Genuine Part
Genuine: Original manufacturer part. This product is the original part designed and produced by the vehicle manufacturer.
Drive Belt - ISG - V-belt in the front-end accessory drive of the 3.0L Ingenium six-cylinder petrol engine, driving the belt-integrated starter generator (ISG).

The belt transmits torque between the crankshaft pulley and the starter generator, both for belt-driven charging and for engine restart, so it is loaded in both directions rather than in drive only. Glazing, cracking or fraying at the belt edges are grounds for replacement; a slipping belt typically shows up as restart hesitation and charging faults.

Fitted to the 3.0L AJ20P6 Ingenium petrol engine, including PHEV builds.

Frequently asked questions

What does the ISG drive belt do?
The ISG drive belt transmits torque between the crankshaft pulley and the belt-integrated starter generator on the 3.0L Ingenium six-cylinder petrol engine. Because it drives charging and also spins the engine for restart, it's loaded in both directions rather than in drive only.
What are the signs the ISG belt needs replacing?
Glazing, cracking or fraying at the belt ribs is the usual sign the ISG belt needs replacing, often with squeal on restart or start-stop cycles. A belt in this position works harder than a plain accessory belt, so it's checked at every service.
Which vehicles use this ISG drive belt?
This ISG drive belt fits the 3.0L AJ20P6 petrol engine (High and PHEV) on the New Defender L663, Discovery 5, Range Rover L405 and L460, Range Rover Sport L494 and L461, and Range Rover Velar. Confirm your engine and VIN before ordering.
