Ilmor PV06709 Alternator Belt
Keep your charging system running quietly and efficiently with the Ilmor PV06709 Alternator Belt. Built to factory specifications, this serpentine belt delivers the correct length and rib profile to maintain proper tension and smooth operation across the alternator and accessory drive.
As belts wear, they can slip, squeal, or lose grip—leading to inconsistent voltage and reduced system performance. Replacing it with the proper OEM belt helps restore steady charging output and keeps your engine running the way it was designed. The PV06709 is constructed for marine use, with materials that hold up to heat, moisture, and constant vibration inside the engine compartment.
Designed as a direct replacement, this belt installs easily and maintains proper alignment on compatible Ilmor engines, helping reduce wear on pulleys and connected components.
