Installation Notes

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

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).

1.2 Installing the bracket

1. Automatic Transmission

Remove the OEM hose barb fitting from the cylinder head which held the OEM steel

coolant line for the transmission cooler. This may have an internal hex. Apply Loictite PST to

the supplied 1/2 NPT 5/8 inch hose barb and thread it into the supplied brass 45 degree

elbow, then thread the assembly into the OEM hose barb location in the cylinder head.

Angle it downwards about 20 degrees (Figure 1.4).

Manual Transmission

Remove the plug in the side of cylinder head just below the front lifting lug location, then

install the supplied 45 degree brass fitting and hose as for the automatic transmission.

2. Connect the supplied 40 x 5/8 inch heater hose to the 45 degree fitting in the cylinder head,

install the supplied hose clamp and tighten. Route this hose down behind the egine oil filter.

compressor mounting bracket. Thread the four (4) M8 x 20 cap screws and 5/16 inch lock

washers into place and torque to specifications (Figure 1.5).

10. Install the OEM lower rad hose and clamp.

end fitting on the OEM transmission cooler (located on the side of the engine under the

exhaust manifold). Install a hose clamp and tighten. Route the hose foward and down

beside the engine oil filter.

2. On Manual transmission models (Figure 1.8), cut the OEM heater return hose

approximately 1 inch before the bend. Insert the sipplied plastic Tee and secure it with the

supplied hose clamps. Route the hose clear of the exhaust manifold and tie it to the A/C line,

then route it forward and down under the radiator and clear of all hot or moving parts.
