Side radiator cleaning

I've always admired side radiator motorhomes, especially since they are usually associated with higher-end coaches. After cleaning mine today, I am even more impressed.

Having had a rear radiator pusher for the past 8 years, I had come to appreciate if you don't clean them at least annually, they will likely run hot when you ask the engine to work hard. It was always a messy ordeal.

Today I did the Allure. Sprayed the outside and inside (what I could get to inside) with my usual mix. Let it sit for about 10 minutes, start the engine and then flush with clean water from the outside. Basically, there seemed to be no dirt or grime in what came out. When done, I did notice the fan blades are now very white.

  • I've yet to clean my side radiator and my CAT runs <195F under any road conditions.
  • Being away from the slobber tube vapors, and up the side of the coach away from the rear wheel dust, really helps the rad stay clean.
