	Steve installs the a/c fan.

• First, loosen and remove the stock water pump pulley and belt so that the new a/c compressor system can be installed.

• Remove the lower crankshaft pulley so that it can be replaced with one for the new compressor drive belt.

• The new crankshaft pulley goes into place and is secured with new bolts.

• Tip: As always it's important to thread bolts in by hand first before using a wrench. Then the bolts are tightened down evenly, going through the bolt sequence several times.

• Next remove the bracket and water pump bolts as needed to install the new pulley & compressor bracket.

• The new pulley and compressor bracket goes into place.

• The bolts are installed, along with spacers and washers and the bolts are tightened down.

• The stock water pump pulley and the new high-volume fan goes into place and is secured with new bolts.

• Before installing the compressor, reinstall the original fan belt, slipping it over the fan and onto the pulleys.
