How Do You Diagnose and Resolve Issues with a Faulty Coolant Temperature Gauge and Coolant Temperature Sensor on Toyota Tercel?

To troubleshoot issues with the coolant temperature gauge, start by checking the fuses if the gauge is inoperative. If the temperature indicator shows excessive temperature after running for a while, it may indicate a problem. In the case where the gauge indicates "Hot" shortly after starting the engine cold, disconnect the wire at the Coolant Temperature Sensor. If the gauge reading drops, replace the sending unit. If the reading remains high, there may be a shorted wire to the gauge or a faulty gauge. If the coolant temperature gauge fails to indicate after the engine has warmed up and the fuses are fine, shut off the engine. If the gauge still doesn't work, there may be an open circuit or a faulty gauge. For replacement, start by releasing any pressure in the radiator by removing and reinstalling the cap when the engine is cool. Disconnect the electrical connector from the sending unit and apply sealant to the threads of the new sending unit. Unscrew the old sending unit and quickly install the new one to prevent coolant loss. Tighten the sending unit securely and connect the wiring harness. Refill the cooling system, run the engine, and check for leaks and proper gauge operation.
