Product Details

Standard Ignition TX110 is engineered to provide accurate coolant temperature input to the engine control system. That signal supports proper fuel delivery, idle strategy, and cooling-system monitoring. This part cross-references Nissens 73979 for the same application. TX110 is a practical replacement choice for Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500, GMC Sierra 2500 HD, and related GM applications where precise coolant temperature reporting matters.

What This Sensor Helps Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough cold operation caused by inaccurate temperature input
• Cooling fan or engine management concerns tied to faulty sensor data
• Check engine light conditions related to coolant temperature sensor faults
• Driveability issues on Chevrolet Silverado and GMC Sierra applications

Installation Notes and Tips

Verify connector shape, terminal count, and screw-on mounting style before installation. Inspect the harness connector for corrosion, bent terminals, or damaged locking tabs before connecting TX110. Confirm the cooling system is at a safe temperature and follow the vehicle service procedure when removing or installing the sensor.
