I have just been checking on the right antifreeze for my 04 996 c4 as I have just changed the water pump and according to the Comma site you should be putting in the approved Comma Xtreme G30 just check on their website also you should not mix antifreeze so flush your system anyway and refill for about 5 years of protection

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.

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

Outcome without a verified action link

After the second slightly longer run and the cool down it was about half a litre and finally after a third good run and cool down there was no change in the level.

POST 2Original post

I changed over to G30 as soon as I bought my last C4s, fantastic offers on EBay, compared to Halfrauds. Unfortunately I’ve just picked up my new 996 turbo and it has crappy blue, so got to go through it all again. Simon

POST 4Original post

When I refilled my coolant after water pump and radiator changes, I left the burp valve open on the expansion tank for three heat cycles. After the first short run to get up to temp and then cool down I had to add just over one and half litres of coolant. After the second slightly longer run and the cool down it was about half a litre and finally after a third good run and cool down there was no change in the level. Both rads were getting hot and fans working as expected.
