Les Hurdle Posted April 11, 2023 Share Posted April 11, 2023 This no doubt a dumb question but I live on a dusty road and have never had a 'pusher' before. The rear end of the coach and the radiators get covered in dust.......... I realize I can blow off the dust.. but any 'smart' ways to prevent it entering the cooling area?

DavidL Posted April 11, 2023 Share Posted April 11, 2023 No way to prevent it. Get a power washer. Drive slower Get the road chlorided (to keep the dust down) Monitor your air filter but don't open it up until you wash down the engine compartment to keep dirt from getting into the clean side of the filter which ends up in the motor (a bad day) Link to comment Share on other sites More sharing options...
Solution Rikadoo Posted April 11, 2023 Solution Share Posted April 11, 2023 Aside from move to a different spot, not really, im not sure if the fan that changes pitch with RPM fluctuations would help. Mine gets the same everytime we head out to Nevada to go play, things to watch out for is as the engine runs an creating “blow by” it too is being thrown at the radiator, mixed with the dust it starts to restrict airflow☹️ make sure you keep the radiator clean often, especially look from the inside towards the radiator to make sure it’s not Plugging the fins up with the glop.

Les Hurdle Posted April 11, 2023 Author Share Posted April 11, 2023 Many thanks folks. I do not own the road and the state of the road is a bone of contention which others could care less about. I have blown the sand off the rads but will buy a small electric blower to get to the engine from the inside. L Link to comment Share on other sites More sharing options...
Tom Cherry Posted April 11, 2023 Share Posted April 11, 2023 You probably need to spray the radiator every year of so with a pump sprayer (like you use on weeds). I mix a 4 part water and 1 part Simple Green and add a "dash" of Dawn dishwashing detergent. Rinse the radiator first and get it wet. Then spray it. Both side, if you can. Let it soak for maybe 5 minutes. Then rinse with a garden hose....NOT A PRESSURE WASHER. Run the engine...we do that on the side radiator MH....

Chargerman Posted April 11, 2023 Share Posted April 11, 2023 Just be careful with Simple Green. Not good for an aluminum radiator (if you have one). They make also have a product that is safe on aluminum 1 Link to comment Share on other sites More sharing options...
Gary 05 AMB DST Posted April 11, 2023 Share Posted April 11, 2023 Do not use a power washer. It will bend the fins. I wash the radiator from inside like Tom just described. Spraying the radiator with a water hose, front or back, will not get the water through the fins, too much weave back and forth. The good part is starting the engine after rinsing from the inside, one heck of a soap bubble storm out the back. Gary 05 AMB DST Link to comment Share on other sites More sharing options...
Happycarz Posted April 11, 2023 Share Posted April 11, 2023 Simple Green Purple is the Simple Green you want that is safe for aluminum. 1 Link to comment Share on other sites More sharing options...
Les Hurdle Posted April 11, 2023 Author Share Posted April 11, 2023 Hi all Thanks for the info...... all of the rads are after market. How about air jets? L Link to comment Share on other sites More sharing options...

Simple Green is safe. In addition diluting it makes it “even more”. A myth that has been floating around. Link to comment Share on other sites More sharing options...
Jdw12345 Posted April 12, 2023 Share Posted April 12, 2023 I married into a farming family, myself, I was in the trucking business, one thing I’ll share with you after cleaning radiators and after coolers on trucks and large farm equipment is use, compressed air first before you put the water to it, if you didn’t know! 1 Link to comment Share on other sites More sharing options...

DavidL Posted April 12, 2023 Share Posted April 12, 2023 Any tool requires an understanding of how to use it. When using a power washer, take the material in account on how much pressure, distance, direction and time to clean. Choice of tip and pump pressure is key.

Les Hurdle Posted May 17, 2023 Author Share Posted May 17, 2023 I plan on using air filters velcroed inside the rear doors when I go down our dusty road.......... I do realise some of the dust could be forced into the 'coach side' of the rads. However, the engine/trans/cables/wires gets covered in oil mist seconded by dust. I have tried to blow it off from the bedroom access panels but wonder, what damage can I do to the Engine etc if I use compressed air? L Link to comment Share on other sites More sharing options...
