Again I apologise in advance for going over old ground, but I’m having them fitted next weekend and don’t want to make a decision I’ll regret later.

Having recently noticed a slight loss of coolant, which is down to the offside front radiator, I’ve decided to replace both sides.

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

Coolant question
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.

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

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Good morning I know you’ve heard this question many times, but after reading the comments I still need your help I’m afraid. Since buying my 2005 996 C4s only 2 months ago, I’ve replaced the exhaust, tyres, battery and had all 4 wheels refurbished. Having recently noticed a slight loss of coolant, which is down to the offside front radiator, I’ve decided to replace both sides. That leads to my question, what coolant, as it takes 22.5 litre? The genuine Porsche coolant is very expensive, G30 is good value, but is it as good? After going to a well known parts distributor their trying to tell me Viaco G12+ purple is the recommended product for my car. Having not heard any mention of this in any of the forums, I find this hard to believe. Again I apologise in advance for going over old ground, but I’m having them fitted next weekend and don’t want to make a decision I’ll regret later. Simon

POST 2Original post

Comma G30 Xstream is Porsche Approved (1996-2009 cars), and very good quality. That's what I would use. I can't comment on the Viaco G12+, as I have no experience of it.

POST 3 / ORIGINAL POSTEROriginal post

Thanks for your advice Richard, I’ve ordered the G30??

POST 4Original post

I used Comma G30 after my intermix problem from 2 years ago. I bought the concentrated antifreeze and pre-mixed with distilled water to limit impurities in the coolant.
