Installation Guide:

The installation of the Munji Transmission Cooler Kit requires basic mechanical and tool knowledge. It is important to follow these instructions:

N.B: NEVER REST ANY PART OF YOUR BODY UNDER A VEHICLE OR HEAVY COMPONENTS UNLESS YOU HAVE SUFFICENT SUPPORTS AS WELL AS THE JACK. A HEAVY WEIGHT CAN SLIP OFF A JACK OR THE SUPPORTS. PLEASE ALWAYS BE CAREFUL AND KEEP YOUR PHONE WITHIN REACH IN THE CASE OF THE UNEXPECTED.

1. Ensure the vehicle is on level ground, and you have around 3 litres of Compatible transmission fluid to top up the gearbox. Begin by removing the top grille cover under the bonnet, grille and front bumper bar. For BT-50s, you need to unclip and slide the top painted panel of the bumper forward and off to get to all the clips for the top cover.
   

2. Remove the Upper bumper support and centre brace for the bonnet lock and set aside. Also unclip and remove the lower half of the radiator shrouding.

3. Unplug the 2x Horns and unbolt from their mounting bracket.
4. Fit the 2 rivnuts with a rivnut crimper in these spots.

5. You can now prepare the transmission cooler to be mounted. It should already be bolted to the mounting bracket, however we always recommend rechecking the mounting bolts are tight.  Fit the 2x Inverted Seat adaptors to the outlets on the cooler and tighten. Be sure to hold the outlet of the cooler with a spanner when tightening to prevent it cracking off. Then fit a 90 Degree barbed AN fitting to each side of the cooler, and tighten pointing to the LEFT when facing the BACK SIDE of the cooler (Side WITHOUT Munji Logo). 
   1. Fit Inverse Flare to AN Adaptor
   2. Tighten while supporting Outlet Nut
   3. Fit Angled Barb AN fitting and tighten facing the LEFT when looking at backside of Cooler
6. Now you can fit the bracket to the vehicle. Start with loosely bolting in the centre mount which bolts into the bottom of the bonnet lock. Reuse the factory bolt. This will hold the cooler up while you fit the remainder of the bolts. Refit the horns, sitting them over the cooler bracket and slipping the locking tabs into the factory holes. Reuse the factory bolts. For the lower middle 2 bolts, reuse the factory bolts. The outer 2 bolts use the supplied M6 bolts and washers but DO NOT FIT them yet! They will be fitted after the radiator shrouding is refitted. Keep everything loosely bolted till all bolts are fitted.

7. You can now fit the hose to the cooler. Cut the supplied hose with one half being roughly 600mm longer. The longer hose will go on the driver side of the cooler, and can be ziptied to the centre bracket using the 2 slots. Fitting a hose clamp to each hose and tighten. Refer to photo above.
8. Now run the hose around the front of the Left Hand Side of the vehicle and down under the radiator support. You will need to cut around the intercooler shrouding on the left side to run the hose through the shrouding and down. The lower radiator shrouding can be refitted and trimmed around the transmission cooler where necessary. Instead of clips, it will bolt in at the bottom. Fit the supplied M6 Bolts and washers to the lower radiator shroud and lower transcooler mounts and tighten. Tighten all the other bolts that were previously fitted too.

9. Run the hoses between the LHS Strut tower and engine, zipting as you go. Ensure they will not rub on anything to prevent wearing through. Run them back to the factory transmission cooler. Remove the fluid line circled below, and connect one hose to the upper steel line, and the second hose to the centre outlet on the factory transmission cooler. You will need to gently loop the lines to prevent them from kinking as you bend them 180 degrees to meet up with the outlets. Check the length needed and cut down supplied hose till it fits nicely in the space between gearbox and chassis. Fit hose clamps and tighten them.

10. Once you have fitted everything, check everything is tight. You can now start the car and check the gearbox fluid level. Let the car idle for a minute, then remove the check screw (Allen Key bolt with Check engraved on it - DO NOT REMOVE 14MM AT REAR OF PAN AS THIS IS THE DRAIN PLUG). The car must remain running and in Park during this time. If no fluid drips out, remove the 24mm fill plug on the drivers side of the transmission and fill with compatible ATF until it starts leaking from check point. Refit 24mm fill plug, and when oil slows to a dribble out of check point refit the Allen key check plug.

11. Check there a no leaks from all hose connections, refit bumper bar and grille and you are done! 

It is always important to go for a short test drive and re-check all nuts/hose clamps are tight.
