I have a 1999 chevy cavalier it has 95,000 miles on it and for the past 5 months i've had on going issue with my car running hot. I have had the thermostat changed three times, a new water pump, upper radiator hose replaced, a new sensor installed. Also the serpentine belt and lower radiator hose check does not need replacing so i'm told. Oh and i've also had a pressure check done as well and the radiator has been flushed although I don't think this was done properly. What else can I do before I go out of my mind.

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: Thermostat, Pressure test the Rad. Cap, Clogged radiator, Fan clutch, Radiator electrical fan, collaspe hoses, water pump.
