I need help locating the heater valves on my Cummins Engine. I called Freightliner and they sent over a cut sheet, but it's still vague to me. From what I can see there are 3 valves that could come into play...two are in line with the red hose. Then there's valve that looks completely different and hangs down on the side of the motor, but it's also on the supply hose. The tech thought that possibly the lack of hot air issue we are having could be caused from a valve that is closed. He said that there are two valves, one on the supply and one on the return. He said the supply line is on the top of the engine beside the tranny. The return in on the drivers side by the water pump inlet. I have a "handy" man that might be able to turn these valves if I can locate them. My husband doesn't get home until dark and then can't work on the rig. If anyone has any expertise in this area I would greatly appreciate their input. Thanks
