Installation Notes

1. It is important that you complete all the installation steps before operating the system.

Refer to the Owner’s Manual before operating the system for the first time.

2. Follow all safety precautions for under-hood mechanical work.

3. Use Loctite 242 or equivalent on all engine-mounted fasteners.

4. All hoses, tubes and wires which are re-routed or shifted during installation must be

secured so that they do not contact excessively hot areas or sharp edges. Where

possible, follow the routing instructions in this manual.

5. These installation instructions are intended as a general guide. In some instances, due

to variations in vehicle manufacture or if prior modifications have been made to the

vehicle, it may be necessary to carry out grinding, bending or rearranging operations

for correct fit. These operations must follow sound, standard shop practices.

6. Left and right definitions in this manual are determined when sitting in the driver’s

seat, facing forward.

7. All fasteners must be of the correct size and torqued according to the specifications

shown below. Torque specifications are in foot pounds (ft-lb).

8. The possibility exists that the primary installer may be color-blind. Always ensure that

another person confirms the color codes on the wires.

If the threads are dry, add 20% to the torque value.

1.3 Installing the compressor

NOTE

Make sure that the surfaces that the main mounting bracket will contact are clean and free

of contaminants or debris. If the mounting bracket does not seat correctly against the

timing cover or engine block, the compressor and crankshaft pulleys will not align correctly.

1. Install the main mounting bracket for the VR70 to the side of the timing cover using the

eight (8) threaded holes shown in Figure 1.3

Figure 1.3

2. Thread the two (2) M10 × 35 mm hex head cap screws into the two holes on the side of the

engine block (Figure 4). Use 8

3″ flat washers behind the cap screws.

3. Thread four (4) M10 × 35 mm hex head cap screws in the four (4) threaded holes

originally used to mount the OEM air conditioning compressor mounting bracket (Figure 3).

Use 8

3″ flat washers behind the cap screws.

4. Thread two (2) M10 × 35 mm hex head cap screws into the two holes on the rear of the

timing cover (Figure 4). Use 8

3″ flat washers behind the cap screws.

5. Torque the cap screws which thread into the cast engine block to 45 ft-lb. Torque the

cap screws which thread into the aluminum timing cover to 35 ft-lb.

Figure 1.4

1.4 Installing and mounting components

1. Clean all dirt and paint ridges from face of OEM pulley. Install the VR70 pulley over the

OEM pulley and harmonic balancer. Align the mounting holes.

2. Apply Loctite and install five (5) M14 1.5 × 80 mm hex head cap screws. Torque

them to 145 ft-lb.

3. Fit the VR70 belt tensioner to the front of the mounting bracket using the M12 × 80 mm

hex head cap screw (Figure 1.4). Apply Loctite and torque it to 80 ft-lb.

NOTE

4. Remove the ½″ × 1¼″ UNC flange lock bolt securing the back idler to the bottom of the

mounting bracket. Apply Loctite and torque to 117 ft-lb. Be careful not to lose the

aluminum spacer that fits over the lock bolt and into the center of the idler.

If the VR70 belt tensioner is already fitted on the mounting bracket, remove it, apply

Loctite to the M12 × 80 mm hex head cap screw and torque it to 80 ft-lb.

mm hex head cap screws, install them and torque them to 25 ft-lb.

11. Install the supplied 6-rib VR70 drive belt over the crankshaft pulley, VR70 compressor

pulley and the VR70 tensioner (Figure 1.7). Check alignment of the pulleys and belt using a

straight edge.

NOTE

Do not tighten these fasteners at this time.

These fasteners are threaded into aluminum. Over-tightening will damage the

aluminum threads.

If the pulleys and belt do not line up correctly, check the installation of the mount-

ing bracket. If the fasteners have not been tightened properly or if the bracket has

not been installed flat against the timing cover, the pulleys will not align correctly.
