There are two coolant sensors. One for the ECM and one for the gauge or light. The one for the ECM is located on the intake manifold near where the thermostat housing is. It'll be located on the back side of this and a little low. It can be hard to see because of the air intake hose. The one for the switch is located straight back from that one on the rear corner of the block. I think it is a blue or green wire running to it. It will be a single wire unit while the one for the ECM will have two wires....yellow and brown.
What else can I help you with?
What would cause the Temp light to come on in a 91 Chevy Lumina?
could be several things. 1st is the car actually overheating. If so then it could be a stuck thermostat or a bad water pump. If it is not really overheating my bet would be a falty temp sensor. The temp sensor is what actually tells the light to turn on.
