OIL COOLER
An oil cooler (fig. 14) is attached to the rad­
iator front support on all gasoline engine models
with power steering. The oil cooler is not used on
Diesel engine models with power steering.
The cooler may be removed for repair or re­
placement, if necessary, by disconnecting hoses
Figure 14— Oil Cooler Installed (Typical)
and removing screws which attach it to support
braces.
OIL COOLER MAINTENANCE
At regular intervals, or when operating con­
ditions warrant, examine the cooler for leaks and
bent fins. A damaged or leaking cooler should be
serviced by a radiator specialist or replaced with
a new assembly. Proper repair requires the use of
special tools and equipment as well as provisions
for making proper tests.
If the cooler assembly requires painting, spray
with special radiator paint; do not use paint mixed
with oil, as oil mixed paint will form an insulation
and prevent efficient dissipation of heat.
Occasional external flushing with water, using
an ordinary hose, will help remove dirt, bugs, and
other foreign matter from between fins of cooler.
Water under pressure should be directed from be­
hind the cooler to force dirt out in opposite direc­
tion of its entrance. Direct the water stream against
edges of fins (not sideways) to eliminate danger of
bending fins.
