If your 93 Chevy is still overheating after you have replaced the thermostat what should you check next?

Has the rad ever been flushed? Try that if there is no indication of water pump failure (leaking or venting coolant from pump.)

Check your coolant levels and make sure it is up to level and decent looking...Coolant (in this case) should be a nice Lime green. Engine Thermostat is probably the most likely cause of overheating...It should be replaced if you haven't already.

Not sure if by your question you mean the thermostat opens slow and the engine overheats or if you mean the engine takes a long time to warm up. If the engine is overheating, more than likely the thermostat is stuck in the closed position and needs to be replaced before engine damage is caused because of overheating. If the engine is taking a long time to warm up, the thermostat is probably stuck in the open position and has to be replaced so the engine can reach its normal operating temperature in a shorter time.

The thermostat on a 2004 Chevy Venture is changed by draining the radiator, removing the upper radiator hose, and unbolting the thermostat housing. The old thermostat and gasket can then be removed and replaced.
