Some of you know I have had some cooling/ overheating issues with my '86 F 250, especially when towing the 5th wheel.
As I prepare for the coming IDI weekend---thats one big, long grade on I68, I want to make some changes. Here are my thoughts so far.
Several years ago, I added A/C to my truck. The A/C interfered with the transmission cooler built into the radiator, so I bypassed it. I already had added one extra cooler, so when I bypassed the radiator tranny cooler, I added a second aux cooler. So I had 2 coolers, and the A/C condenser in front of the radiator.
Maybe I have too much obstructing the air flow. I am also putting all that extra heat into the air before it ever gets to the radiator. No wonder I have cooling problems.
Solutions---
I want to relocate the 2 aux transmission coolers. Do any of you know what kind of air flow we have under our trucks? I am thinking of relocating the coolers under the cab, outboard of the frame rails on the driver's side. It certainly LOOKS like there would be plenty of air, but does anyone know for sure?
2nd solution---Like many of you, I use the heater to dump excess heat ( into the cab), but its better than over heating. What do you think about pulling the square plug from the driver's side heat and allowed hot water to flow from that head, thru and extra heater core installed somewhere below the truck? The water would return thru a tee in the heater line that dumps to the water pump? Is there a danger of over-cooling? Could over-cooling adversely affect combustion?
Thoughts?
Ideas?
Help?
