The water temperature switch in heavy-duty and truck applications is a vital component that monitors the engine's temperature and prevents overheating. This switch detects the temperature of the engine coolant and sends a signal to the vehicle's computer system to adjust the engine's performance accordingly. A malfunctioning water temperature switch can cause the engine to overheat, leading to severe damage and costly repairs.

The water temperature switch is typically located on the thermostat housing, but the exact placement may vary depending on the make and model of the vehicle. Some heavy-duty and truck applications may have the switch located on the engine block, cylinder head, or other components of the cooling system.
