What is the coolant temperature indicator system and Coolant Temperature Sensor and how does it work on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?

The coolant temperature indicator system comprises a dashboard-mounted gauge and an engine-mounted sensor, which also informs the fuel and emissions systems. If overheating is indicated, check the coolant level and sensor operation. A defective sensor should be replaced. If the sensor is functional, the temperature gauge should be assessed by a dealer using a scan tool, as the onboard computer processes the data.

How do I remove the engine coolant temperature (ECT) sensor on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?

Drain the cooling system below the ECT sensor level. Disconnect the electrical connector from the ECT sensor. Unscrew and remove the ECT sensor. If you're installing the old sensor, wrap the threads of the new ECT sensor with Teflon tape and the threads of the new sensor should already be coated with sealant. Installation is the reverse of removal. Be sure to tighten the ECT sensor to the torque specifications. Refill the cooling system.

GMC Sierra Coolant Temperature Sensor

The Coolant Temperature Sensor in GMC Sierra trucks helps to measure the retardant temperature, which guarantees that the engine will run proficiently. This sensor affords important info to control the functionality and efficiency of the engine. The GMC Sierra being a collection of automobiles within a given period, it has adopted several GMC Coolant Temperature Sensors that are essentially of one use but may vary in design or technology. Such variations could be variations in sensitivity or in the speed with which the engines respond, and these could in turn determine the extent to which the temperature information being reported to the engine control unit is accurate. In general, the Coolant Temperature Sensor is essential to check the health and the performance of the engine.

Each OEM GMC Sierra Coolant Temperature Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
