What is a front-end accessory drive system?
The front-end accessory drive, or FEAD, transfers power from the engine to belt-driven accessories such as the alternator, A/C compressor and, depending on the application, the water pump or power steering pump. The system typically includes a serpentine belt, tensioner and one or more pulleys working together to maintain proper belt routing, alignment and tension.
What are common signs of accessory drive wear?
Common signs include belt squeal or chirping, visible cracking or fraying, excessive tensioner movement, pulley noise, belt misalignment, or a rough-feeling pulley bearing. Because these symptoms can have several causes, the entire accessory drive system should be inspected before replacing an individual component.
Why should the belt, tensioner and pulleys be inspected together?
Accessory drive components operate together and are exposed to the same mileage, heat and operating conditions. A worn tensioner or pulley can affect belt alignment and tension, while a worn belt can contribute to noise and slip. Inspecting the complete system helps identify related wear that could affect the new component or lead to another repair.
What is included in a Cloyes serpentine belt kit?
Contents vary by application, but Cloyes serpentine belt kits combine the application-specific belt, tensioner and required pulleys in one package. Kits also include an engine-specific belt-routing diagram to support accurate installation. Use the Cloyes Part Finder to verify the components included for a specific vehicle.
What are the benefits of a fabric-backed EPDM belt?
The fabric backing helps control belt engagement as accessory loads change, including during A/C compressor cycling and cold starts. It also helps reduce noise and vibration, protect against abrasion and distribute heat across the belt surface. EPDM construction provides resistance to cracking and wear in high-mileage and demanding applications.
How do I find the correct accessory drive kit or component?
Search the Cloyes Part Finder by year, make, model and engine. Accessory drive components are application-specific, so confirm the complete vehicle and engine information before installation rather than selecting a part by appearance or dimensions alone.
