The engine is equipped with an engine block heater
(Fig. 9 -93, 1) that can be plugged into a standard
110/120V A.C. grounded outlet to heat the engine coolant.
When temperatures are below 10° F (-12° C), the block
heater should be used to aid in starting.

1. Level the vehicle, ground the attachment, place the
travel select lever in (N) NEUTRAL, engage the park
brake switch and shut the engine OFF. Remove the
ignition key.
2. Secure accident prevention tags to the steering
wheel and ignition key switch. (Refer to Section 1.5,
“Accident Prevention Tag Usage.”
)
3. Disconnect the negative (-) battery cable at the
negative battery terminal.
4. Unlatch, unlock and open the engine right and left

plug (Fig. 9 -94, 1) or petcock. Slowly turn the
radiator cap (not shown) to the first stop and allow
any pressure to escape. Remove the radiator cap.
Figure 9-94 Drain the Engine Coolant.

the drained coolant into the container. Open the
radiator drain plug (Fig. 9-94, 1) or petcock and
allow the coolant to drain into the funnel. Close the
radiator drain plug or petcock.
7. Transfer the coolant into a properly labeled container.
Dispose of properly if coolant needs to be replaced.
8. Remove plastic retainer (Fig. 9 -93, 5) from around
engine block heater element (6) and 110-volt cord (2).
