Hi all and merry Christmas, can anyone tell me type and amount of coolant needed for 2004 forester 2.5 sti. Googled it but it's a minefield. Thanks.

 

Try Opie Oils
I've always found them good.
Usual disclaimer applies

 

Problem is some of the additives used in antifreezes in the 90's and early 2000's are no longer available (probably banned/restricted).

Personal preference is to fully flush cooling system with hosepipe until water runs clear; block, heater matrix and radiator etc.

Then use Comma G30 and stick with it. If you use concentrate, Basf recommend to use deionised water although tap water is acceptable. I use a vacuum filler to prevent airlocks and save messing about "burping" etc.

Don't mix brands and/or types, as that's when it starts to look mucky. If you do, full flush and start again.

Cars made before 1998(ish) or where there is obviously copper or brass in the cooling system needs comma G48 or super coldmaster blue as OAT antifreezes don't protect copper/brass.

 

ok, thanks
