2002 Toyota Sienna Heater Control Valve Parts Questions & Experts Answers

• Q: How to service and repair the Heater Control Valve on 2002 Toyota Sienna?

  A: The repair process for the Heater Control Valve begins with draining engine coolant from the radiator but the removal of all coolant is optional. The first step for service includes disconnecting the control cable from the water valve using proper installation procedures for this component. The water valve disconnection starts by slipping pliers into the hose clips' claws before moving the clips along the hoses to disconnect them from the water inlet housing. After unfastening the valve use a tool to remove its accompanying nut. Installation should be performed through the reversal of removal procedures. During installation set the water valve control cable through adjustments to the temperature control dial "COOL" position while placing the water valve control lever at "COOL" and securing the control cable with the clamp. Verify the clamp after pulling the outer cable gently in the given direction.
