What kind of coolant for 997S?

 

According to my dealer, use only factory coolant in the 997 because it's designed to be permanent. The service writer claimed that damage from use of non-Porsche coolant would not be covered under the warranty. I needed a quarter cup-ful to top mine off and I had to buy a gallon (at $32 a gallon) because they discontinued the pint bottles.

 

Here are some other responses whrn I asked the question.

You can buy a gallon of 50/50 PEAK Lifetime for less than $10. 100% compatable with what is in there.

 

Porsche brand

 

I remember reading something that it is against the law for a car company to insist on buying there branded fluids and void the warranty if you don't. This came up either somewhere on this site or the rennlist site.
I read almost everything on these sites about what coolant to use and I came up with either Dexcool Havoline Ext Life, Peak Long Life 50/50, or Prestone Ext Life. If all you need to do is a little topping off....distilled water is okay.
