I have an 02 wrx. It was recently in an accident on the passenger front. I just finished up the body work and ready to get her back on the road and it's overheating. I replaced the thermostat and still overheating. It's really weird. It acts fine and then shoots up past the red. I fill it up with antifreeze and replace the cap back on the turbo coolant and it creeps down and then shoots up again. IDK what to do or what it is. Been told possibly water pump. Just replaced radiator 5 months ago. Anybody know whats up?
