Step 2 Leave serpentine belt in place and loosen the crankshaft pulley and waterpump pulley bolts.

Step 4 Remove belt, carefully noting the routing for reinstallation once pulleys are installed.
Step 5 Remove pulleys from vehicle and simply reverse the process to install the BBK pulleys. Install all of the pulleys finger-tight, then install the belt to tension pulleys while tightening to factory torque specs.
Step 6 Carefully follow the belt routing to ensure that the belt is tracking properly. It is very easy to incorrectly install the belt with one groove off a pulley—this would destroy the belt immediately!

These guys are great! Customer service is absolutely top notch. Their pricing points are spot on and every month they off some sort of special on multiple parts. Not only that but the staff will educate you on the parts and their customer reveiw option of every part has been a huge help in determining the validity of each part you buy.
