Range Rover Sport L461 3.0 plug-in hybrid (P440e / P510e / P550e): auxiliary belt & tensioner check

Engine · Range Rover Sport L461 (2022 on) · 2023 on

How often: every 21,000 mi or 2 yrs, whichever comes first. On many of these engines the auxiliary belt drives the water pump and alternator; a snapped belt can be pulled into the timing belt cover.

Work safely: support the vehicle on axle stands, never a jack alone; let it cool first. Check figures against your workshop manual. You do this work at your own risk.
