I have a 2005 wrx, and for the past couple days, i've been spraying a lot of coolant. It appears to be coming from the passenger side, at the top, and is spraying hard enough that it's spraying the boost controller. I can't see any definitive place that it's coming from, but it appears to be coming from maybe where the plastic tank is attatched. Any ideas?
You cant tell where it is coming from? Take the 2 bolts out of the tank and lift it up a little then maybe you can tell where it coming from. If that dosent work then take it to a shop and have it pressure tested.
