With the noise, I am moving on to the water pump, which, after reading the posts on replacing the coolant tank, it will be easier and cheaper to replace the pump!

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Just as I was pulling into my driveway this morning my 97 started making a loud groaning noise under load. After I pulled into my driveway I noticed that coolant was leaking from the bottom of the car towards the middle near a radiator hose connection. Steam was coming from the right, passenger side engine grill. As I was jacking up the car to find more clues, the leak stopped. In other words, once the expansion tank was emptied, there was no more leak. Before I start pulling things apart, does that mean that it must be the expansion tank, or could it be the water pump? What I mean by that is if it was the water pump, would some five gallons of fluid leaked or once the coolant reached a level below the pump, the leak would stop. I assume if it was a bottom radiator hose most or all of the fluid would have leaked. In my Bentley, I did not see instructions on the expansion tank removal and replacement. Anyway, that's what I know at the moment. As always, thanks folks!

POST 2 / ORIGINAL POSTEROriginal post

UPDATE: I just noticed that the expansion tank did not empty after all. It is just below the minimum mark, but I know it was full. With the noise, I am moving on to the water pump, which, after reading the posts on replacing the coolant tank, it will be easier and cheaper to replace the pump! Anyone have a recommendation on the best reman water pump? At NAPA, Parts Bin, etc., they are all priced around $150 or so. Thanks.
