Cooling Fan - Dust Control

Yahoo Message Number: 3566
In talking with some friends, I was told that someone had made modifications to their Country Coach to deflect the air from the radiator fan. This was done so that there would never be any dust blowing up from under their engine regardless of their A/C settings or engine temp.
What they did was to put a metal sheet under the engine and then cut a large hole in the rear engine door and cover it with a stainless steel or aluminum grill.
Does anyone know this person or about the specifics of their work -- how it now functions -- what it looks like, etc.? Would like to see some photos.
Thanks,
Den

Cooling Fan - Dust Control
To answer your question, I have a 2001 Affinity.
I'm a bit doubtful about the fan controls and their ability to minimize the dust after a long day's drive --hot engine and then pulling into a campground with dusty roads. Regardless, I will have CC check my fan controls at the Jan. Rally. Hopefully they will find and fix a problem.
If those controls are operating correctly, does the engine kick up NO dust when you are driving at slow speeds with the A/C turned off? I had the same problem with my 99 Intrigue and they checked the fan controls and told me they were operating properly. So I just assumed that it was a mechanical design flaw for all CCs. I'd appreciate some feedback as to what is the level of dust created when those fan controls are operating within spec.

Thanks and I hope every one has safe and happy holidays!!!

I had the controllers and some burned out wiring repaced on my Intrigue a year ago and it is now acceptable. If the generator or the air is on, I get big dust still. I think you are right that the cooling system is designed to blow out the bottom (where else without opening up the back?).

If you are getting th old CC two-step, I'd suggest you go to Carrier, out by the airport. MUCH more capable than the elves at JC. They fixed a bunch of stuff for me (for less than $1,000) that I had been messing with for two seasons and did some service work (batteries, etc.) that is first class. They are really knowlegeable and more than willing to dedicate resources (by the hour) to solve difficult problems. I think my days with CC service ar ejust about over, as thw warranty is over. It is comical to me that I still have to go to JC (Carrier) to get work done---oh well!
Country Coach has told me that the fans will remain on high when the engine is hot (a good thing), and that they strongly recommend against using baffels to block the air flow. Heat is the biggest enemy of engine life and I intend to extend my Cummins warranty (Cummins has a program) when it runs out. I am very reluctant to risk burning up an engine to mitigate dust, but each one of us has to make that decision.

This may be an inappropriate remark, but we make it a practice to avoid dusty parks when possible. We usually can. If we stick to Trialer Life rated parks of 7 and above, we are usually safe.
