If I can safely dodge a second fill/drain that makes life easier for sure.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Bought a 97' base Boxster with 100K, and I'm going to do a new WP, thermostat, and a thorough coolant flush. Not sure what kind of coolant is in there right now, but it's not pink. My question is, does the order in which I do all this matter? Drain system, replace parts, flush with water, drain again, and then add new coolant as final step? Am I overthinking this? Thanks in advance for your help.

POST 2Original post

I don't know that you need to flush with water - I suppose if you wanted to make sure EVERY LITTLE BIT of the old coolant got out, you could, but you are draining from the lowest point on the car, so you should get most all of it. Anything that is left should be sufficiently diluted in the new coolant. Also, original coolant in a 97 is likely yellow/green.

POST 3 / ORIGINAL POSTEROriginal post

Thanks very much. If I can safely dodge a second fill/drain that makes life easier for sure.

POST 4Original post

I’d flush it with distilled water if you are planning on not using the factory anti freeze; the factory fill is well known to “not play well” when mixed with some aftermarket stuff………….

POST 5 / ORIGINAL POSTEROriginal post

Thanks Jeff. This was a concern of mine as I don't really know what's in there. A distilled water flush it is then. Any thoughts on using the Liqui Moly coolant flush? And I was considering using the Zerex G40. Good as the Porsche?
