperature, then rapidly overheats when oil and water thermostats open flow to the cooler. High oil pressure gets into the coolant during running as it progresses. In certain running conditions, it will blow oily coolant out of the expansion tank in time. Once you switch off, oil pressure stops, and coolant pressure can force water coolant back into the engine oil, so check it too. The hardest job after swapping the oil cooler is flushing both oil, and mainly the water systems of contamination. I used a liquid housold detergent in the coolant for several flushes, then changed the oil, filter, antifreeze coolant and thermostats.
Definitely keep it, restore it by giving it a deep clean inside and out and keep it as original as possible 👍
oh no! I saw a little kitty cat 6:30 about to drink some coolant.. That's gonna kill it..
Got an s-type but the 2.7 diesel. Lovely cars
Check everything involving water, water pump slight leak ?, as you say hoses could of split, or the tank could be slightly damaged very unlikely tho, but the hoses will be the age of the car so wouldn’t surprise me if it’s that, or quite simply the garage may of missed something putting back together 🤷🏼♂️
Does this have the plastic thermostat housing that the V8 XJ of the same period had? If so, they are a known weak point.
I hope you’ve not poisoned that poor little black cat.
Before throwing money at the Jag make sure the sills are rot free.
My V5 Golf did the same thing the other week and it was due to a brittle plastic thermostat housing and it was far better when they were made of metal, but manufacturers like saving a couple of quid at the cost of reliability. But the car is 23 years old so I guess I can’t complain really.
I could of repaired it myself, but I was more worried about the local Cats,so I took the car to the garage and washed the road down with a few buckets of water before setting off.
I looked at the V8 back in 2002, even then the stealers said don't touch the V8 as they had some major issues with them, ended up with a 3.0 for a few years. Liked the retro look but not that practical as a family motor, I think the v8 is rare for all the wrong reasons? Have had several X type and much prefer the S.
Most probably air locked or suspect thermostat not opening properly and should have been pressure tested and run up to temperature before you collected the car good luck joel let us know the fix 👍
It's burning oil too, keep a close eye on your oil level
Don’t forget to replace the pollen filter as well 🙈
Im so sorry to read that bill. I had to pause at 2.10.
Ive been watching your videos for months, and this is the first time i felt inclined to comment. Someones mentioned you can get a new coolant tank for £35 on Ebay. Mercedes only want £45 straight from the main dealers- I doubt Jaguar will want a lot more.
That work description is shocking. The fact the mechanic cant spell suspension, and says "That could be costly " on the job sheet is shocking. was this mechanic an alien? please dont say hes a family freind. To see hes saying hes investigating a coolant leak but not running it up to temperature is shocking. Hes actually telling you on the job decription to check it later when he knows youve left and it will boil straight up. I`m not sure why you took it there, but any (half) decent mechanic watching this will know you have been properly striped up mate. £555 for 1 spark plug , 1 coil, a water bottle , and a bottle of coolant is frightening . Ive noticed he hasnt itemised his labour hours either. oh dear. I havnt watched the rest of the video yet, but im guessing you just spunked 500 quid and the cars no better. I`d take it back mate- tell him to fix it or give your money back. If he doesnt play ball contact trading standards.

Oh my goodness I watched some more. its pissing out coolant after hes changed the tank. You seriously need to take it back, and word of warning i can see your cat was about to drink the spills - dont let him - it will kill him. Antifreeze is well known to kill cats.

10.30 say that regularly do you Joel?😅 I'd also get rid of the tax disc
How did you swap your wiper blades?
Was waiting for this vid 😂 also waiting for my £1000 3.0 V6 s type to explode 6 months and its still going strong 🤞🤞
If the wipers are structurally okay, could you just paint them? Just a thought
Seems like its coming from the heater valve, or its pipes.
Worth doing an oil change at the same time as the air filter? Fantastic content
Had this happen on my E39 BMW 540i - right hand head gasket had blown - Took a lot of work and money to put it right as the BMW v8's are a pig to work on ! - Hope you have better luck with the Jag as those AJV8's are nice engines unlike the BMW M62 !
After it gets fixed, please give it a full detail to bring it back to its former glory. Looking forward to the rest of your (hopefully not so troublesome) ownership journey. Leave the tax disk, maybe remove the parking permit but keep it with the car documents.
The wipers are rusted out?show the underside its mot fail time
Good luck Joel. Might be better just to rent the Jag out as a spare room.
Not keen on the jag Joel but look forward to seeing what u do with it
Hi Joel, it’s such a hallowed Jaguar! Hopefully it’ll run as seamlessly as the old Range Rovers on the channel✌️
Water pump or HGF? Im not expert lol
Keep the Jag Joel, we like the content, perhaps in the future how far on a fuel tank run?
I hope you keep it everyone loves a jag Why not arrange a road trip up North once you get things sorted give it a run & see if the guys Matt from High Peak uses can get it looking back to its best be great content & he loves keeping these cars on the road 😀
Hey, what shop did you use? My e39 is removing blue smoke and looking for a shop to get it repaired or find out what the problem is
Does this have Aluminum heads..?
3.17 It's a head gasket!
Joel: Please keep your cat inside all times. Also, your cat being so close to even ingesting residually (even after adding water) toxic antifreeze, would be a horrible result.
Great video thank u and good luck
Great content. I’d keep the tax disc all part of the provenance. Or get a new copy made up plenty of places online to do that. Personally I’d keep the original plates as well. You can have a go at fixing that rust spot yourself not too tricky and good content. Lovely car. I’ve got an 04 S Type R it’s the 4.2 V8 but both engines are super smooth with effortless power.
My son just bought an hyundai 4x4 spent $2.5 thousand on it but the mechanic didnt replace all the hoses and it overheated days later cooking the motor , set him back $9,000 aussie . Be careful mate!
Didn’t you have the same problem with the z4?
Love the content on the Jag S Type. Tell the mechanics to do a thorough check on the Jag. I would gladly buy that Jag from you if I am there bro, nevermind the cost.
Thanks Frank, glad you’re enjoying the content!
Didnt the garage run / test the car after the work ? If it happened within 20 miles , great video Joel keep'em coming
