RedDOT Heater Valve to suit R6521P AC/Heater Unit - RD146040P

Heater Valve Taps are an important part of any climate control system, regulating the flow of coolant to the heater core. A malfunctioning heater valve tap can prevent heating of a vehicles interior. When performing cooling system repairs you should also consider the heater circuit, which includes the heater valve tap, heater hoses and heater core. This system will need to be maintained just like the cooling system for optimal performance and efficiency.
