heater problem

[Wilhelmus Schreurs]

Robert:
Not sure if you have one or not, but in my coach, not only the summer/winter
switch but there is a booster pump as well.
Check the files section, 1984 redrawn diagrams, that might help you.

Robert,

Do you have a winter / summer switch on your bus that controls an assist pump
to help pump the water to the front of the bus.

Subject: [WanderlodgeForum] heater problem



We just completed a 3000 mile trip in our bus and nothing broke or went

wrong the whole way. It was such an awsome trip. So I have decided to

try to fix a situation that has existed since we have had this bus.

There are three heat exchangers in the coach plus the heat from the

dash. Also I just installed the new domestic water heater that has

connections for the engine coolant that I hooked up. Bothe of the rear

heaters work and get really hot, the one under the front sofa blows

almos cold air, the dash blows cold air, and finally the water heater

doesnt have hot water after driving the bus all day.



When I replaced the water heater last week I noticed that in the inlet

for the engine coolant there was a waxy substance that seemed to be

clogging the line at the copper elbow. I cleaned it out and replaced it.



Any ideas on where to start?



I checked at the engine and found three red handle valves and they all

seem to be open
