Good morning,
Took the coach out a few weeks ago and it didn't develop heat through the dash, and I noticed my gauge wasn't reading consistent like normal. As it is cold I would like to narrow down my search when I go under later this week...
I have had some belt issues (loosening) but I wouldn't think all three are slipping to not spin the water pump. I would assume a heater box problem, but the guage makes me think more to engine. Stuck open thermostat a possibility? (replaced 1.5 years ago). Should I be thinking pump? I did not notice any wobble when I put the new fan clutch on earlier this summer.
I found this thread with good tips on water pump itself

but hoping for broader input.
Thanks,
Tyler
