Drive and Coolant Pump Drive
Removal
1. Remove the poly V-belt from the
fan and coolant pump drive as
described in “Poly V-belt and Fan
Drive” “Removal”.
NOTE
Removing the fan blade is not nec-
essary if only the accessory belt is
removed. After removing the fan
drive belt from its pulleys the acces-
sory belt can be removed over the
fan blade.
2. Next, place a flex-bar with a
15 mm socket on the alternator
and air conditioning compressor
drive belt tensioner roller fastener
as shown. Move the bar in the
direction shown to relieve pressure
on the belt tensioner.
3. 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.
4. After removing the belt, carefully
allow the belt tensioner to spring
back to the stop (if it had not been
temporarily blocked).
5. Inspect the pulleys for damage,
rust and grease deposits. Clean
or replace as necessary.
