Engine Coolant Temperature Sensor: Notes
WARNING: This page is about a different car, the 2003 Pontiac Montana, 2003 Oldsmobile Silhouette, and 2003 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
To avoid being burned, do not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if radiator cap or surge tank cap is removed while the engine and radiator are still hot.
CAUTION:
Use care when handling the engine coolant sensor. Damage to the coolant sensor will affect the operation of the fuel control system.
NOTE:
Recover and store used coolant in a used coolant holding tank and submit the used coolant for recycling on a regular basis. DO NOT pour used coolant down the drain. Ethylene glycol antifreeze is very toxic. Disposing of ethylene glycol into the sewer system or ground water is both illegal and ecologically unsound.
