Cloyes 9-5479 Engine Timing Belt Tensioner - Front

Cloyes 9-5479 Timing Belt Tensioner

The Cloyes 9-5479 engine timing belt tensioner is built for specific front-engine applications that require stable belt tension and consistent timing belt control. It is designed for Ford Focus, Ford Escape, Ford Escort, Ford Contour, Mercury Cougar, Mercury Mystique, and Mazda Tribute applications where proper belt tracking matters.

Key Features

• Specific-fit engine timing belt tensioner for selected Ford, Mercury, and Mazda vehicles
• Helps maintain constant timing belt tension during crankshaft rotation
• Reduces belt noise and belt flapping
• Nylon/aluminum construction for durable service
• Pulley included for a complete tensioner assembly
• Black/gray finish
• CAD designed and manufactured with advanced materials
• Extensively tested for function and durability

Detailed Description

Cloyes 9-5479 is an OE-style timing belt tensioner engineered to keep the timing belt properly tensioned throughout engine operation. By helping absorb changes in belt tension, it supports smoother belt movement and more consistent transmission efficiency over the belt’s service life. This part cross-references Ford OE number F8CZ6K254AA for the same application.

Compatible With 2001-2004 Ford Escape, front; 2000-2004 Ford Focus, front; 2001-2004 Mazda Tribute, front; 1998-2003 Ford Escort, front; 1999-2002 Mercury Cougar, front; 1998-2000 Ford Contour, front; and 1998-2000 Mercury Mystique, front. The Cloyes 9-5479 is a direct-fit service part for these timing belt systems and is commonly selected during timing belt maintenance on Ford Focus and Ford Escape models.

What It Helps Address

• Timing belt slack caused by worn tensioner components
• Noise from a loose or unstable timing belt
• Belt flapping during engine operation
• Uneven belt tracking that can affect timing system performance
• Wear from aging pulley and tensioner components

Installation Notes and Tips

Replace the timing belt tensioner during timing belt service to keep the belt system working as a matched set. Cloyes also recommends replacing belt idlers at the same time when the belt is replaced. Verify application details by year, make, model, and front position before installation. Use the vehicle service procedure and timing marks specific to the engine.

Quality Assurance

Cloyes designs and manufactures timing components using CAD-based engineering and advanced materials, then tests each part for function and durability to support reliable performance in service.
