Product Description

When Volvo was developing their "short six" 3.2i and 3.0 T6 engines for transverse installation in engine bays, the accessory belt drive was relocated from the front (left) end of the engine to the rear (right) end, above the transmission. Putting belt-driven accessories like the water pump and A/C compressor in this free space above the transmission makes the six-cylinder SI6 even more compact than the old five-cylinder.

Both the primary accessories and the alternator are driven by this "R.E.A.D." (Rear Engine Accessory Drive) via one-way, freewheeling clutches in the pulleys, allowing the belts and accessories to gradually spin down when RPMs drop off. The extra second or two the accessories spend coasting down allows them to extract a little more energy from their own inertia, saving a bit of fuel while also subjecting the belts to gentler shock loads.

If you're hearing pulley bearing failure noises like squeaks or rattles or grinds, and especially if those noises are slightly delayed after revving the engine, these pulleys are worth replacing. This INA (the Original Equipment Supplier to Volvo) pulley will get you back on the road.

Potential Product Fitment Issues

A special tool is needed to unscrew the pulley while counterholding the shaft. Use either IPD # 140962 or (if also performing alternator service) IPD # 140960.
