I cant believe how many coolant hoses are on these cars or how they keep leaking. Speaking of leaks I had my indy replace the leaking Trans cooler lines and the ready to burst oil cooler lines and the oil pan and gasket(also leaking). I picked the car up drove 3 miles and yup another steam bath. I went back and told them I think they may have nicked one of the intercooler hoses while working on the oil cooler lines. I wasn't sure so they pressure tested the system and it ended up being one of the heater hoses at the firewall. They told me it is in such a tight space they have to take all the cowling off to fix it. I just spent $1800 and who knows how much this will cost. So much for Holiday cheer. What is it with these hoses? I love this car but I'm getting Tired of taking a bath with this car steam or otherwise.

 

Yes with the inter-cooler stuff it adds up to a lot of hoses so way more chances for problems.

For the cost of the car I wish they had upgraded to silicone hoses for everything. Probably would last the life of the car.

well the repairs clearly getting out of hand, but I think the problems are not all connected. The trans cooler lines are probably related to winter salt corroding the lines, after all you do live in New England! I know well and live in NH. Do you have the bottom shroud still in place below the engine? That should protect it a bit. The heater hoses are in a totally different area than the trans cooler lines. Has the car overheated in the past? That can lead to short hose life.

FYI recently repaired transmission cooler lines on a 2007 Cadillac, so you should not be surprised about that repair.

The point I think I was trying to make is that on a 96K dollar car(and yes the under panel is still there) if you are going to make complicated cooling systems with flexable oil, water and oil lines I think they should have used a higher quality of rubber or silicone to stay together. I've owned 20 year old chevys with original trans cooling lines driven in New England and never had to replace them. Every hose or line in this car (it spent 7 years of its life in South Carolina) leak and continue to leak. I am sure in short time I will replace every hose and line on the car. That being said I still love the car.

 

you should see the rust on NH cars, frames, cooling lines, etc and you would think differently about how fast metal can rust. I don't understand the hoses going out so quickly unless the car has overheated. I have never seen a car with silicone hoses, but they would certainly last longer

I feel your pain. I've got a leak, from what I'm told are lines that run under the supercharger. I can't find them on a diagram..... Now it seems the PS is acting up ugh LOL

 

You are correct RyeJag as far as more salt in NH. I've spent my whole life in New England and you guys in NH have the nicest main roads around because you salt your roads like I salt French Fries. Great for winter driving to Wildcat Mt to ski but not so good for our cars. No I dont think my hose and line problems are from salt but more like heat and age(no overheating history) just More like Ford Focus parts on an expensive English Lixury car.

 

ooootis,
When the hose under my Supercharger goes and I know it will I think that is when the car goes too. I hear that hose is a pain to replace. If Im not mistaken the supercharger has to come off.

 

Correct, the supercharger has to come off for this $10 hose. What miles has the car done ? This hose might already have been replaced.

Just to say that the tranny lines and oil leaks are not steam, they're oil !

 

The car has 135k miles on it and has been well taken care of with full records and always cared for by Jag dealers under extended warrenty up until now. I obviously know that the oil is not steam but it was to make the point that all the lines and hoses (most of them cooling system hoses) seem to be going all at once. I looked at all the service records and they dont list R+R supercharger to relace coolant hose so I am thinking it is the original. If that is the case and it goes there will be a very nice super V8 with every option and 20" Sepang wheels up for sale. I'm afraid that would be the last straw. I'll keep my fingers crossed I just love this car so I am going to think positive and hope for the best.

 

Fraser,
How many hoses am I dealing with and where does the run start and end? After the S/C is off how difficult access wise is it to swap out?

 

It was at a UK Jaguar Enthusiasts Club seminar for the X350 series in 2011, that I learnt about this little hose that needs the SC to come off and is one of the few jobs where the labour involved is so disproportionate to the part cost. The seminar was at the Visitor Centre of the Jaguar Castle Bromwich factory in Birmingham. The chap who told us all about the "issues" was Dave Marks who has an independent Jaguar shop in Nottingham.

I am sure a little ingenuity can replace the part with something more durable, like a copper pipe or something. However, I have yet to see a post on this aspect.

 

That makes 2 of us since I have done a search here to no avail. I guess I'm going for it in the spring. Can't drive farther than 40 miles without the low light illuminating.

 

Of course the commonest coolant leak point is the plastic header tank. Actually mine is OK, but I'm not sure it's the same as the V8s, (my car has the Ford-origin V6 3 litre engine)

 

Well the Jaguar perspective may be once you replace the hose you will likely never have to do it again!. Any idea of how long it takes to pull the S/C and what other maintenance can be done at the same time?? trying to spin it all in a positive light!
hopefully I have some time before mine is due 04 XJR with 76K miles.

Does any Forum member have an exploded view of the area of this hose showing where it is located? It sure would be helpful to see what we are up against before starting the job.

 

Fixed another small leak yesterday, and it was my fault. Yes, when removing/disconnecting the original hoses for the under-the-S/C hose replacement, I knew there was a chance that I might damage hose' cord in the process of prying them loose. Based on the location of the leak, that's what I did. I suspect that others have similarly damaged their hoses along the way.

 

Bob, How long did it take to do the job? Did you happen to take any pics for Forum? How difficult would you say it was?

 

Here are a few photos that might be of interest.


The most difficult part of the job was the fiddling near the throttle body. Lots of knuckle scraping and finger cutting surfaces back in those tight spaces.


The first time apart and back together, it took 8-10 hours. Second time, all but for lifting the S/C was less than 4. Once I got it figures out, it was much easier.


Hope this helps.

 

Thanks RC!@ Pic is worth a thousand words. What does the far side of the hose hook to? It doesn't install in the same area that you have it laying??
