Product Usage Instructions
-
Start by assembling the top bracket and the bottom bracket to the coolers using 6x M6x16 bolts and M6 nyloc nuts. Do not use washers for this step.
-
Position the coolers as shown in the photos and ensure the bottom bracket overhangs the cooler according to the red lines in the photos. This is the correct orientation of the bottom bracket. Use nylon washers between oil coolers and stainless brackets.
-
Install the L-shaped brackets onto the bottom bracket using the remaining available holes with the remaining M6x16 bolts and M6 nyloc nuts. Do not use washers for this step.
-
Ensure the longer part of the L bracket is attached to the bottom bracket and that the L bracket is mounted touching the bottom bracket and not the cooler.
-
Use hose clamps to connect the coolers with a 430mm length of transmission cooler hose. Follow the outlets as pictured. Make sure to orientate the hose clamps exactly as shown in the photos. Cover the connected hoses with split tubing to protect the rubber.
-
Attach the remaining length of hose to the remaining cooler outlets using hose clamps. Again, orientate the hose clamps as shown in the photos. Hold the hoses against each other and cut at the middle point to create two even amounts of hose. Cover the cut
ends with the remaining split tubing. -
Before installation on the vehicle, install 2x M5x25 bolts into the 2x 5mm holes with nyloc nuts. Everest models require double nyloc nuts installed, one on top of the other. Place M5 washers over the nut and a small o-ring to keep the washer in place during
installation. Refer to photos for the direction of the bolt/washer/nut installation into the top bracket. -
Secure the cooler kit assembly to the radiator panel using an M5 washer and M5 nyloc nut as shown in the photos.
-
Fix the provided aluminium spacers between the L-shaped brackets and the radiator support panel using M6x40mm bolts, M6 washers, and M6 nyloc nuts. Ensure hoses are inside the L-shaped brackets before bolting them up. Use nylon washers between L-shaped brackets and aluminium spacers.
-
To remove the OEM cooler from the transmission, clamp the coolant hoses going to the OEM cooler (ensure cooling system is cold and not under pressure). Cut the hoses in the marked positions and install the brass joiner. Use hose clamps to secure. Cable tie
the hoses lightly to ensure they are secure and don’t rub on anything. -
To remove the OEM cooler, remove the 4 bolts that hold it to the transmission as pictured.
INSTALLATION
- Start by assembling the top bracket and the bottom bracket to the coolers as per the photos below, using 6x m6x16 bolts and m6 nyloc nuts only (no washers). Ensure the coolers are positioned just like the pictures, and ensure the bottom bracket overhangs the cooler like the red lines indicate on the photos, this is the correct orientation of the bottom bracket. Ensure nylon washers are used between oil coolers and stainless brackets.
- Install the L shaped brackets onto the bottom bracket using the remaining available holes with the remaining m6x16 bolts and m6 nyloc nuts only (no washers). Ensure the longer part of the L bracket is attached to the bottom bracket, and ensure the L bracket is mounted touching the bottom bracket and not the cooler, as pictured. Ensure nylon washers are used between oil coolers and stainless brackets.
- Next, cut exactly 430mm of transmission cooler hose off the 5mtr length, and connect the coolers using the following outlets as pictured. Use hose clamps and secure (ensure to orientate the hose clamps exactly as pictured to ensure the cooler kit fits in the vehicle correctly) Then cover with the correct amount of split tubing to protect the rubber.
- With the remaining length of hose, attach either end of it to the remaining cooler outlets and secure with hose clamps (ensure to orientate the hose clamps exactly as pictured to ensure the cooler kit fits in the vehicle correctly). Then, holding the hoses against each other and moving towards the direction as pictured, find the middle point of the hose and cut it to separate, this then creates two even amounts of hose to run through the vehicle. Cover with the remaining split tubing when done.
- Lastly before installation to the vehicle, install the 2x M5x25 bolts into the 2x 5mm holes with nyloc nuts (Everest models need to have double nyloc nuts installed, one on top of the other to be used as an extra “spacer”). Then put m5 washers over the nut, and the small o-ring to keep the washer in place during installation (the o-ring will stay there so don’t worry about trying to remove it later). Refer to photos for the direction of the bolt/washer/nut installation into the top bracket.
- Now the cooler kit is ready to install into the vehicle as an assembly. The assembly gets installed into the vehicle from underneath, between the radiator support panel and the air con condenser. The M5x25 bolts installed in the previous step, are to face towards the rear of the vehicle, and will be installed into the following holes. Helps to have a mate above to line the M5 bolts into the holes while the cooler kit gets pushed up into the gap between the air con condenser and the radiator panel, but not essential.
-
Use an M5 washer and M5 nyloc nut to secure the cooler kit assembly to the radiator panel as pictured.
-
Now from underneath the vehicle, it’s time to fix the L shaped brackets. Using the end of one of the hoses as a temporary packer between the a/c condenser and the L shaped brackets as pictured
(you’ll see it perfectly lines up with the 6.5mm hole in the L shaped bracket with the center of the area on the radiator panel that’s getting drilled). Using a 6.5mm drill bit, drill the radiator panel through the L shaped brackets. When the drilling is finished, ensure you debur the holes and apply some paint to stop any rust forming in the future. -
Finally, use the provided aluminium spacers between the L shaped brackets and the radiator support panel. Fix with the M6x40mm bolts, M6 washers and M6 nyloc nuts as pictured. Ensure hoses are inside the L shaped brackets before bolting them up also as pictured. Ensure nylon washers are used between L shaped brackets and aluminium spacers.
- Now that the cooler kit assembly is mounted to the vehicle, the OEM cooler needs to be removed from the transmission. Start by clamping the coolant hoses going to the OEM cooler (ENSURE COOLING SYSTEM IS COLD AND NOT UNDER PRESSURE). The hoses need to be cut in the positions marked below. Install the brass joiner and use hose clamps to secure. Once complete, cable tie the hose lightly so the coolant hoses are secure and don’t rub on anything which will cause a failure in the future.
- To remove the OEM cooler once the coolant hoses have been removed, there are 4 bolts that hold the OEM cooler to the transmission and need to be removed, as pictured.
-
Once the OEM cooler is removed from the transmission, the keeper plate needs to be removed. This can be done by removing the 2 split pins, although sometimes the split pins might be rusty and prove to be very difficult to remove. If needed, being precise with a grinder will remove the split pin and the keeper plate can be removed.
-
Install the provided transmission cooler fittings into the transmission as pictured. Then the original keeper plate can be installed over the top, secured with one of the original bolts and the 2 provided split pins, as pictured.
- It is now time to start routing the hoses through the vehicle. Start by routing the hoses towards the passenger side of the vehicle running between the radiator and the body mount and then along the chassis rail towards the transmission. There really is no right or wrong way here, as long as the hoses are secured, have slack, are not pulled tight and are not rubbing on any other hoses or cables.
-
Once the hoses are routed through the vehicle and are at the transmission, connect them to the transmission cooler fittings. Lastly, secure hoses to each other, close to the hose clamps as this will stop the fittings wanting to turn, as pictured.
-
Before driving the vehicle you will need to top up the transmission with approx. 1 to 1.5 litres of transmission oil. For 6r80 equipped vehicles, using the manufactures specified oil or an approved aftermarket oil, top up the transmission cold until the transmission oil is just slightly above the A section of cross hatching on the transmission dipstick while the engine is running. Move the vehicle through the gears (P N R D) and pause after each change for a few seconds. Recheck oil and top up as required. 10R80 equipped vehicles are much more specific on the oil level and oil used. Please email us for the procedure and which oil to use if necessary.
-
This now completes the install of the HOA transmission oil cooler kit.
