KCRAY, I have been following your thread since the beginning. A good one, with a sensible solution to a problem. I haven't been in any extreme heat just yet, mid 80's only. Even at that the AC is a little weak, especially compared to my other cars and trucks present and past. I have a valve on the way and will cut it into the heater core line as you have. Us old time truck driver's used to shut off the heater cores all the time before AC was required in the cabs.
What I noticed today when I was under the hood struck me as odd. The AC compressor is on the left side of the truck instead of the right side. The suction line, and return is routed all the way across the front of the motor and down the right side above the wheel well and then into the firewall. In addition most of the length of suction line is uninsulated except where it goes around the front corner and then in thru the firewall. Seems to me, we are losing a lot of the cold from the freon, on the way to the AC core in the cab. If you look at the photo you will see the condensation on the top line, which is the suction line.
What I'm wondering is what material can we use to wrap this line to shield it from the engine heat, that will take the heat and environment of the engine bay when it gets extreme. Is there a reason NOT to wrap it.
If one of the Ram Cares reps sees this. Please forward it on to the powers that be. I would like to understand why it was designed like it is. What's the reasoning?
