What It Helps Address

• Incorrect coolant temperature readings

• Erratic gauge or engine management performance from a failing sensor

Installation Notes and Tips

Verify the sensor location before ordering. Fitment includes radiator, upper, and N/A positions depending on the vehicle, and the connector style must match the existing harness. Confirm the oval female plug-in connector, 2 blade terminals, and push-in mounting style against the original part. For best results, compare the old sensor’s shape, terminal layout, and mounting depth before installation. Standard Ignition TX375 is listed for specific GM applications only, so use the vehicle year, make, model, and position details shown here to confirm the correct application.
