Hi,
I would try washing the radiator again, and see if there is any more dirt on it.
Do you have a coolant water filter? Napa sells a kit #fil 4019 to install one on a 5/8" heater hose line. The coolant filter for a normal pickup is 4070, and they do sell higher capacity filters. If you never ran a water filter, I would suggest starting there. Change it after about 800 miles, it will remove a lot of junk from the engine, and any left over sand. When you notice the heater is not heating anymore, it is time to change the filter again, as it will plug a couple more times in the next 8,000 miles. Then should last 1 year between changes. I replace mine every September, so that the heater will work all winter.
I have a gas engine F-53 - 1997 Ford chassis. I have never had any overheating problems, and the water pump should last many more years due to the lack of minerals in the water.
Some members get offended by a question written with all capitol letters. In some blogs it is considered "Rude" or "Shouting" - as in trying to get your point across by typing in all caps. After taking several customer service seminars, I have learned to not worry about trivial things.
My friends with a Phaton had a problem with it overheating. Their solution was a quart of simple green in a chemical sprayer, mix about 10% green and 90% warm water, then spray some on the radiator, then let it soak, and then wash it out, until after soaking and washing did not bring out any more dirt. It took all day!
The outside coil is probably the A/C cooler, then the air charge intercooler, then the radiator nearest the engine. You need to wash all three coils. You might have to crawl under the RV and then spray the radiator from the inside, or perhaps from under the bed, you can get at it?
Charge cooler leaks can also overheat the engine. Why? Hot air from the turbocharger might not be cooled enough, before going into the engine, and that can mean 1,000F air into the engine only designed with 250F air in mind.
PS: Don't try cleaning the radiator in a campground, unless they have a special place to wash RV's. It will make a mess of the parking area, and management will not be happy. A pressure washer at a self serve car wash might work well too. Or a 1,000 PSI pressure washer - Just use great care not to bend the fins on the coolers with the pressure washer, it would be possible to wash a hole right into and through the metal with to high of pressure to close to the metal coils.
Good Luck,
Fred.
