Question about 1985 Pontiac Grand Prix
If I let it sit for an hour or so I can then drive it short distances.
I have been told maybe the oil pressure is bad, so I had it checked
and changed the oil and it still overheats. It does not leak antifreeze.
I have also drained and refilled with new antifreeze. It is my first car and I am not mechanically inclined but want to learn what I can to save money on repairs. Can you offer any advice or suggestions as to what to check next.
Did you put a new thermostat in, and did you flush the radiator when you changed the coolant? If not best do that, thermostat might be stuck closed or radiator could have sediment build up and its not cooling the coolant properly. It also could have a bad waterpump and its not pumping the coolant thru the system. If after all that, and it don't fix the overheating problem than i am afraid the problem is internal like head gasget or maybe cracked head.
