Temperature Sensor (Gauge): Service and Repair
WATER TEMPERATURE SENDING UNIT REMOVAL / INSTALLATION
Never remove the pressure relief cap while the engine is operating or when the cooling system is hot. Failure to follow these instructions can result in
damage to the cooling system or engine or personal injury. To avoid having scalding hot coolant or steam blow out of the coolant reservoir when
removing the pressure relief cap, wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it slowly. Step back
while the pressure is released from the cooling system. When you are sure all the pressure has been released, (still with a cloth) turn and remove the
pressure relief cap. Failure to follow these instructions may result in personal injury.
1. Disconnect the water temperature sender wire.
2. Remove the water temperature sender unit.
3. Install in reverse order of removal.
Note: Prepare the new water temperature indicator sender unit for installation by applying pipe sealant or a small amount of electrically
conductive sealer to the threads.
