Made the trip to Quartzsite,AZ this year. Caterpiller engine still running, heard a lot of noise from engine area. Turned the engine off and discovered the fan bearing was blown. I had the parts on hand. Took me 2 days to replace the fan bearing,bearing housing,serpintine belt & V-belt. Most of the work done from bedroom closet area. I have a rear radiator. I only have 28,000 miles on the coach. I learned from another forum that the cat C-7 engine was prone for fan bearing problems at around 27 to 39,000 miles. That's why I ordered the parts and had them on hand. Talk about being "LUCKY". All the work I performed myself. I had scratch marks,bruises,cuts. Looked like someone beat me up with an ugly stick and then ran over me a couple of times.
