2018 Mack GU813 MP8
The fan belt blew up a few weeks ago and took out the fan clutch harness. Asked Mack if I could just get the harness and they said no. We replaced the fan clutch and everything ran fine till yesterday. Fan belt blew up again and took out the fan clutch harness again. Fan clutch P/N: 24437931. My 2 questions:
1. Is it possible to just get the fan clutch harness rather than dropping another $1,600 for a fan clutch?
2. What would cause the belt to blow again? Tensioner has good tension and no play, idlers/pulleys roll fine and don't have any play either. A sister truck to this one had a problem with the alternator belt blowing every other day which ended up being bad motor mounts. This trucks motor mounts look fine. What else should I look at?
