25. Position the A/C compressor belt onto the top of the
crankshaft pulley. Using the provided tie straps, securely
hold the belt onto the crankshaft pulley at the 12 o'clock
position. Do this by feeding the tie straps through the
crankshaft pulley spokes, up and over the A/C compressor
belt and then securely tighten the wire ties.
CAUTION: To avoid damaging the A/C compressor belt,
make sure the belt is above the oil pan flange at all times
during the installation process. The oil pan flange is very
sharp and may cut into the belt if contact is made during the
installation process.
Wire Ties
CAUTION: It is crucial to maintain the belt alignment
with A/C compressor pulley when rotating the crankshaft
pulley. This is done by carefully pulling the belt towards the
front of the vehicle, with your free hand, while rotating the
crankshaft pulley. The belt will have a tendency to skip a
groove if not done so; resulting in an unusable belt.
26. With the A/C compressor belt positioned above the oil
pan flange, slowly rotate the crankshaft pulley clockwise
using a 19mm socket with a long ratchet or breaker bar.
Continue rotating until the tie straps are at the 6 O'clock
position.
27. Remove the tie strap and rotate the crankshaft clockwise
1 full rotation to verify the A/C compressor belt has correctly
seated onto the crankshaft and A/C compressor pulley.
Inspect the belt for any damages before proceeding.
