I finally had the radiator removed and was shocked to see how badly it was clogged from the backside. I assume it happened because it was 9 years old when I got it and the people before us had never extended the slobber tube. The stuff clogging the radiator was so hard I could have never gotten it off with any washing I could do.

We replaced the radiator and had the CAC cleaned. While they were in there, we had belts and hoses replaced, and replaced the water pump.

My guess is you have a clogged radiator.
Well Sir,
You've found out what I've been advocating on here for years. Attempting to clean a radiator and CAC in a rear radiator coach, with all the tight clearances and for the most part, IMPOSSIBLE access, is quite often, almost useless. It's the nature of the beast here. I'm fairly sure they, (the designers of the first rear radiator coaches) didn't actually intentionally design them so that the radiators HAD to be removed in order to clean them accurate and efficiently.

But, it's the name of the game here. Oh, one can limp their coach along but, without a doubt, removal of the radiator and CAC is the most accurate way of cleaning them. I've had mine out twice in the time we've owned it and, the first time was at 40K miles and about 6 years old. It was SERIOUSLY CLOGGED at that time.

The second time, about 8 or so months ago, I pulled it again to do other engine maintenance and, was amazed at how bad it was, even though the slobber tube had been extended to the rear of the coach, and exited right next to the exhaust tip. Those fins are just a natural for accumulation of anything and everything that's on our roads. Well, you should be good to go now. Good luck and happy RVing.
