Hello everyone
How often does the radiator fan blades break on one of these rigs
Its an 03 dutchstar c7 cat 330 hp.
I was going thru a small city just creeping along and I heard this thump and the motorhome started shaking. I pulled over and discovered that one of my fan blades broke off. Which of course threw it out of balance and shook like crazy..
Has anyone don e that one yet.????

How big a job is that going to be

bobpam54,
Yes Sir, it's quite normal. Maybe not that often but, normal. I know of at least three CAT owners, different coaches, different years and different models, all had fan blades break off. One of them had almost all of them break off and cruise around like that for quite some time before he actually knew it.

My son worked in an RV Service Center in San Diego for a year and saw quite a few broken fan blades come in on diesels. Not all were CATS either. They're a form of a plastic and, as we all know, plastic will eventually harden some and have less flex. When it does that, it starts to get brittle. You know the rest of the story.
