G4 Alternator Belt (Ribbed, 6 Grove, 1538mm) - 1.6

This 6-rib v-ribbed alternator belt is designed to drive the alternator and auxiliary components on Volkswagen petrol engines. With a total length of 1538 mm and 6 ribs, it matches the factory belt specification used on selected VW Bora and Golf Mk4 models, ensuring correct fit, alignment, and long service life.

The belt transfers engine rotation from the crankshaft pulley to the alternator, allowing the battery to charge and the electrical system to operate correctly. On vehicles where the auxiliary drive also runs additional components, maintaining the correct belt length and rib count is essential to prevent slip, squeal, or premature wear.

Over time, auxiliary belts can crack, glaze, or stretch, leading to charging faults, warning lights, or noisy operation. Replacing the belt as part of routine maintenance—or whenever related pulleys or tensioners are changed—helps protect the alternator and keeps the auxiliary drive running smoothly.
