DP started overheating after a repair

Kayteg1, I reread your post can't tell what your are really saying other than rear radiators are "tricky animals". The url you presented doesn't have anything to do with the subject at hand but back to your post, we may be saying the same thing. Normally air is sucked thru the radiator by movement and the fan but on rear radiators, the fan sucks the air from the engine side and blows it thru the radiator backwards. I'm presently looking around the RV park we are presently in to find a similar RV that someone will let me crawl under :)
Thanks for the info.
