Drive Belt Tensioner - automatic tensioner for the front-end accessory drive on the AJ20 Ingenium petrol engine range.

A spring-loaded pivoting arm carrying an idler pulley bears against the V-ribbed serpentine belt, holding belt tension constant as the belt beds in and stretches, and damping the torsional pulses fed into the belt by the crankshaft. Consistent tension keeps the belt-driven ancillaries turning without slip and stops the belt tracking off its pulleys.

Applies to the petrol Ingenium range only - 1.5L three-cylinder, 2.0L four-cylinder and 3.0L six-cylinder. A failing tensioner typically presents as belt squeal on cold start, a visibly oscillating tensioner arm with the engine running, or accelerated wear along the belt edges.

Frequently asked questions

What is the LR161768G drive belt tensioner for?
The LR161768G drive belt tensioner is the automatic tensioner for the front-end accessory drive on AJ20 Ingenium petrol engines. A spring-loaded arm and idler pulley hold the serpentine belt at constant tension, keeping the belt-driven ancillaries turning without slip and damping crankshaft pulses in the belt.
Which engines does this tensioner fit?
This tensioner fits AJ20 Ingenium petrol engines only, covering the 1.5L three-cylinder, 2.0L four-cylinder and 3.0L six-cylinder petrol units. It is not for diesel engines, so confirm your engine is petrol AJ20 before ordering across models like the Defender L663, Velar and Range Rover L460.
What are the signs the belt tensioner is failing?
Signs of a failing drive belt tensioner include a rattle or squeal from the front of the engine, a visibly slack or fluttering belt, or bearing noise from the idler pulley. A worn tensioner typically lets the belt slip, which can affect the belt-driven ancillaries.
Which models use this tensioner?
This tensioner fits petrol AJ20 applications on the New Defender L663, Discovery 5, Discovery Sport, Range Rover L405 and L460, Range Rover Sport L494 and L461, Range Rover Evoque L551 and Range Rover Velar. Confirm your engine is a petrol AJ20 unit to verify fitment.
