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.

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

POST 1 / ORIGINAL POSTEROriginal post

So my recently acquired purchase appears to have some kind of green coloured coolant in it.  I suspect this is HOAT (not old old green) based on what is typically sold in AU. Should I get it flushed and replaced with red OAT coolant? Is HOAT that bad for it?

POST 2Original post

Can’t answer your question, but it’s never a bad thing to put the right one in and know that its been done and when. If no record of brake fluid flush, good idea to do that too just for peace of mind. Both flushes cheap and easy ... 😀

POST 3 / ORIGINAL POSTEROriginal post

Quotes source post: 328537

Very salient point! Yep, sold!

POST 4Original post

I'd recommend flush and change coolant, also as mentioned brake fluid. Not sure what your cars records are like, so could be due anyway. See attached, this is also what Dave from Nurburgring Mechanical uses/used on my 997

POST 5 / ORIGINAL POSTEROriginal post

Yep it's all happening. 😄 1. The old yellow coolant tank was... surprise! Old yellow and cracked! So that explains the small leak and was on my to-do list anyway.  When it goes... flush and OAT replace it is. 2. Brake hoses are getting old according to the guys as Autohaus so... replace and flush there too!
