How to replace the Heater Control Valve on GMC C3500?

Draining the cooling system should be the first step before heater water valve replacement. The first step in this process requires removal of the access panel nut which is located near the pollen filter along with the access panel itself. Begin the replacement by disconnecting hoses as well as the vacuum hose and remaining clamps from the hot water flow control valve before proceeding to remove the valve. Follow the installation process by putting the new hot water flow control valve into position then reconnect all hoses followed by hose clamps and vacuum hose. Replace the access panel and attach the access panel nut especially until it is fully seated and not damaged. Finally, fill the cooling system.
