a. Heater Assembly Removal
1. Park the vehicle on a firm, level surface. Level the
vehicle, ground the attachment, place the travel
select lever in the (N) NEUTRAL DETENT position,
engage the parking brake switch and shut the
engine OFF.
Note: For vehicles equipped with air conditioning,
before the heater assembly can be removed, the air
conditioning hoses and electrical connections must be
completed by an authorized air conditioning service
technician. A technician will also be needed to restore
the connections when the heater assembly is installed.
2. Unlatch and open the engine cover. Allow the engine
to cool. Draining the cooling system while the engine
block is hot can cause cracks in the engine block.
3. Place a suitable container beneath the radiator drain
plug (1) or petcock. Slowly turn the radiator cap (not
shown) to the first stop, and allow any pressure to
escape.
4. Remove the radiator cap. Place a funnel at the base
of the radiator to channel the drained coolant into the
container. Open the radiator drain plug (1) or
petcock and allow the coolant to drain. Replace the
drain plug, or close the petcock.
WARNING:
Hot coolant can cause
severe burns or eye injury. NEVER remove the
radiator cap while the engine is hot. The
cooling system is under pressure. Wear
protective clothing and safety glasses.
