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 underhood 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.

1.3 Installing the cooler

1. On 4x4 trucks, remove the two (2) 12 mm OEM cap screws from under the front of each

chassis rail which hold the tow hooks (Figure 1.9). On 2x4 trucks, use the holes in the

same locations on the chassis rail as in the 4x4.

Figure 1.9

2. Fit each of the two (2) cooler mount outer brackets (Figure 1.10) with the central drilled

holes upwards and inboard of the chassis rails, align the holes and install the OEM bolts (on

4x4 trucks) or the supplied 12 x 30 mm hex head cap screws (on 2x4 trucks). Then install

the center section of the cooler mounting bracket and tighten all the fasteners.

Remove These Cap Screws

DOCUMENT 19340

3. Install the cooler with the hose spigots for the coolant hoses facing the passenger side of the

truck. Apply Loctite and install the two (2) 3/8“ x 3/4“ flange lock bolts, then torque them to

specifications. Figure 1.11 shows the cooler in position.

4. Use the supplied hose clamps and hoses to connect between the cooler and lower radiator

hose connection and the cooler and the water pump. On the 5.3L engine, use the shorter

length of hose to connect to the radiator (Figure 1.12). On the 6.0L engine, use the longer

radiator hose with the 45 degree elbow (Figure 1.13).

Figure 1.11

Figure 1.10

DOCUMENT 19340

5. Align the hoses so that they are not kinked or stressed and tighten the hose clamps. Make

sure that the cooler bracket and hoses clear all transmission cooling lines and the steering

linkages.

Figure 1.12 5.3 radiator hose

Figure 1.13 6.0 radiator hose

1.4 Completing the installation

1. Install the lower radiator fan shroud.

2. Install the fan and the supplied fan spacer and tighten the fasteners.

3. Install the upper radiator fan shroud.

4. Check all hoses, lines, wire harnesses and cables to make sure that they clear all the belts,

pulleys or other objects that could cause damage.

5. Install the upper radiator hose and fill the cooling system with the OEM recommended

coolant mixture to the correct level.

NOTE

When operating the engine for the first time following installation, be sure to allow the

engine to reach full operating temperature and ensure that the cooling system level is

correct. Failure to do so could result in an overheat condition and possible engine

damage.

6. Install the air filter tube, filter and resonator box.

7. Attach the bracket with the red battery cable splitter box to the VR7000 bracket using the

OEM fasteners (Figure 1.14). Connect the fusible link wire and fit the plastic protective

loom around the wire.

Part 2: Installing the Air Tank and Lines

2.1 Installing the tank mounts and the tank

The tank mounts supplied with this system are designed so that they can be mounted on the frame

without drilling holes. The tank is secured to the frame using two L-brackets that hook over the

chassis rail and are secured with wire cables and backing straps. The tank and clamps then locate

on the L-brackets

1. In preparation for mounting, thoroughly clean the frame under the cab on the passenger side

of the vehicle.

The upper line connections on the tank will not be easily accesible after the tank has

been installed on the frame. It is recommended that you attach these two lines before

installing the tank on the frame.

2. Connect the 5/16“ x 1161/2“ scavenge line (part #17343) to the tank at location 3 and tighten

the fitting (Figure 2.1).

3. Connect the 1/4“ x 1191/2“ pressure control line (part #17344) to the tank at location 2 and

tighten the fitting (Figure 2.1).

4. Most applications come with the tank band clamps fitted to the tank. It is easier to fit the L

brackets loosely to the tank band clamps and install tank and L brackets together. Fit the L

brackets to band clamps as shown in Figure 2.2. Hook the two chassis L- brackets over

the frame between the two body mount brackets on the passenger side of the truck. Place

the threaded end of the wire cable through one of the slotted holes in the backing strap and

feed the cable over the frame rail with the backing strap on the inside of the frame.

5. Wrap the cable around the L-bracket and frame, then feed the threaded end of the cable

loosely through the lower slotted hole in the backing strap. install the washer and nut.

Repeat this procedure with the second bracket. Leave loose until tank alignment is

completed.

6. Locate the tank and the brackets with the air outlet to the rear, the sight glass and line

connections to the front and in the correct alignment as shown in Figure 2.1.

7. Install the front end of the tank 5” back from the rear most part (support plate) of front cab

mount.Adjust the position of the tank so that it clears the cab mounts and so that there is

sufficient room to attach the hoses. Make sure that the tank alignment is correct (Figure

2.1), then tighten the wire mount cables, making sure that the cables rest against the guide

bar. Bend the exhaust heat shield clear of the cable ends to prevent vibration noise.

Figure 2.3 shows the front tank bracket in place and Figure 2.4 shows the rear tank bracket

in place. Figure 2.5 shows another view of the tank and brackets.
