Now attach the cooler brackets to the vehicle and then attach the cooler to the brackets. Now center punch and drill your holes in the desired locations. Place the cooler in the area you want it and mark the area where you want the bracket attached. Now pull straight out on the grille at each side around the headlights, be careful this is where I broke my retainers. Now remove the two bolts in the first bay of each side of the grille. Now remove the two bolts at the top of the grille from the front. On the back side of the grille from under the hood remove the bolt on each corner. Once the bolts are loosened lift the brush guard up and set it aside, now go ahead and remove the four bolts all the way and set aside the brackets. Now you have access to the hook bracket and brush guard mount, If you have a brush guard, loosen the bolts only at this point, otherwise go ahead and remove them. So first off remove the skid plates to give yourself access underneath. Per B&M they state “The cooler will guard against excessive overheating, but will not overcool the transmission in winter weather” The reasons I chose this one is that it is a stacked plate design, good BTU disbursement and built in bypass. I bought it from JEGS for 65.99 + Handling. The Kit I bought is B&M 70264 Transmission Soopercooler 24000 GVW and 14400 BTU.
