Hey guys i just finished rebuilding one of my friends sr's Its a redtop in a s14 silvia rhd. Now the problem is when the car idles it does not build temp. But while driving it starts too. The temp gauge will go about 2/3 up. During the build i made sure all the ports in the block were cleaned out. The water pump is good. There is a new radiator in it as well. I thermostat was sticking so i gutted the theromostat. The clutch fan wasnt locking up properly so i changed that as well. There is no restrictions in the cooling system. Is it possible by me pulling the thermostat that it can cause this to overheat in that kind of fashion. Your input would be greatly appreciated. Also the heater core has been bypassed.
