HEATER HOOKUP INSTRUCTIONS
Pressure/Hot Line to cab heater core;
4.1) With the engine hood opened, drain the radiator by opening the radiator drain plug.
4.2) The pressure-hot hose will be hooked up with the aluminum fitting, one brass fitting,
O-ring washer and a 5/8” hose clamp (Items 8, 11, 12 and 13 on mount kit drawing
4-14563).
4.3) Unplug the electrical sensor and unscrew sensor fitting that is threaded into the water
pump, near the underside of the thermostat location. Set the sensor and washer aside.
4.4) Use pipe seal thread tape or liquid pipe seal compound on all threaded fittings. Install the
aluminum T-fitting (Item 8) with the rubber O-ring washer (Item 13) into the water pump.
Do not over-tighten! When the O-ring washer seats, orientate the fitting so that the brass
hose fitting (Item 11) can be installed easily.
4.5) Install the brass hose fitting (Item 11) into the aluminum T-fitting (Item 8).
4.6) Reinstall the electrical sensor fitting and washer into the aluminum T-fitting (Item 8).
4.7) The cab is shipped with two 5/8” heater hoses, hooked up from the factory. The outer
line will be the hot-pressure line (See figure 4-2). Route hose and install onto the brass
fitting (Item 11), securing it with a 5/8” hose clamp (Item 12). (See figure 4-1).
