Dayco 6100672 serpentine belt for the 2010-2016 Mack MRU and other vehicles drives the fan and water pump from the engine. This DAYCO drive belt is sold one per listing; one belt is all the fan and water pump drive takes.
A belt that is cracked, frayed, glazed or missing rib material, or one that squeals, can mean it is due for replacement. With the engine off and cool, look over the ribs for damage first. A squeal can also come from a pulley or tensioner, so find the cause before buying a belt.
This belt is a direct-fit replacement for the 2010-2016 Mack MRU, the 2011-2016 Mack LEU 6-cylinder 10.8L and the 2016 Mack LR600 6-cylinder 10.8L.
