Had my Itasca Horizon 40KD overheat traveling from Phoenix to Flagstaff on I-17 as the route has several long upgrades. I brought the MH to Cummins for service figuring they could diagnose and fix the problem. They diagnosed the problem to be a plugged radiator, but they said they didn't work on radiators including flushing them, they only work on the engines. This a Cummins in Las Vegas. Here I thought the cooling system was part of the engine, I guess that what I get for thinking! I have now taken the MH to Frightliner and they are going to fix the problem. I now will not take my MH ever to Cummins only to Freightliner, who I have always had good service with. Yes, Cummins charged me over 3 bills for that info. Lesson learned!

That is interesting. It is true that while your engine is Cummins, Freightliner built the chassis. In your case, your best bet is to find Freightliner Oasis service centers. I now have my first coach with a Cummins engine and I plan to use the local Cummins Coach Care Center for my service whenever I can. I would expect a Cummins Coach Care center to deal with most anything related to the chassis. They would pull the radiator and send it to a radiator shop for cleaning.

Our experience last summer with two Cummins Coach Care Centers and another shop that works on Cummins was less than stellar. I am very disillusioned with Cummins shops. What was a plugged second in-line filter that Cummins should've known about and didn't resulted in thousands of dollars of diagnostic time and hours and hours of us being held up while they tried to find the problem but didn't. I found out what to look for on this forum, which turned into a $15.00 part that we bought and DH installed. Even after I tried to tell the Coach Care center about it, they claim we didn't have a second filter. Of course, the first fuel filter had been changed several times throughout our trip as that seems to be the first thing they do. After I called Freightliner and was told where the in-line filter was located and that Cummins should've known about it as they are the ones who made Freightliner install it, were we able to take it into our own hands. I have no faith in a Cummins shop.

Wow... I can't believe they didn't help you better. Big deal, radiators are simple.

There isn't a Coach Care facility in Las Vegas (there is on in Sparks, just off of I-80), only a Cummins service facility that does mostly trucks and might work on the engines of MHs but usually do nothing else.The radiator isn't part of the engine, it is designed by the chassis manufacturer. Most Coach Care facilities will do flushing, etc., but not all. It is a question of it being harder to work on coaches than the big trucks that is their main business, so they often just don't want to get involved in doing that. Sort of depends upon how busy they are, how experienced their help is, etc.Barb

There is a fuzzy gray line between what is the engine manufacturer's problem and what is the chassis manufacturer's problem. Different shops have different opinions.

We found that a Cummins 'truck' facility is much different than going to a Cummins Coach Care facility. We were told at a 'truck' facility that our 40' motorhome was too small to work on! We could easily understand at the time in that they had many trucks waiting to be serviced and getting on the road. Since then we have always gone to Cummins Coach Care, Coburg, Oregon (no sales tax).

OP was at Rocky Mountain Cummins facility in Las Vegas. It is a Cummins truck facility. Rocky Mountain Cummins has 10 coach care locations in Phoenix, AZ, Denver, CO, Grand Junction, CO, Boise, ID, Billings, MT, Albuquerque, NM, Reno, NV, Elko, NV, El Paso, TX and Salt Lake City, UT. The Cummins Coach Care locations are more use to working on diesel pushers in motorhomes and coaches.

Don't judge every facility guilty just because You happened to be let down by one!

That said if You do have a legitimate complaint You should be taking every step possible to bring that to the attention of the Senior Management of the Establishment in question!

If it is a Genuine Cummins Shop there must be a Manager of Corporate relations that You can contact with the documented details of Your Complaint!

I have always found that regardless of the situation most companies have someone with whom to discuss the problem and are willing to resolve any issues to the satisfaction of all concerned.

The Cummins repair shop in Las Vegas steam cleaned the radiator in my Monaco in April. They must have changed their policy since then?

I would have taken it to Northern Arizona Diesel in Flagstaff. Excellent service, good rates. Great bunch of techs.

Cummins in Tulsa flushed our radiator and refilled the ES Compleat Coolant. Guess it depends on the shop. We have a Cummins on a Country Coach chassis.
