KCM 70Z7 - Clean Radiator;Oil Cooler Cores and Other Cooling System

MAINTENANCE
7-74
Clean Radiator/Oil Cooler Cores and Other Cooling
System
--- every 500 hours or when the core is clogged.

WARNING: When using compressed air pressure [less
than 0.2 MPa (2 kgf/cm
2
, 30 PSI)], wear safety glasses
or goggles.
IMPORTANT: If compressed air with the pressure of more
than 0.2 MPa (2 kgf/cm
2
, 30 PSI) or tap water with high
delivery pressure is used for cleaning, damage to the
radiator/oil cooler fins may result. Keep the nozzle
away from the core surface more than 500 mm (20
inch).
Over the Side Cover
Remove left and right access covers (6) and (7) to clean
radiator (4), oil cooler (5) and intercooler (1) from the
hydraulic driven fan side.
Over the Rear Grille
Open the rear grill to check and clean torque converter
cooler (3) and air condenser (2).
Remove bolts (8) from left and right side of air condenser
(2). Raise air condenser (2) upward. Raise air condenser (2)
until it is secured with catch (9).
Thereby, radiator (4), oil cooler (5), and intercooler (1) can be
checked and cleaned.
If dirt or dust is accumulated on them, cooling system
performance decreases. Clean the radiator/oil cooler cores
with compressed air pressure (lower than 0.2 MPa (2 kgf/
cm
2
)) or tap water. It will prevent a reduction in cooling
system performance.
