I had a EUR 90K (at that time USD 120K) company car that leaked both coolant from the tank, and used cheap clamps on power steering return that resulted in loss of all powersteering.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

13 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

about a dinner sized puddle under the driver's side rear this morning See attached pic... fluid feels oily - but not sure what it is. Also tail pipe has white residue? Seems to be dripping from the exhaust pipe?

POST 2Original post

Looks like exactly what happened to me, if I was a betting man I'd bet its coolant and your coolant expansion tank has developed a crack. Is the coolant low in the tank?

POST 4Original post

I'm also a member of the leaky coolant tank club.

POST 7Original post

No, it's made from genuine imitation goat bladder. They NEVER leak!

POST 8Original post

been there too! Why can't a car costing over $95,000.00 (mine did) have a coolant tank that will last 40k miles? Not be such a PITA to replace? and not cost over $300 to replace, just for the part? The coolant tank on my jeep has lasted over 100k miles and is still perfect and when it goes it will cost $14.68 and I can replace it in about 2 minutes. I know, I know....just sayin'

POST 9Original post

Mine leaked, but that was way back when I had the factory warranty, lucky me!

Well, to be fair, dad had a $100K S class sedan that leaked coolant. I had a EUR 90K (at that time USD 120K) company car that leaked both coolant from the tank, and used cheap clamps on power steering return that resulted in loss of all powersteering. Just sayin'.

I hear you. My 1987 Wrangler has been the most reliable (and uncomfortable, noisy, etc.) vehicle I've owned. And yeah parts may as well be free compared to our p-cars.
