One of the best fearures of old XJ/XK8 Jags was how quiet and sophisticated they were, so relaxing to drive, still having pace and power. This current trend of needing so much noise it must be fabricated, is just stupid.
That was exactly the appeal: it always had more without any effort and all the noise and vibration that causes. The suspension worked similarly, in that it always seemed more capable than you are. And why do modern engines make such a horrible noise as well as so much of it?

Myself I've found that it's always quicker and easier to remove the engine the same way the manufacturer installed the engine. If they installed it from the bottom then it usually comes out much easier that way. My 2013 focus ST had a sound symposer that did the same thing. I ended up removing the diaphragm and filling the entire block with jb weld and removing the hose from it. The diaphragms we're known to burst and cause a major vacuum/boost leak.

I LOVE the fact that my '10 VW CC 6MT is silent when it's driving. It's not super quick, but it's amazing how fun it is to drive. A big car with the GTI/GLI CCTA and 6MT is hilarious. In fact, I hung out with a bunch of cops in the early 90s told me to stop putting stupid exhausts on our cars. They simply said they would roll down their windows and wait for us to come out from our cover. LOL!
The knock sensor is integrated into the symposer? Or it's wiring is connected to it anyway? Did I hear that right? It would be great to if you could provide a guide to how to disconnect/remover the symposer in the right way to eliminated any failure points the symposer creates, and to do that without causing any codes to be thrown.
I removed the symposer and capped off the hoses. I always hate fake noise, no matter the delivery method, including on my S3. What really sucks about the symposer is that there's no way to adjust volume like I can on my S3, though (via OBDeleven).
While you’re there. The plastic coolant fitting in the valley needs replacing. They’re notorious for failing and you don’t want to take the charger off again if it leaks.
Only one reason to have something like this is in an EV. My car makes no noise, and the synthesized sound is just a tone that goes higher or lower depending on whether you accelerate or break. No its not a tesla. It's not even a car sold in the states...
@@timothyharrison8953 just some bongs. And absolutely nothing else. because it's always a software issue. The one time I had it break was a bad charger. Was fixed by disconnecting the 12 volt battery. And yeah, my name doesn't inspire perfect knowledge of English, I know.
FRS has that shit too! I spent an hour, helping a friend try to figure out what this big hose went to. His had an aftermarket intake. Turns out it was piping the intake sounds too the heater core box.
Wow...major work on this Jag. Intersting concept the symposer , though more to worry about and from others experience definately caused mejor issues. Looking forward to this rebuild.
I was surprised about these systems on modern cars, when I found out about them back in 2014. VW have the Soundaktor, it's a speaker in the scuttle that makes engine noise that resonates through the scuttle to improve the engine sound. I disconnected it on my then new Beetle 2.0tsi, the engine sound was so disappointing without it I plugged it back in.
In the book Bridge Over the River Kwai, an engineer describes his soul sucking job redesigning a girder in order to use the least amount of metal but still ensure maximum strength. I believe the engineer who designed the Symposer probably had a similar experience.
Toyota/Lexus LFA had the best symposer type device. Because the carbon tub distorts the sound they spent a lot of time to get the exact natural sounds into the cabin that would work within the tub.
13:28 100% agree with you on that JR, just had to replace one of the coolant lines on my dad's 07 R/T Charger. Of course, it was one that ran under the intake, making my job more tedious when it really didn't have to be.
for those watching. I've removed the engine and transmission in my 2017 F-Type S and it's actually pretty well designed to make that happen easily. disconnect exhaust, drive shaft, coolant lines and fuel lines etc., and then disconnect two big wiring connectors. Then remove 8 big subframe bolts and out it drops just clean as anything. Goes back up nicely as well. The expensive part is the refrigerant for the A/C and getting that recharged.
Be careful, the symposer solenoid connecter and engine coolant sensor one, on the rear coolant manifold, are the same, it is possible to plug them in wrong, I have driven a Range Rover Sport, same engine, with a bad symposer and it made a ton of supercharger noise, most of the time these engines don't have any supercharger sounds, have fun.
@@jamesroyafm24 yep, the temp sensor has a 5 volt signal from the PCM and receives part of that back and the solenoid gets a power and ground for activation , if they're ewapped it's a real bitch to correct it
The 2014-2017 Chevrolet SS (Holden Commodore) comes with a "kazoo tube" that pipes intake sounds into the cabin under heavy acceleration. It's a feature that is so commonly deleted that RDP actually sold a custom block off plate to cover the firewall hole resulting from removal. An electronic system at least allows you to turn it on/off.
I remember that one time I was putting an engine in a Ford fusion 4 cylinder. Service data said out the bottom. Looked easy enough to me. Old engine came out easy enough just had to remove the harmonic balancer. Removed it on new engine and it went right in. Rolling engine over to do the torque converter and it clunks. Valves hitting piston. Here a lot of Ford 4 cylinder engines are not keyed and when I loosened the crank pulley I also loosened timing gear. Lesson I learned was follow service data it's usually for a reason.
The Lexus F cars with the V8 have a mechanical/vacuum actuator that opens the intake box when the engine is above a certain RPM to drastically increase sound. Thankfully, it's easily accessible though. Also, It's Toyota made so... NOTHING BREAKS.
... well, it _is_ a Jag, and that does kinda go right along with their crazy way of doing things. Hell of a system just to get sound inside though. I agree with you - want noise? Roll down the window. Or maybe when the car is getting made, they should have a check-box on the build sheet where if someone _wants_ it to be loud inside, they omit some (or all) or the cabin insulation.
July 30, 2022. I am 57 years old, and I have a new word in my vocabulary. Aggregator. (New to me, so, back off, all you know it alls!!!). Thank you, John Ross!
Today on WatchJRGo, we use a left handed screwdriver to find the elusive canooter valve. Using the left handed socket extractor along with the pipe stretcher we are able to repair this integral part of the Jags heart. Seriously, when the diagram popped up as a blank page, I thought it was done as a joke done with the most sincere poker face I had ever witnessed. That being said, I would like to thank you for not only the joke being on me, but for the coffee I got to clean up from the spit take when I laughed my canooter valve off.
My 20 Lexus RC 350 has a similar part on the intake tubing. It still creates sounds through the speakers but it first ports the intake noises towards the firewall to amplify them. Except the system on the Lexus is much more simple, I don't really think it can fail. I'll admit it sounds pretty good. There is actually a slider on the dash where you can turn up or down the volume of the sounds which is independent of the driving mode. You can put it in Sport but still turn the slider all the way off. I like the way they set it up. The first car I had that had this system was my Fiesta ST and it was completely mechanical. It was a pipe on the intake tubing that was ported into the car. This one could actually fail and create a leak. I eliminated that system because with an aftermarket intake and charge pipes you already got ridiculously loud intake noises.
If I could work on the Jaguar F type with Watch Jr Goes I would drink the shot of whiskey and the cold Bartle Skeets and pack up the Hash Pipe with Rocky and get all schmoked up.
This is less about making noise and more about feeling the engine. Jaguar does a lot of this kind of stuff. Did you know that the engine start button blinks at the same rate as the heartbeat of a resting jaguar when the engine is not running?
They have those sound symposer's on Porsche 981 Caymans and Boxsters and they actually work very well. Of course, the engine and intake manifold itself are only about a foot behind you, so it is pretty simple to do. Keep up the good work!
"No one needs coolant lines under the manifold" Porsche Cayenne Engineers: "Y'know what would be awesome to put in the middle of the vee on our V8s? The Starter! Porsche CEOs : Brilliant! Now run plastic coolant lines next to it!
I remember having a merkur scorpio on our lot with a non functioning hvac system due to a tiny unnecessary part that NO OTHER CAR would ever need. Since it was 10 years old, and that part was prone to failure, it couldn't be found and trying to bypass it made the car run horribly. I got lottery lucky and found one in my local pick a part.
JR trolled us all with that diagram 😅 Anyway, remove that silly symposer thing, weight reduction! I'm glad you read the comments, there must have been at least 50 over the past few videos about this Jag for you to get that HF table, if you're going to keep working on cars you're going to need one of your own, and shout-out to Ninja for offering to let you borrow his (again).
My 2016 camaro ss had a similar thing but off of the front of the engine and intake hose. Removed it and put a block off plate on the firewall and plug in the intake hose.
I like the Mini (and likely BMW) solution. An actuator on the exhaust tip that opens up a muffler bypass in sport mode. It's still got the resonator, and I presume SOME of the exhaust still goes through the muffler, but it gets louder without being obnoxious. Put it back in regular mode and it quiets right up. I've disabled 'AktiveSound' or whatever they call it that makes the noise through the stereo and it's perfect on my JCW.
I too, would prefer no fake engine sound, electronic or mechanical, piped into the cab. Not needed. Although the mechanical system pipes in real engine noise, and if the engine is making bad sounds, at least you can hear the problems, unlike an electronic system.
It’s the same system that they use with Mclaren. On a Mclaren it’s called an intake sound generator or ISG and they are a fairly common failure point, so much so that several aftermarket companies make small block off plugs to eliminate the unit completely.
I would put it back the way it was. That way when you sell the car you can say I just tuned up the Symposer and the super charger... Plus I would like to know how great this thing works as they spent all the time on it...
Eventually that corrugated tube that connects to the manifold will crack and cause lean codes. It’s better to get rid of it because Jag wants an arm and a leg for that replacement
Im not sure if you said that this car has had its heads off recently? but looking at the bolts on the rocker covers, they haven't been off at all or a very long time....
I’d sooner leave it out. If you want to hear noise, get the convertible. Is there a way of removing it without it throwing codes? I yanked the symposer of of my Fiesta ST
The HF table should be fine for how few times you need to drop an engine out. As with all HF hydraulics I'd recommend flushing out the fluid it comes with for some known quality jack fluid.
Let’s face it: the whole drivetrain packaging development exercise involved a full wheelbarrow of parts and a very long run-up. I despise fake sounds; the worst example I’ve experienced is the Mk7 Golf R which sounds inside like a Subaru boxer up to about 3k rpm and then what it would sound like after a legislation delete up to the redline. There is no reason to fit fake sound to a convertible. Legislation allows a noisy flare on startup; then keep it sweet & mellow up to moderate load; then open things up at higher load. My brother owns a contemporary Merc SLK350 and Merc nailed that strategy perfectly; it’s a joy to drive and listen to in all the situations. JR, I agree that leaving that noise simulator complexity enhancer out is the way forward. This is why custom exhaust fabrication shops exist 🙂
I suspect the coolant leak is the outlet pipe, the black plastic tube at the front of the intake valley, if you remove the two T30's you'll probably find the bottom of the pipe stuck in the block
Ford put something similar on the Mustang GT to compensate for the super quiet OEM exhaust system. Never understood choking off the natural sound and installing extra parts to produce fake ones.
BMW/MINI do it in a much more simple way. Pipe from air box direct to bulkhead/fire wall so you get the induction roar in the cab. Just a two inch box pipe , a small air filter bolted into the firewall.
Just need the right combo of powertrain and exhaust 😁 Have a solo catback on my G8 GT (one muffler where the resonator was), and it's fine at highway speeds. Get it over ~2500rpm and it starts to make some noise. The car is insulated pretty well though, never knew how loud it really is until I drove behind it.
Can the symposer be blocked off or bypassed without removing the supercharger on an F-Type? I ask because apparently mine went bad (cracked) and is causing a vacuum leak which is making the car idle rough. The dealer said it's a 7 hr. job at $242 per hour, plus about $300 for a new symposer. Seems ridiculous for a part that's not even necessary.
Great video as always JR, you always make repairing cars fun and interesting. I absolutely love this model Jaguar, and it is chuckle worthy when engineers come up with crazy ideas to solve simple problems. I for one don't have a problem with piped in engine audio, I suppose if it were a basic ride with subpar engine sound, it may actually be enjoyable. However, this is a Jag and they sing beautifully, in fact that is the best part about this car. I'd simply put an aftermarket exhaust system on it, and block off the provisions for the Symp-poser. (Simp + Poser lol)
This truck would be the perfect resource to help the Granger Area Chamber of Commerce, replace my primary mode of transportation from an accident that rendered me breaking every extremity in my body and seeing the worlds been on my mind
My Subaru BRZ has something similar (totally manual, on all the time), as did my NC Mazda Miata... they actually do work, but like I said, mine were both totally manual.
Ford did this also with the european focus rs mk2 and the fiesta st. System that will give some sound in the cabin but a lot of issues with the car. Boost issues and errors. I did have it also with my rs mk2. There is indeed a diagram inside and it is tearing apart.
If you're having trouble getting the cats removed, just park the car in a big city.

The HF table should be fine for how few times you need to drop an engine out. As with all HF hydraulics I'd recommend flushing out the fluid it comes with for some known quality jack fluid.
The diagram was very informative thanks
Lol I remember dad helping you with that coolant line. He said right then he’d never buy a jaguar 😂
Let’s face it: the whole drivetrain packaging development exercise involved a full wheelbarrow of parts and a very long run-up. I despise fake sounds; the worst example I’ve experienced is the Mk7 Golf R which sounds inside like a Subaru boxer up to about 3k rpm and then what it would sound like after a legislation delete up to the redline. There is no reason to fit fake sound to a convertible. Legislation allows a noisy flare on startup; then keep it sweet & mellow up to moderate load; then open things up at higher load. My brother owns a contemporary Merc SLK350 and Merc nailed that strategy perfectly; it’s a joy to drive and listen to in all the situations. JR, I agree that leaving that noise simulator complexity enhancer out is the way forward. This is why custom exhaust fabrication shops exist 🙂
Other supercharge dont have that.. The time u return that parts add heat protection on plastic flexible hose
Right up there with the turbo encabulator...
Jag with its quirks, NO K.I.S.S there. No need for fake sound.
I suspect the coolant leak is the outlet pipe, the black plastic tube at the front of the intake valley, if you remove the two T30's you'll probably find the bottom of the pipe stuck in the block
@WatchJRGo-FYI...Not that I really wanted to see it much, The cutaway to the diagram of the Symposer was a blank screen.
Same here all I see is a blank white screen.
It just keeps on giving doesn't it, watching now, I'm sure you'll get it going eventually 👍
Oh yeah, should be pretty easy to get out now, it's totally unhooked 🍻
The Gen2 NSX does a similar thing for engine sounds in the cabin
Ford put something similar on the Mustang GT to compensate for the super quiet OEM exhaust system. Never understood choking off the natural sound and installing extra parts to produce fake ones.
BMW/MINI do it in a much more simple way. Pipe from air box direct to bulkhead/fire wall so you get the induction roar in the cab. Just a two inch box pipe , a small air filter bolted into the firewall.
I've seen that, way better than all of this piped into intake 💯
I like my cars quiet inside.
What you said in the first 6 seconds is the life mission of every Jaguar engineer
I have always said, everyone should own a British car at least once in their life. Once should be enough.
Hard pass. I've owned over 50 cars, no VWs, no Toyotas (boring) and no British cars.
A little box to make Brum! Brum! noises has it come to this guys.
Just need the right combo of powertrain and exhaust 😁 Have a solo catback on my G8 GT (one muffler where the resonator was), and it's fine at highway speeds. Get it over ~2500rpm and it starts to make some noise. The car is insulated pretty well though, never knew how loud it really is until I drove behind it.
Just checked it was not April 1st, so, this apparently is a 'real thing'. You learn something new every day.
Can the symposer be blocked off or bypassed without removing the supercharger on an F-Type? I ask because apparently mine went bad (cracked) and is causing a vacuum leak which is making the car idle rough. The dealer said it's a 7 hr. job at $242 per hour, plus about $300 for a new symposer. Seems ridiculous for a part that's not even necessary.
if I recall correctly, Ford did the same thing for the 2005 Mustang GT.
Fascinating... European cars always amaze me with what is simple and what is overcomplicated. It's quite the juxtaposition!
I would do a Vehicor impression with that thing. "onto the pile!"
Great video as always JR, you always make repairing cars fun and interesting. I absolutely love this model Jaguar, and it is chuckle worthy when engineers come up with crazy ideas to solve simple problems. I for one don't have a problem with piped in engine audio, I suppose if it were a basic ride with subpar engine sound, it may actually be enjoyable. However, this is a Jag and they sing beautifully, in fact that is the best part about this car. I'd simply put an aftermarket exhaust system on it, and block off the provisions for the Symp-poser. (Simp + Poser lol)
This truck would be the perfect resource to help the Granger Area Chamber of Commerce, replace my primary mode of transportation from an accident that rendered me breaking every extremity in my body and seeing the worlds been on my mind
My Subaru BRZ has something similar (totally manual, on all the time), as did my NC Mazda Miata... they actually do work, but like I said, mine were both totally manual.
Ford did this also with the european focus rs mk2 and the fiesta st. System that will give some sound in the cabin but a lot of issues with the car. Boost issues and errors. I did have it also with my rs mk2. There is indeed a diagram inside and it is tearing apart.
What a shock British car not being easy to work on overly complicated
Wise words for Jaguar from JR. They should be followed.
That diagram was helpful
Informative. Thanks
Removing that system is a PITA members just plug the hose going to the megaphone to remove the noise from the cabin.
ive got 2 sovereigns 1 is a jaguar which is held together by rust and the other is a lwb daimler with the 5.3 and it aint fun to maintain the last one
Super simple design from that diagram
I think the engineers at Jag may have been eating edibles instead of gummy bears when they came up with that concept.
That's a highly detailed diagram!
Well isn't that the craziest thing I've ever seen.
Mini has a similar thing but no on off valve. Always on. Always simple
Another great video from JR. Thanks
