How to test and replace the coolant temperature sending unit on Nissan Maxima?

The coolant temperature indicator system consists of a temperature gauge mounted in the instrument panel and a coolant temperature sending unit mounted on the engine. The temperature gauge sending unit on SOHC engines is located adjacent to the distributor, while on DOHC engines, it is located in the water outlet tube. This is the coolant temperature sensor for the computer on some models. There is more than one temperature sensor, but only one is used for the indicator system. If an overheating indication occurs even when the engine is cold, the wiring between the dash and the sending unit should be checked for a short circuit to ground. If the gauge is inoperative, the circuit can be tested by briefly grounding the wire to the sending unit while the ignition is On, but the engine is not running for safety. If the gauge deflects full scale, the sending unit should be replaced. If the gauge doesn't respond in the test, the temperature gauge wiring circuit should be checked by a dealer service department or other qualified automotive repair facility. If the sending unit must be replaced, it should be unscrewed from the engine and the replacement quickly installed. A conductive sealant should be used on the threads, not Teflon tape. The engine should be cool before removing the defective sending unit. There will be some coolant loss as the unit is removed, so be prepared to catch it. The coolant level should be checked after the replacement part has been installed.
