NOTE: Use the hose attached to the petcock to allow draining directly into a
container.

NOTE: On vehicles equipped with a cab heater option, a shut off valve is
installed at the engine inlet. Disconnect hose from shut off valve to drain the
heater.

properly.
7. Reconnect line to bottom of overflow bottle and close petcock on
the radiator. Reconnect heater hose.

water. Total System Capacity is 4 gallons (15 liter). Add coolant to
overflow bottle until bottle is about 1/2 to 3/4 full. This “overfilling”
will compensate for any air in the cooling system.

then shut OFF the engine. While the engine is cooling, check for
leaks.
11. Allow engine to cool to ambient temperature. Check radiator cool-
ant level and top off completely. Replace radiator cap.

overflow bottle. Close and lock all access doors.
