I tend to over thing and over-engineer my stuff, but nothing sucks worst than being on the side of the road in the middle of nowhere. So, I tend to err to the side of caution. I want to try and eliminate as much of the unnecessary heat that builds up while towing.
I started on the last entry with the deep pan. That adds about 3 qts of fluid, which will give more capacity to carry the heat away from the transmission.
I looked for a place to mount this cooler up front. The problem is a real estate issue. There is only so much room available, so I had to pick what I wanted up front. I'm not a fan of installing anything in front of the radiator, but with the new R134 systems, keeping airflow moving is key, so the A/C condenser won out. I wanted airflow while I was moving, so I started looking…I wanted it away from the floor boards, so the heat wouldn't transfer to the passengers feet. I finally settled on an area below the cargo bay floor. It's not ideal, but if we are pulling our little trailer through the mountains, air will be moving across it.
