Hi. I have a 2002 Impreza with the modifications listed below. I am having a problem. My car is overheating, and my heat doesnt work. The heater blows out freezing cold air. I thought it was the thermostat, so I got a zerosports thermostat and it didnt help the problem at all. Doesn anyone know what this can be? My next guess would be the water pump...but is there a way to find out before I take it off?


Ross Racing Pistons, Paeuter Rods, Turbo XS FMIC, Injen CAI, Turbo XS up/down pipe, hks hi-power exhaust, turbo xs u-tec, short shifter, rota subzero rims, engine grounding kit, hks type 1 turbo timer.

How's the coolant level?

Does the heater ever get warm?

Any white "smoke" out of the exhaust?

 

would have to say check the coolent level!

 

My radiator was leaking from the drain plug, I replaced it and it is fine now. Thanks. I got another problem now tho...its posted as the topic..... Help? Help!
