Is their a special thermostat that is used with the cab heat
option. I am having trouble getting heat out of the heater
even after the RTV operating for over 1 hour. I have checked
to see that the water hose valve is open.
mine works fine right down to 15 degree f so far. In fact it gets so hot I have to turn it down..
Takes about 10 minutes top for the engine to warm up and the heat is furnace hot..
