Kingdom of Callaway - Fulton, Mo 65251 | I have a Cat Challenger 55 and the heat won't come on. The AC worked fine all summer, and the fan still blows powerfully, so I don't think the heater core is externally clogged. The heater hose valves are open, but the hoses stay cold so it isn't circulating. The hot/cold dial feels like it works when you turn it.
How do I access the heater core area? From inside the cab ceiling? Or does roof come off on the outside? |
