This video will demonstrate how to drain the cooling system and replace the thermostat along with the coolant temp sensor and refill the cooling system on the 1988-2000 GM 5.7 Vortec motor found in the K & C Series Chevy and GMC Trucks, Suburban, Tahoe, Yukon, Express, Savana, and Cadillac Escalade. All the replacement parts can be purchased from Amazon and I have provided links to them below.
