I put mine in back over winter. It seems to do fine as long as I remember to turn the fan on. The temp. runs around 180-185 with the fan, but got up around 220 without. I mounted it on the framerail in front of the rearend on the driver side. I also made a block to connect the braided line to and ran steel line to the cooler. If the trans. needs to come out, the lines can be disconnected from the block.
