Changing coolant 2003 wrx sti
 

Looking at doing a coolant change on my 2003 wrx sti 330bhp was wondering what coolant to use and if any one had a step by step guild would be great cheers

Do a search theres a guide here somewhere. You basically back fill from the turbo water hose to try and not get any air in the system as theres no way to bleed it. I think alcazar was the one who posted the guide so search his posts.

That's great will have a search cheers
