It's been stated before on here by many to check and modify your fans if needed on your older LMTV's. I had a friend a couple of weeks ago have his fan go out enroute to a parade 80 miles from his house. The tow bill was 1400 dollars for what could have been a $20 repair beforehand. This is the 3rd fan that I have repaired. Check your fan and if it has allen head bolts holding it on, it needs to be replaced with a newer clutch and fan OR , cheaply modified to prevent failure.
The original setup has a rubber doghnut that allows the fan to spin if needed. This will deteriorate and fail eventually and it will ruin your fan. Best practice is to remove it and install eight 3/16 bolts and nuts in existing holes to eliminate any chance of failure. In my friends case I happen to have a modified fan assembly to replace his bad one.

Modified with the rubber removed and bolts in the existing factory holes.

I use leftover 3/16 aircraft grade bolts and locknuts from my Aircraft Maintenance days.
