Engine Fan Blade
Verify that there is enough fan blade
clearance with the fan shroud. Around the
fan shroud, the recommended distance is 1
in. (25 mm) from front edge of any fan
blade-to-radiator side member. Minimum
clearance is 3/4 in. (19 mm).
•
Rear edge of any blade must be no
closer than 3/8 in. (9 mm) to the
nearest engine component. If this
cannot be obtained, the fan spacer
or fan is not correct.
• The leading edge of any fan blade
must be 1 in. (25 mm) from the
inside edge of the shroud.
Poly V-belt and Fan Drive Belt
Removal
Engine belt replacement procedures for
poly v-belt and fan drive belts.
Perform these maintenance procedures
according to the Preventative Maintenance
Schedule.
1. Disconnect the electrical ground
wire from the battery.
2. Reach between the fan blades and
remove the fan blade mounting
bolts using a 9/16” socket to
remove the mounting nuts.
3. Place a flex-bar with a 15 mm
socket on the fastener securing the
automatic belt tensioner's roller, as
shown in the image.

-belt and Fan Drive Belt
4. Rotate the flex-bar as shown in the
diagram to relieve belt tension.
5. With the belt tensioner pressure
relieved, remove the poly V-belt
from the pulleys.
•
The tensioner can be
temporarily blocked with a
0.16-0.2 inch (4-5 mm) thick pin
(bore). This facilitates removal
and installation of the poly V-
belt.
6. After removing the belt, carefully
allow the belt tensioner to spring
back to the stop (if it had not been
temporarily blocked).
7.
Inspect the pulleys for damage,
rust, and grease deposits. Clean or
replace as necessary.
Poly V-belt and Fan Drive Belt
Installation
Procedure to install poly v-belt and fan
drive engine belts.
Follow the steps below to install the poly v-
belt and fan drive belts:
1. Place the new poly V-belt over the
pulleys, making certain the belt
falls into all the belt pulley grooves.
NOTE
When installing the belts do not wrap
belt around the
tensioner until after the
belt has been wrapped around all oth-
er pulleys and idlers.
2. After installing the belt, carefully
allow the belt tensioner to spring
