1966-70 Dodge, Chrysler & Plymouth B-Body Factory A/C Heater By-Pass Valve

January 5th, 2011

New from Classic Auto Air – Mopar B-Body Heater By-Pass “h” valve.  Fits 1966-70 Mopar B-Body & most 1965-68 C-Body cars with factory a/c.

Installs on the heater coil as shown below.  The valve’s main function is to regulate whether all or only half of the heater coil is used, based on dash control settings.

To prevent leaking hot water from inside the car and insure that your heater system is functioning correctly, it should be replaced anytime the heater coil is replaced.
