Engine Coolant Temperature Sensor: Notes
WARNING: This page is about a different car, the 2003 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Allow sufficient time for engine to cool before removing ECT sensor. A hot engine may cause an excessive coolant loss or a personal injury.
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 drain. Ethylene glycol antifreeze is very toxic. Disposing of ethylene glycol into sewer system or ground water is both illegal and ecologically unsound.
