Dayco Serpentine Belt P/N:5080980
Dayco 5080780 serpentine belt for the 2010-2011 International Workstar 7600 12.5L and other vehicles carries crankshaft power to the engine's belt-driven accessories. Depending on the engine, this Dayco serpentine belt turns the alternator, fan and air conditioning.
A squeal or chirp from the engine, cracked or glazed ribs, or accessories that turn slowly can mean the belt is worn, though a weak tensioner or a misaligned pulley can be behind the same signs. Each engine runs a single belt.
The vehicles this belt fits include the 2008-2010 Autocar LLC. Xpeditor 6-cylinder 10.8L, the 2008-2010 Autocar LLC. Xpeditor WX 6-cylinder 10.8L and the 2010-2011 International Workstar 7600 12.5L. If yours is not one of these, open the Buyer's Guide tab to check your exact model and engine.
