On a 1996 Pontiac Grand Am I have changed radiator thermostat and it still overheats

Asked by Rhonda Jul 02, 2016 at 02:07 PM about the 1996 Pontiac Grand Am 4 Dr SE Sedan

Question type: Maintenance & Repair

In November I change the thermostat and then it overheated in last month it overheated
so bad then off to the hose I change that both upper and lower hose and it still
overheated so I took it to a mechanic and he replace the whole radiator assembly it still
overheats when I turn on the air condition it goes down when I turn on my heater now it's
skyrockets to the red line which is really weird is it possible that I need to replace the
thermostat since that seems to be where all the problems initially started back when I got
replaced and if it overheated and I had to get a complete radiator assembly in it and it still
overheats is it possible that when it did overheat that new one was defective or bad

Jim, I only have one fan and yes it does come on so I'm guessing my best bet would be the only 2 things left the thermostat AGAIN and the water pump thank you so much I'll let you know how it turns out.
