Engine Coolant Temperature Sensor for GM Applications
The Standard Ignition TX66 engine coolant temperature sensor is built for accurate coolant temperature signal output and dependable connector fit. It uses a brass housing for efficient heat transfer and a glass fiber-reinforced plastic polymer connector for stable mating across temperature changes.
- Direct attachment method for straightforward replacement
- Brass sensor housing to improve thermal conductivity
- Glass fiber-reinforced plastic polymer connector for dimensional stability
- Female round plug-in connector with 3 male pin terminals
- 12-volt electrical specification
- Factory-tested for resistance value at the specified temperature
Detailed Product Overview
Standard Ignition TX66 is an engine coolant temperature sensor used to report coolant temperature to the vehicle’s engine management system. Accurate temperature input helps the system manage fuel delivery, idle quality, and cooling strategy. The brass housing and internal grease support heat transfer between the coolant and the thermistor element, while the connector design helps maintain a secure electrical connection. This part cross-references Beck/Arnley 158-0743 for the same application. The TX66 is a direct replacement choice for vehicles such as the Buick Century, Pontiac Grand Prix, and Chevrolet Lumina when the original sensor needs service.
What It Helps Address
- Incorrect coolant temperature readings
- Hard starting when the engine is cold or hot
- Rough idle caused by inaccurate temperature input
- Cooling fan control issues tied to sensor signal errors
- Check engine light conditions related to coolant temperature circuit faults
Installation Notes and Tips
Verify connector style, terminal count, and thread or housing match before installation. Inspect the mating connector for corrosion, heat damage, or loose terminals, and confirm the cooling system is at a safe temperature before removing the old sensor. For fitment, this part fits 1996-2003 Buick Century, 1996-2003 Pontiac Grand Prix, 1996-2001 Chevrolet Lumina, 1994-1998 Chevrolet S10, and 1987-1991 Porsche 944, along with additional listed applications. It also fits 1995-1999 Buick Park Avenue, 1998-1999 Chevrolet Camaro, and 1993-1996 Oldsmobile Cutlass Supreme in the listed configurations.
Quality Assurance
Standard Ignition factory-tests this sensor for proper resistance value at the specified temperature. The connector is made from glass fiber-reinforced plastic polymer for stable fit, and the brass housing is precision-machined to support thermal transfer between the sensor body and coolant.
