cold engines hve high idles because the pcm is dumping fuel into the motor in order to increase engine operating temperature. when speified temperature is reached, the amount of fuel is decreased an the rpm drops down to the lower idle speed
The temperature light comes on in a 1992 Chevy Lumina when the temperature of the engine reaches the boiling point. The light may also come on if the transmission gets too hot. Usually a leak in the radiator system will cause a loss of fluid and lead to the temperature light, but it could be anything and must be checked.
The 95 Lumina with a 3.1 engine does not have a temperature sending unit. Instead, the dash temp gauge is controlled by the engine coolant temp sensor. This sensor is located on the driver's side, top of the engine.
The temperature sensor is located in the thermostat housing which is on the drivers side of engine, behind the throttle body near the top of the engine
Check actual engine temperature with a thermometer--if in acceptable range temperature sensor or gauge may be defective
1990 Chevrolet Lumina temperature sender is located on the back side of the thermostat housing. The sender has a wire that goes to the temperature gauge.
As long as it is in the "normal" range
yes
behind the engine
depends on the engine size and the transmission type.
should be on right side, front of engine. at upper radiater hose, if not there check the thermostat housing!! on the 3.1 it is located by the ignition control module.
if your engine is at 108c you need to run away
There is no engine block drain plug on a 1996 Chevy Lumina. You drain from the radiator using the plastic plug at the bottom.
