Thanks a million Adam! I own an 1987 xj6 all original and a 1983 xj6 with a big block Chevy motor I installed. Your hard work has been invaluable to me and several others who tries to do their own repairs on these beautiful cars!
I found it quite common on my older jags that the coolant sensors would be at least slightly off. An old school mechanic once told me that every time he changed his coolant he would remove his or any coolant sensors and give them a light sand to keep the signal measurement accurate. The build up internally from coolant not being changed regularly can slowly throw them off. I wonder if there’s any truth to that? Great video as always by the way! Keep up the great work! You inspire us all❤
Hi! Just like any temperature sensor, if it is coated, it will be slower to respond to temperature changes than if it is clean. But it should not make it innacurate.
Great 👍 video Adam. Sometimes with a Jaguar XJ6 4.2, it can be an easy fix, you just have know what you're looking for. I had previously owned two XJ6 4.2,...a '82 and a '85 and also a 1991 XJ40. Great looking and smooth riding cars. Keep up the great work. I always love your informational videos Adam.
I had a Series 21/2 (A 1979 with FI) that would be hard to start or die right away. Turned out the internal wiring in the Bosch plastic connector on the water temp sensor had gone bad due to a faulty crimp on the wires in the plastic connector. Spent many hours trying to figure it out. Replaced the plastic Bosch connector and it ran fine "ever after."
Hello, thanks for the videos, can I ask you the reference of the sensor? I've got the same problem and the one I found is really expensive..all the best, thanks
Good day Adam and that was realy a quick fix. Very interesting. I noticed that the oil pressure gauge only pick up to about the 3.Is it normal for the Series 3 ? Reason i am asking mine also lift up to the 3 and not higher. One off the guys did gave me some advice on your channel to check it with a old school oil pressure gauge.Still battling to get hold off one to see it my sensor is faulty. If i give a little acceleration it drops back to rest position as if there is no power on it.
@@LivingWithAClassic Last 6 cylinder Jag engine I rebuild was a mongrel to get the head off. Lifted it about 2 inches, it got stuck fast. Easy fix. Cut the studs, removed the studs from the block. Next, I removed the studs from the head, with some difficulty. I then remove the corrosion from the stud holes in the head, & ream 3mm oversize, fit stainless steel sleeves & studs then reassemble the engine with new rings after honing, new bearings & check with plastigauge, crank end float with dial gauge, check ring gap during reassembly, & use assembly lube during the process.
@LivingWithAClassic Any idea what's happening with this series 3 cold start? The resistance is coming in correctly. Once it starts it's absolutely fine, and subsequent starts are instant once it's warm! th-cam.com/video/VnYz3V2LUak/w-d-xo.htmlsi=JYmiJWu8jHae_fAe
Good for you but a bit disempowering for us head-scratchers. I mean it would have been nice to know HOW you suspected Temp sensor first without even considering Computer processing unit faults, weak fuel pumps, partially blocked filters, cold start enricher, coil, sticking flapper or hot wire, etc etc. Weak fuel mix usually caused by faulty temp sensor because ????? Never take your back-knowledge for granted when teaching novices.
Nice work. Always great when it's an easy fix.
It really is
Adam. As l often say you never have a problem , always a solution . And as you say, it's an easy fix .......if you know what your doing ! Thanks Adam
Great! I'd also like to see work done on XJ40 and X300 cars, not just the older ones. Thank you!
Awesome diagnostics and fix Adam 👍
Thanks Anton!
Always loved the 4.2 XJ6 I had 3 of them during the day
They’re great cars

Great Result, well done
Great work - as usual - Adam.

Very nice......now how about something on the XJRS
Hab the same problem with my tvr nice video 😊
Which TVR do you have?
@@LivingWithAClassic tvr chimaera 4litre hc
Great job!
You know much bout the xj6 vanden plas models?
Nice fix ! Nice outbuilding
Thanks!

Nice quick fix Adam
Well diagnosed, can I ask , as I’ve never owned an XJ , is the oil pressure gauge a bit lazy ( seems a bit low considering engine is cold ) ?
Just goes to show that things look easy when an expert does it.
Nice job.
Thanks!
Wow Thanks for the video 😅
please buy this car ... its too nice to take it apart
My Favorite XJ6 Trouble shooting.
The cylinder heads on those can be awkward to remove, because of corrosion issues.
It’s not really that difficult. I have my tricks
