Cloyes Engine Timing Crankshaft Sprocket P/N:S1137
Cloyes S803 timing crankshaft sprocket for the 2003-2006 Jeep Wrangler 4-cylinder 2.4L and other vehicles drives the timing chain from the crankshaft so engine timing stays precise.
A rattle from the front of the engine or timing-related running problems can mean this sprocket is worn, though a stretched timing chain or a weak tensioner can be behind the same signs. Timing service goes best when the chain, tensioners, guides and sprockets are replaced together.
The 2002-2005 Jeep Liberty 4-cylinder 2.4L and the 1996-1997 Dodge Grand Caravan 4-cylinder 2.4L are among the other vehicles this sprocket fits. If your car is not named here, look up its year and engine in the "Vehicles it fits" section.
