Mine was routed originally to a fanless cooler mounted at the radiator. I disconnected the return line and downstream from the fanless cooler and installed a derale hyper cool 25 stack plate with an 8" fan under the drivers side floor. Wasnt too bad to route the line. Just routed the return to the derale then installed a new line to the trans. Added the temp sensor to the derale output line. I didnt want to run a whole new line from the fanless to the derale so just extended the original line by another 24" to get to the derale.
BTW tried the 10" derale and due to the position of the inputs, it was super tight to fit under the drivers side. Returned and installed the 8" and it was much better. I tested it running up the grapevine ~6% grade at 98 degree ambient pulling a ~5K trailer and the temp did climb to about 230 but dropped fast when I pulled over. Not towing it never goes over 190 even on the hottest days in S. California.
I believe Mark installed his in the front skid plate. Might be a better location given its better protected but for me its so tucked up there above the frame.
