Open the engine cover to gain access to the water and
hydraulic coolers.
Ensure that the flow of air through the coolers (1) and
(2) is unobstructed.
Clean a dirty radiator using compressed air or a high-
pressure water jet. Blow or wash the radiator in the
opposite direction to that of the cooling air.
Take care when using a high-pressure water
jet; do not hold the nozzle too near the cooler.
The cooler may otherwise be damaged.
Wear protective goggles when working
with compressed air or high-pressure
water jet.
