Belt Tensioner for the V8 EFI petrol engine, part of the ancillary (serpentine) drive belt system.

The tensioner pulley bears against the auxiliary drive belt and maintains correct running tension on the belt that turns the engine ancillaries. Consistent tension keeps the driven components turning without slip and reduces premature belt wear and noise.

Frequently asked questions

What does the ERR3440 belt tensioner do on the V8 EFI?

The ERR3440 belt tensioner maintains correct tension on the ancillary (serpentine) drive belt of the V8 EFI petrol engine. Its pulley bears against the belt that turns the engine ancillaries, keeping them driven without slip and reducing belt wear and noise. It's the auxiliary belt tensioner, not the timing tensioner.

Which V8 Land Rover models use this belt tensioner?

This ancillary belt tensioner fits the V8 EFI petrol engine in the Land Rover Defender (4.0L V8, with air conditioning), Discovery 1 (1989-1998, VIN FA393361 to WA799999, with A/C) and Range Rover Classic (1992-1994, with power steering). It's made by Dayco, and APV1005 is a listed alternative.

What are the signs the belt tensioner needs replacing?

A worn belt tensioner typically shows as a squealing or chirping auxiliary belt, a rattling pulley bearing, or visible belt wear. If the pulley doesn't spin smoothly or the belt slips, the tensioner is usually the cause. It's worth replacing the tensioner and belt together on the V8 EFI.
