2001 XKR Silverstone here; coolant reservoir is leaking at the seams under pressure as duplicated via my pressure test kit.

The question is, has anyone successfully repaired on of these or better to replace.

If so, any recommended suppliers for better ones or a good fair price OEM?

Thank you!

 

Far better to replace than try to fix. You wouldn't want to think you had repaired it to then find your engine melting through lack of coolant.

You could try SNG Barrat for parts.

 

+2 !

 

Do you mean the black plastic Expansion Tank (item 1) in the engine bay or the Atmospheric Recovery Bottle (item 11) behind the RH wheel arch liner?

The Atmospheric Recovery Bottle can be repaired but I've read too many reports of disappointing results attempting to patch the Expansion Tank. Far better to bite the bullet and replace it. It comes complete with Pressure Cap (item 2) and Fluid Level Sensor (item 4).

Definitely the Black Plastic Expansion Tank (Item#1).

Thanks for the advice - I don't want to strand myself if it blows apart, and nor would I try to continue to drive a vehicle that was leaking or starting to overheat.

 

just replace it, you can find them for a good price on ebay. It is an easy job.

 

+4 Replace SNG Barratt $144, new motor $10,000

 

I just had a hose fail on one of my cars, it overheated and while I had popped the hood to take a look, it gave up the ghost. I have second degree burns on about a third of my right forearm. It's healing well but it's painful. This was an 04 Audi A8. I was picking up Chinese on a date and I was lucky that my dress was cotton and the Chinese place helped fix me up with ice packs. 45$ hose...now I'm not just checking, I'm shotgunning all my hoses on that car.

I'm glad when my XKR's coolant expansion tank failed last year that I was only out a new tank and the coil for the cylinder it leaked all over. 230$ total, no burns, no toasted engine. Buy the 145$ tank. It takes five minutes to install.

 

We had several attempts to make repairs and all failed. Replace it!

 

I fiddled with mine for a few months. In addition to a slight leak, the fluid level sensor had crapped out. I found a brand new tank with sensor on ebay for about $140. I'm not sure if you could even get the sensor out of dealer that cheap.

It may sound like a wee bit of scratch, but it was money well spent. Replace it.

Ciao!

 

After shopping around, I went with SNG Barratt. $144 plus $12 shipping to Florida was the cheapest I found and more than reasonable for the OEM part from a company I know I can trust.

I'll try to post some pics and video of it when I'm done.

 

It can be repaired, this is how I did mine 3 years ago.

Nothing else works because the tank is under pressure and HOT MOISTURE, this is why everyone else s attempts have failed.


I recommend replacement because you do not know what area is going to crack next lol, but mine has been fine for 3.5 years

 

REPLACE IT! Want to risk a motor for a 20 dollar patch fix when the a new one is only 150.00 more or less.

 

I had a leak around my tank which turned out to be the air bleed hose but as the coolant was around the seam of the tank that was the assumed leak. I would have hot air welded it as suggested above. It is a reasonably straight forward process but needs a proper heat gun with nozzle to direct the air, a guide/shoe to feed and force the filler rod into the weld pool and of course the filler had to be the same plastic as the tank. I'm lucky because we use this equipment where I work but any decent plastic fabricator should be able to weld thermoplastics.

 

If mine ever leaks again. I am fabricating a aluminum tank that will never fail.
