i just picked up a 91 gsx and on the ride home it was over heating. first i thought it was just an air pocket in the system since it was a fresh rebuild like 500 miles and its just been sitting. so i flushed the system and check the thermostat. i ended up just removin the thermostat and seein if that would fix the problem and it hasn't.. right now the heat isn't hooked up in the car would that be affecting this problem? other then this issue the cars running awesome so anyone have some suggestions??
