Overheating Diesel Pusher

I have a 2005 Itasca Meridian with a C-7 engine with a rear radiator. On my last trip, I started to see early signs of over-heating. This was the first time I ever had over-heating issues. The CAC was clean as a whistle, radiator full of coolant, and fan/water pump belts were tight. Thermostats had been replaced about a year ago. Slobber tube extended years ago. Made it home OK, but had to take it easy on long hills.

I pulled the radiator and CAC (no small amount of work) and was surprised to see a large pile of leaves, pine needles, candy wrappers, and bird feathers between the CAC and radiator that had blocked probably half the radiator......obviously the cause of my heat problem.

I have included a picture of about 2/3 of the stuff (hammer is for scale).

Lesson to be learned: a clean CAC doesn't mean your radiator is clean.

Overheating Diesel Pusher

Had the same problem-- worse-- two years ago pulling southbound grades on I-84 in Idaho/Utah. Triggered the high-temp alarm a couple of times.

Took it to Freightliner in Salt Lake, and they pulled a huge pile of junk out. Then the pressure steamer pushed so much impacted crud and grit out of the vanes there was a river of brown slurry running across the floor. Rock steady on 195* ever since- winter and summer.

Thank you Sir,

This is just the info we all need to post to help others realize the potential problems that could elude explanation.

These things are not easy to see if you don't know to look in the right places. It can also happen on new coaches, as birds will nest in odd places.
