2001 Pontiac grand prix runs hot going up hill n in traffic. New head n thermostat. What do I try next
Did you bleed the air out of the cooling system? This must be done any time the cooling system is drained and refilled. Trapped air will cause overheating. HTH. - Jim
No, but I've been reading on it. Will try later. Thankx
You're welcome. Glad to help. -Jim
