G4 Alternator Belt (Ribbed,6 Grove, 1125mm) - 1.6

This 6-rib v-ribbed alternator belt (6PK1125) is a factory-correct replacement for a wide range of Volkswagen petrol models. Measuring 1125 mm long with 6 ribs, it is engineered to transmit drive smoothly from the crankshaft pulley to the alternator, ensuring consistent battery charging and reliable electrical performance.

The belt’s ribbed profile increases contact area and grip, reducing slip under load and helping to prevent squeal or glazing. Over time, auxiliary belts can stretch, crack, or harden from heat and age—leading to charging faults or warning lights. Replacing the belt restores correct tension and protects the alternator and associated pulleys from premature wear.

Ideal for routine servicing or when renewing related components, this belt matches OE dimensions for correct alignment across all listed applications.
