overheating issue
 

Hi All, just wondering if u cud help me out...I have a V3 Wrx, and the car starts over heating if i take it on boost...but it won't overheat at all if i drive it normally have done like a 50 60 mile trip and the car is fine, but as soon as i take it on boost once or twice the temp will rise up, but when I turn the car off, let it cool down start it again it will be fine. Not sure why this would happen...any advice on this would be appreciated. Thanks

got a similar problem steady speeds its fine higher revs higher temp. i had the sniff test done for head gasket and not that, i done water pump and stat. are you losing water?
