If it gets to hot the thermostat wont work. you need to repace it and the gauge will work again.
Replace the Flasher Relay.
only 3 reasons a temp gauge wont work the temp sender is bad the gauge is bad or the wire from temp sender to gauge is broken
check your ground wire to the gauge

sorry its a 94 Mazda b3000 i got a 3.0 out of a ford tarus need to know if it would work to put it in my truck No it wont work because the Taurus is a front wheel drive vehicle and im willing to bet your truck is rear wheel drive so it wont work without a LOT of customizing
A bad fuel sending unit, a fault in the circuitry for the fuel sending unit, or possibly a faulty gauge.
If the temp gauge no longer works then either the gauge itself has failed, the sending unit has failed, or there is a problem in the circuitry.
Can be a blown fuse, defective sending unit, or loose of disconnected wiring. The gauge itself can be bad, but not likely.
