Cloyes 9-5124 Engine Timing Belt Tensioner - Front

Cloyes 9-5124 Timing Belt Tensioner

The Cloyes 9-5124 engine timing belt tensioner is built for specific Nissan, INFINITI, and Mercury applications that require stable belt control at the front of the engine. It helps maintain consistent timing belt tension through crankshaft rotation, reducing belt noise and belt flutter while supporting smooth power transfer across the belt service life.

Key Features

• Steel construction for durable engine bay performance
• Pulley included for direct timing belt service replacement
• Specific-fit design for application accuracy
• Gray finish
• CAD-designed and manufactured with advanced materials
• Extensively tested for function and durability

Application Details

This timing belt tensioner is engineered for front-mounted timing belt systems on vehicles such as the Nissan Frontier, Nissan Xterra, Nissan Pathfinder, Nissan Maxima, Nissan Quest, INFINITI QX4, and Mercury Villager. It is also listed for additional Nissan applications including the D21, Pickup, 300ZX, 200SX, and INFINITI M30. Part number 9-5124 is a direct-fit service part for these specific applications, and it cross-references Dayco 95124 for the same application.

What It Helps Address

• Timing belt slack caused by wear in the tensioner assembly
• Belt noise during engine operation
• Belt flapping at higher engine speeds
• Uneven belt tension across crankshaft rotation
• Reduced timing belt service performance from worn support components

Installation Notes

For timing belt service, replace the belt tensioner and belt idler components together when the belt is replaced. Cloyes recommends checking the full timing system during service to maintain proper belt tracking and tension. Verify application details by year, make, model, and front position before installation. Part number 9-5124 is a specific-fit component, so correct vehicle matching is important for proper operation.

Quality Assurance

Cloyes manufactures this tensioner using CAD-based design and advanced materials, then tests each part for function and durability to support consistent performance in service.
