FAQ
Will the FPE-34660-BLK pulley work with both 5.9L and 6.7L Cummins engines?Yes. This Fleece fan drive pulley is designed for 2003-2012 Ram 2500/3500 trucks equipped with either the 5.9L (2003-2007) or 6.7L (2007.5-2012) Cummins diesel engine, and replaces OE pulley 4930580.
Do I need a different belt when installing this pulley?
No belt change is typically required. The pulley maintains the correct 6.965" outside diameter and stock belt routing. As long as your belt and other front-drive components are in good condition, you can reuse the existing belt.
Is this pulley compatible with other Fleece front drive and cooling upgrades?
Yes. The FPE-34660-BLK works great with Fleece upper fan idlers, coolant bypass kits, and cooling fan pigtails. For example, combine it with the FPE-34657-BLK-SPK upper fan pulley idler and FPE-CLNTBYPS-CUMMINS-0712 coolant bypass kit for a more complete front-drive and cooling system package.
Is any special tooling required for installation?
Installation is similar to replacing the factory fan drive pulley. Basic hand tools and a way to safely hold the fan hub while loosening and tightening fasteners are generally all that is required. Always follow OEM service procedures and torque specifications.
Does this product include a warranty?
Fleece Performance typically backs their components with a limited parts warranty. For the most current warranty terms and assistance, refer to Fleece Performance’s official documentation or contact CPP Diesel before purchase.
