    Overheating

    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?

    Describe to me how you burped the car.

    with the engine off i squeezed the top radiator hose and filled the turbo coolant until the fluid stop dropping. i did this for about 15 min. after this i started the car and after it warmed up it ran like normal. but i was told to keep doing it once you start the car. so as soon as i reopened the cap the coolant started gushing out and the temp shot up. I'm not sure if that put more air in the system or i just didn't do it right. i thought the water wont circulate properly if the top isn't on. so i dont know how doing this once it's started can help. please tell me the right way to do this step by step! thanks for your help!!!

    Start again. The part with the car off is also the way I do it. However it seems you capped the reservoir before turning on the car and letting it warm up, so when you uncapped it you lost coolant and gained air.

    This time, let the car go stone cold, and do what you did with the cap off. Then start the motor but leave the cap off still and continue adding coolant and burping until the coolant circulates. Watch your fingers with the fans and hot stuff. Then, after the coolant has circulated and you've got all the air out and it's full, cap it.

    What SD_GR said plus don't rev the engine just let it idle. Also get a funnel that fits snugly into the turbo reservoir this will ensure that if the fluid rises you will not make a mess of the engine bay. Lastly once you have burped the system, might take 40 minutes, put the cap back on while the car is running.
