iator Core
1. Overheating is often caused by bent
or clogged radiator fins. If the spaces be-
tween the fins are clogged, clean them out
with compressed air or water. Avoid
poldng into the spaces with any hard object.
'\
2. If fins are bent, they should be
straightened, but be careful not to damage
the tubes or break the bond between the
fins and the tubes. Check carefully for
possible leaks after completing this work
and before completely rea~sembling the
radiator.
3. Inspect radiator passages for clog-
ging. If this condition is found, the pas-
sages should be cleaned at a qualified
radiator service station.
CA UTION: Never use chemical mix-
tures to stop radiator leaks except as a
temporary, emergency procedure to be
followed by correct servicing at an early
date.
I nspection and Repair
Fan Service
During servicing or repair procedures, in-
spection of parts and assemblies involved
is always an important responsibility of the
serviceman. Generally, inspection is per-
formed after disassembly has been com-
pleted, however, in many cases, time canbe
saved by inspecting parts when they are
being removed.
The fan is mounted on a spindle in the slot-
ted bracket of the engine front cover. It
should be as close to the radiator as pos-
sible without danger of striking it as it turns
within the fan shroud.
1. Check for bent fan blades or damaged
pulley assembly and repair as required.
2. Inspect the fan pulley assembly fornoticeab
side play indicating a wornbearing.
Replace as necessary.
Be sure to check the following items and
perform the servicing or repair that is
indicated.
1. Inspect the radiator for accumulation
of rust or leaks and flush out passages inthe
engine.
2. Check all hoses and if badly cracked,
or dry and hard, they should be replaced.

3. Inspect the fan drive V-belt and re-
place it if it is badly oil soaked, if it tries
to run on its side in the pulleys, if it is
badly cracked beyond the cover layer, or
if its sides are worn so that it will not
drive the fan at the correct speed.
