Apparently 68 Chevelles did not have a heater control valve to shut off the water to the heater core. Just the opening and closing of the doors inside the heater and air cond plenum is what controled the temp (I guess). The heater core in my son's 68 started leaking so I disconnected the heater hoses and looped one to bypass the water. WOW! THE AIR CONDITIONER IS FREEZING COLD NOW!!! Has anyone rigged up a heater control valve on their 68 (like maybe on a 70), other than installing a manual shutoff valve in a hose?
Or, was the 68 SUPPOSED TO HAVE a valve, and maybe someone in the past removed it?
