pewble

Yea so i changed my radiator and my hoses and my thermostat, i used a "scant" thermostat that was rated at 85c.. LOL that was just wrong. so i bought a oem thermostat yesterday and it seemed to work ok for like 40 minutes. then it started to overheat again when i pushed the car for the second time. ( i beat a jetta beforehand)... so now im not sure if it still overheats and sure woulndt understand why if it does again. it worked on my way to work today... you think its residual air bubbles or what?
