check thermostat or water pump, I've had both problems before and it will cause the car to overheat. The temp sensor is on top of the engine right in front of the spark wires. It go's down into the engine.
coolant temperature switch turns on the fan, if the fan isn't running the car's overheating...it's a sensor mounted in the coolant line that detects coolant temp.
I dont understand, is your car overheating or do you think your switch is overheating? Switches do not overheat, if they become hot to the touch there is a grounding problem which would have most likely blown a fuse at some point.

Common causes of overheating are; defective ( stuck closed ) thermostat, low coolant level, bad water pump, failed electric fan relay, failed electric fan, failed electric fan thermo switch, blockage in coolant lines or radiator or blown head gasket ( check oil dipstick for coolant in your oil pan ). The Temp sensor does not prevent overheating, it just senses how hot the engine is. Try changing the coolant fill tank screw on cap,that is what mine was.
fan motor could be grounding internally Unplug the fan switch and ground the wire if the fan stops replace the switch. If not you have an open between the coolant sensor (switch) and the relay. The coolant sensor for the fan is not the same sensor for the computer/fuel injection.
The ECT or the Engine Coolant Temperature Sensor is a switch. This switch is located on the bottom of the radiator in the 1996 Camry.
There is no such thing as a: temperature switch, on your Ford focus, the coolant temperature sensor is located on the front of the engine.
yes...fisrst you need to check if the temp sensor is working. If this has an electric fan, check the relay and the fan motors. or when my 97 4.6 v8 was overheating, it was leaking coolant from the head gaskets.

Causes of overheating: Low/no coolant; cooling fan relay switch/sensor faulty; cooling fan motor faulty; thermostat stuck in closed position; water pump faulty.
