David,

Thanks again for the post, I will double check the bolts as well.
Hope to get this problem resolved on my next visit to a service center. I also have black smoke upon acceleration and have that in several Cummins service centers, now Kevin tells me, after my warranty on the coach is up, that the vendor who provided the charge air cooler admits that they are having problems with those. He suspects that the charge air cooler might be the problem. I've been talking with cc personnel about this problem from the very beginning of my ownership of the coach including talking with Doug Rutherford and now after their obligation is over they think it is something which should have been covered during the warranty period but they failed to mention that as a problem back then. They kept saying it is a Cummins issue but now it is a different vendor issue. As you might understand I am more than a little frustrated with what CC has done for me on this issue since now they tell me that if it is the charge air cooler that they will work to get the vendor to provide a new charge air cooler at no charge but all the labor will be at my expense. I can understand this position if this was a new problem that cropped up after 3 years of ownership but this is a problem which I have had from day one and is documented with both the dealer and with CC calls and emails as well as at numerous Cummins facilities. I don't consider this a closed matter at this point because I am still working to get CC to fess up that this problem should have been resolved during the first few weeks that I owned the coach and thus is covered under warranty as it was a definite flaw in manufacturing process or in defective materials. At any rate I am hoping that eventually I will find a tech who can fix this problem as well as the fan problem.

Is the check for a bad sensor performed by starting the engine when it is cold and check if the fan is running hard??? If this is correct, I think maybe mine is bad.

About the dust storm, when you pull into a campground after running hard on the interstate you are bound to get a dust storm. I think the baffle would help this situation even if you had a good sensor. jerry in NM, '00 Magna.

My baffle was installed by Colton Truck last March after:

Told to turn of the A/C when arriving in a dirt area. No effect.

CC changed an orfice at the Tucson ralley. No effect.
Beaudry/Tucson changed more parts. No effect and money returned. On the third day they had the unit, they recommended that I needed to replace the fan motor. I drove on.
At the recommendation of CC, I visited Colton Truck. They worked with CC and determined that the fan motor and everything else was up to spec. CT recommended fabricating a baffle made out of a new truck mud flap. CC said that they had heard of people of doing this but the CC engineers were afraid of cavitation in the engine compartment. CT said that the way they were going to install the baffle, hanging it below the engine, would not create cavitation. I gave CT the go ahead. It works great.

Butch, if I knew how to do that, I would. I'm old tech. Let me try to explain.
They took a new mud flap made for a truck and hooked it with (4) 1/4"sheet metal bolts and washers to the bottom of the radiator housing. They ran the flap towards the center of the engine. It hangs about 1 1/2" to 2" below the engine and ends just past the center of the engine. As I'm trying to recall, they secured/tied it off with hose clamps in a couple of spots plus a small L bracked they fabricated for one spot.
I'll check the unit the next time I'm at the coach. If the installation is much different, I pass on a note.

re: Dust Storm

Is the problem that you are describing something that is a problem with 2002 Allures? We recently purchased one and have not had it out yet so I would like to know if I should be aware of this problem.

As I understand it, the problem is caused by the fan protruding past the fan shroud a few inches and this somehow allows the fan to stir up dust. I've owned a '98 Allure, a '99 Intrigue and now a '00 Magna and the fan sticks out on all on them. If the bottom of the fan shroud is extended to the edge or slightly past the fan, does fix the problem?? If this is the fix it should be fairly easy to do. Please let us know if this is correct. jerry in NM

The dust storm problem can be summed up in a couple of paragraphs:
It occurs when the engine fan runs all the time on high speed irrespective of the engine temperature. High-speed fans kick up a lot of dust, particularly in gravel and unpaved campgrounds.

The fix(s) are #1. To be sure the programming is correct on the fan controller. There is a complete service bulletin posted in the photo section of theYahoo site.

CCI sells a baffle that covers the lower section of the fan shroud. It seems that the fan blades are wider than the baffle and allow the fan to blow up dust. The baffle is designed to stop this from happening.
I had the tech's look at my 99 Intrigue at the pre-rally in Tucson. They did not have the baffle in stock, but it was ordered and arrived a few weeks ago. I will install it in a few days when I get the ole "round tuit".
On my 99, the thermostat is a non-programmable version and I bought a new one that arrived with the baffle.

I hope this helps. I have had dust storms for several years and I'm looking forward to this as a fix.
