7.18 Radiator / Oil Cooler
Cleaning Procedure
The radiator and oil cooler
must be clean to ensure prop-
er operation. Engine and
hydraulic system overheating,
damage and even failure can
result if the radiator/oil cooler
is not kept clean. A pressure
washer or compressed air
nozzle work well to blow
debris clear of the fins in the
oil cooler and radiator.
To clean radiator / oil cooler:
1. Make sure the engine is
off, and cool, and that the key is removed from the ignition dur
ing radiator/oil cooler cleaning procedure.
2. Thoroughly clean radiator/oil cooler with a pressure washer or
compressed air. Wear any appropriate safety clothing. Direct
spray forward through the cooler as shown. (fig. 7.18-1 & 2)
Note: Make sure water nozzle is at least 30.5 cm (20.3 cm for air)
from the cooler and that the spray is directed straight through the
cooler or the cooling fins may be damaged (bent over) which will
decrease cooling performance.
Note: If hydraulic oil or engine coolant temperature lights illuminate
during operation, clean coolers more often.
Note : In dusty applications check and clean the coolers and chassis
often to avoid overheating and prevent fires.
7.19 Engine Coolant Change Procedure
1. With the engine off and cool and the key
removed from the ignition, remove the
lower rear screen and raise the hood.
2. Open the radiator drain valve (1) and allow
the coolant to drain into a catch container.
3. Close the drain valve, then add coolant
(with SCA additive) into the radiator through the fill cap until full.
4. Warm the engine to operating temperature, then turn the
engine off, remove the key and allow the machine to cool.
5. Check the coolant level, and top off (repeat steps 4 and 5
until all air has been purged and the level is full when cold).
