Installation Instructions for 99-04 Saleens
NOTE to 2002 Saleen Owners: Please read the amendment for 2002 models (listed in the drop down menu below) before beginning installation.
Step 1:
Remove the three bolts shown below. They will need to be relocated in order to install the bracket.
Step 2:
Loosen and remove the belt from the smooth pulley.
Step 3:
Use the new bolts and spacers to attach the bracket to the engine. Install the two bolts and spacers indicated below first.
Step 4:
Line up the belt with the pulley and install the last bolt and spacer.
Step 5:
Snug up the bolts and pull the bracket up and to the left so that it lines up the pulley and belt. Once everything is lined up, tighten the three bolts. Put the belt back on by pulling the tensioner up and slipping the belt back over the smooth pulley.
Step 6:
Remove the bolt from the thermostat housing and install the piece from Step 1.
After the bracket is mounted, the belt should be in the middle, to the backside of the pulley.
On some Series IV’s the belt may not line up in the middle of the pulley. To make it line up you will need to use the enclosed washers.

Important Amendment for 2002 Saleens
If your Saleen is a 2002, I will need to know what size bolt to include with your system. Ford changed their bolt size on April 15th, 2002 from a 10mm to an 8mm bolt. The bolt is located on the driver’s side and has a stud sticking out of it, next to the valve cover. Pull it out to determine if it is a 10mm or 8mm threaded bolt before calling to place your order.
If you have already ordered the system, you will need to remove the stud and the bolt to be sure they are the same size.
Once the plastic piece is loose you should go ahead and relocate it to the thermostat housing. Remove the bolt on the thermostat housing and mount the plastic piece.

the pulley facing the engine.

With the bolt holes lined up, you will install the two bolts you pulled out of the tensioner. The third provided bolt goes through the bracket/spacer. Make sure that both washers are on the outside of the bracket. Tighten up the two tensioner bolts first and then tighten the bracket/spacer bolt.
