V-Belt Fan Belt, 0.51 in Width × 31.50 in Length SKU: QT4456

This V-belt fan belt transmits rotational power from the crankshaft to the cooling fan, helping maintain engine temperature under heavy use.

Made from reinforced rubber with internal cords, it resists stretching, slipping, and wear even in demanding conditions.

• 0.51 in width × 31.50 in length (13 mm × 800 mm)
• AVX13 profile for better flexibility and heat dissipation in fan drive systems
• Reinforced internal cords for dimensional stability and strength
• Durable rubber compound resists heat, oil, and environmental damage

Installation Tip: Loosen the belt tensioner or alternator mount, route the belt around all pulleys (fan, crank, idler), then reapply tension so there is approximately ½ in deflection over a 10 in span.

This fan belt offers a reliable replacement to help your cooling system perform consistently even under tough field conditions.
