MAINTENANCE
7-53
Check Coolant Level --- daily
CAUTION: Do not loosen radiator filler cap (1)
unless the system is cool. Loosen the cap slowly
to the stop. Release all pressure before removing
the cap.
With the engine cold, the coolant level must be between
the FULL and LOW marks on coolant reservoir (2). If the
coolant level is below the low mark, add coolant to coolant
reservoir (2).
If coolant reservoir (2) is empty, add coolant to the radiator
and then to coolant reservoir (2).
Check and Adjust Fan Belt Tension
--- every 100 hours (first time after 50 hours)
IMPORTANT: Loose fan belt may result in insufficient
battery charging, engine overheating as
well as a rapid, abnormal belt wear. Belts
that are too tight, however, can damage
both bearings and belts.
Visually check the belt for wear. Replace if necessary.
Check fan belt tension by depressing the midpoint between
fan pulley (3) and crank pulley (4) with the thumb. Deflec-
tion must be 8 to 12 mm (0.32 to 0.47 in) with a depressing
force of approximately 98 N (10 kgf, 22 lbf).
If tension is not within specifications, loosen nuts (5) and
(7) for the adjusting plate and alternator bracket. Move the
alternator by bolt (6) until tension is correct. Tighten the
adjusting plate and nuts (5) and (7).
NOTE: When a new belt is installed, be sure to
re-adjust the tension after operating the engine
for 3 to 5 minutes at slow idle speed to be sure
that the new belt is seated correctly.
