I wonder if the exhaust pipe running next to the cooler, under the car,
is producing enough heat to reduce that coolers efficiency?
I really think that with the fans and shroud between the hot exhaust plus at speed there is going to
be alot of air flow and not much heat transfer. When the fans ARE on, they are pulling air thru the
cooler, so air is coming from the frame side of the cooler. But I have still ordered the insulation you
pointed out, it can only help, plus I found another place where it's going to be needed.
I jacked up the Navigator again to verify that I have the return line going back to the trans. The return
line obviously has to be the line that comes out of the radiator and goes to the OEM cooler, so I
followed this line thru my setup in the front until it went below the engine. I then marked it with some
blue masking tape so I could see it on the other side of the cross-member.
From there I could follow the line and see that it went back to my remote filter, then into the
2nd Derale cooler.
I'm sure glad to put that possibility to a rest, I would have been really disappointed if I had
everything plumbed in the wrong line.
The other place where I might have a heat related problem would be shown below where both
lines run very close to the catalytic converter. The line with the tie wrap was closer until I moved
it before I took the photo below.
Can I wrap the converter, or can it get too hot ?
I wouldn't need to wrap the whole converter just the first 4-5 inches.
