PART 8: MAINTENANCE AND SERVICE

CAB HEATER-AIR CONDITIONER

(R05/10)

• Check the evaporator core and condenser core for

debris restricting air flow. Clean if necessary. Small
particles may be removed with compressed air blown
through the core in the opposite direction of normal air
flow.

WARNING! 

Wear eye protection any time you

blow compressed air. Small particles blown by
compressed air could injure your eyes.

• Check all hoses for kinks, deterioration, chafing, and

leaks. Adjust kinked or chafing hoses to eliminate
restrictions and prevent further wear.

• Check all components and connections for refrigerant

leaks. If you discover a leak, don’t try to tighten a con-
nection. Tightening a connection may cause a worse
leak. Have a qualified technician correct the problem.

NOTE: A leaking evaporator or condenser core

cannot be repaired; it must be replaced.

• Have the air conditioning system fully inspected annu-

ally by your dealer.

Special Precautions

WARNING! Excessive heat may cause your air
conditioning system to explode which may
result in death or personal injury. Never weld,
solder, steam clean, or use a blow torch near
any part of the air conditioning system. If a
refrigerant leak develops in the presence of
excessive heat or an open flame, hazardous
gases may be generated. These gases may
cause illness or death. If the system is leaking
refrigerant

• Stay away from the hot engine until the

exhaust manifold has cooled.

• Don’t permit any open flame in the area.

Even a match or a cigarette lighter may gen-
erate a hazardous quantity of phosgene
gas.

• Don’t smoke in the area. Inhaling gaseous

refrigerant through a cigarette may cause
illness.
