Has the rad ever been flushed? Try that if there is no indication of water pump failure (leaking or venting coolant from pump.)
follow top raditaor hose to engine. Should be right there.
The 1992 Chevy 3500 temperature sensor is located on the front of the engine. The temperature sensor will be in the vicinity of the thermostat housing.
(ESC) Electronic Spark Control Module on 89 Chevy should be mounted near the throttle body of the TBI. May have letters HKR stamped on it.
make sure the car isn't over heating. it can over heat without showing on the gauge or light. check your coolent fluid level, if it's ok make sure the thermostat is ok. have your heat sending unit replaced as it can be faulty also. another problem can be the computer putting it out of time when it is warmed up. have it checked as soon as possible because these small engines can't take much overheating.
Have you tried replacing the tensener pulling, it has a bearing inside it that should allow the roller to spin. They are not very expensive.
brilliant, the thermostat is backwards
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.
Need to know the year and engine size so I can help you. NEUTZ air lock? system blockage? is the thermostat installed correctly? 6.0 Engine Yes on the thermistat installed correctly
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 top radiator hose is above the thermostat. If the top radiator hose is hot, the thermostat is opening. The thermostat is not the problem. Perhaps the radiator is clogged up or the water pump is bad. Look elsewhere.
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.
thermostat sticking closed then snapping open
its either the water pump or thermostat take it to a shop if you can that pump is a nightmare to change
the thermostat will be under the THERMOSTAT HOUSING, which is where the TOP radiator hose fits on ie(radiator to thermostat housing) this keeps the engine at an OPTIMUM temperature BUT can be A cause of OVERHEATING IF malfunctioning
I had mine replaced and the cost of the thermostat and housing was $48.67 without the cost of labor.
Thermostat.
Overheating or engine does not get warm enough. Replace any suspect thermostat. You can test one, but as you have to remove it to do so, just replace it.
