Porsche Enthusiasts Club Forum

Has anyone used the Waterless Coolant (Evans) which is being promoted by Wheeler Dealers?
Not really sure if it does what it says on the tin and so much contradictory comments on other owner groups forums.

I would not bother with it.

Use the proper coolant mixed with the right amount of distilled water, a 50/50 mix is good if you are using neat anti freeze, but beware, some anti freeze is pre mixed or is very weak.

Also make sure you use the pink long life anti freeze in a Boxster, you do not need to use the Porsche bottled type, but it does need to be the longlife pink, rather than the old style blue or green antifreeze
