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 switch. (Refer to Section 1.5,
“Accident Prevention Tags.”)
3. If the vehicle has one battery, disconnect the
negative (-) battery cable at the negative (-) battery
terminal (1).
If the vehicle has dual batteries, disconnect both
negative battery cables from both negative (-) battery
terminals (2).
4. Unlatch, unlock and open the engine right and left
engine access doors. Allow the engine to cool before
proceeding. Draining the cooling system while the
engine is hot can cause cracks in the engine block.
5. Place a suitable container beneath the radiator drain
plug or petcock (3) on the bottom, right side of the
radiator. Slowly turn the radiator cap (not shown) to
the first stop and allow any pressure to escape.
Remove the radiator cap.
6. Place a funnel at the base of the radiator to channel
the drained coolant into the container. Open the
radiator drain plug or petcock (3) 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 (4) from around engine
block heater element (5) and 110-volt cord (6).
9. Using a 29 mm socket, remove heating element from
engine block.
WARNING:
DO NOT attempt this
procedure when the engine is hot. Wait for the
engine, muffler and tailpipes to cool down
before proceeding. Failure to do so could result
in severe burns.
