Ok, haven't been able to get heat to my 5 heaters.
Ran engine for 45 minutes this morning, temp gauge stays down at the 110° mark. Reservoir can above radiator is cool to touch. Removed radiator cap and no pressure was built up. Antifreeze was bright green and cool to touch.
Note: I drove to camp site a few weeks ago and temp never got above 140° (think thermostat might be removed?)
Anyway, found one gate valve that was open and a Gould Valve... There's also a console switch labeled Thermo Control that I have not learned what it operates, so now I'm guessing the Gould Electronic Gate Valve, but haven't multi-metered it yet... It's 24° outside. Did not find a fuse labeled Thermo Control, so I'll have to chase it out and find fuse or relay.
I didn't/don't have a grill cover over my radiator. There are no valves to operate around the driver's area.
I can follow the green heater hoses from the gate valves, passing in front of radiator, then entering the firewall behind my fuse panel door on front of bus, pretty much inline with where the first heater is under driver's seat, trimmed out with sheet metal.
Does all this sound about right?
What steps would you take to get heat to heaters?
similar to this, but I only have 2 wires, it appears
