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.
