The coolant temperature sensor monitors coolant temperature and then displays the measurement to the vehicle’s occupants. The engine can be in danger of damage if it operates at too high of a temperature. The coolant temperature sensor is critical to many PCM functions such as fuel injection, ignition timing, variable valve timing, and transmission shifting. Each Coolant Temperature Sensor is environmental and 100% functional tested to ensure optimum performance and durability out of the box.
Glass fiber-reinforced plastic polymer connector ensures excellent dimensional stability and proper mating connector fit across temperature extremes
Precision-machined brass housing maximizes thermal conductivity between sensor body and coolant
Tapered pipe threads with pre-applied sealant ensure tight, leak-free fit
Grease applied inside brass housing facilitates heat transfer with thermistors
100% factory-tested for proper resistance value at specified temperature
