When I purchased mine the owner told me about this issue, not a problem with fan just what happens when your drive on unpaved roads. He was anal, so we got down and he had cardboard made that would fit under the radiator/fan and bungee cords, he showed me how to hook it up, but he cautioned not to leave it on, but it stopped the dust. He was a perfectionist, I kept it for 4 years and just threw it away, I don't get on many unpaved roads.

I have a 2001 ISC 350hp with 74,000 miles. Just had it serviced at Western Bus and they said valves etc were fine. I have seen lots of 5.9 24 valve trucks with 300 thousand and running fine. The 8.3 is a million mile engine, just keep regular maintenance preformed. I am a Cummins guy don't care for Cat.
