T3 Vanagon Front Heater Valve




If you’re tired of your front heater control valve not shutting off the heat like it should, it’s time for something better. This heater control valve installs as a direct replacement for the stock valve. It’s built from a brass full-port high-temp ball valve that closes completely with zero internal leakage. Being a full-port valve it allows higher coolant flow thru the heater for more heat when you want it. Plus coolant service just got easier, because it automatically bleeds the radiator!


The auto-bleed tube connects to the top radiator bleeder port with a check valve banjo bolt fitting.  It quickly bleeds the radiator of air after a coolant refill. The air is drawn out and flows to the engine by the heater return hose, where it separates in the coolant pressure tank and is purged out of the system. The clear hi-temp tubing shows when the air-bleed is done. No extra steps are required, once installed it works with whatever coolant filling procedure you use, and from then on it continually removes any air that reaches the radiator.


The valve kit includes a new, thicker control cable as well, which must be used because the stock cable wire is too thin and will buckle when pushing this valve closed.


The kit includes:


complete new valve assembly with high-temp purge hose and banjo fitting

check valve banjo bolt and copper sealing washers

new control cable, cable clamp and screw
