2003 Toyota Tundra Parts Questions & Experts Answers

• Q: How to service and repair the Heater Control Valve on 2003 Toyota Tundra?

  A: A heater control valve maintenance operation begins with emptying engine coolant from the radiator without completely draining the coolant tank. When disconnecting the water valve control cable from the water valve it is essential to perform cable adjustment steps during the installation process. The water hoses must be detached through hose clip claw manipulation with pliers until the hose slides out and then remove the hoses. To properly install the water hose insert it until the second pipe ridge onto the heater radiator then until the valve end of the water valve pipe before tightening the appropriate hose clip. Complete the installation by undoing the bolt and water valve before following the opposite steps of removal.
