Absolutely. No way would I ever run mine with a 160 degree thermostat. It will be more efficient when it's running on the warmer side - as long as it doesn't get TOO hot.

It sounds like you've gone through the entire cooling system. It certainly should be up to the task. Does it actually overflow coolant? Or does the gauge juts read too hot? Have you verified that the temperature reading is accurate? A faulty sensor or gauge could have you chasing your tail on this f...

Inspection hole with the cover in place:

Duh... That was Dwayne who posted the photos

So I cut a 3-1/2" inspection hole in the bottom of the shroud as far rearward as possible. Above my new hole there is about a 1" gap between the radiator frame and the CAC with about a 2" gap between the cores. Looking up there with a light it's pretty clean. There are just a few blad...

Jeff, Not sure I understand the problem. Have you raised the bed and looked inside the fan shroud? That should give you access to the front of the CAC, and as you say a few rows of the radiator core. That (the front) is where the vast majority of the dirt and debris will be deposited. Yes, you can ...

Mel, it looks like you put an image in your last post but it isn't visible to be.
All I see is this:

I can't see an opportunity to get access from the top. It would have to be under the surge tank. At least on my coach the Intercooler is a couple of inches shorter vertically than the radiator. When I look in from the front I can see the bottom few rows of the radiator showing below the bottom of th...

...So if you can loosen the shroud safely and peek inbetween you may find what looks like a birds nest. Hard to tell from the photos but it looks like maybe the 'bird nest' is about 1-1/2" thick. Is that about right? If there's that much space in there I think it will be very worthwhile to mak...

Jeff That is a good question. I don't have the answer because on my my coach the intercooler/radiator "sandwich", (as assembled by SMC/Magnum), has always & only been cleaned in place. I'm considering cutting a 4" x 10" access hole (with a replaceable panel) in the bottom of...
