3.0 3.2 SI6 Alternator One-Way Decoupler Pulley
Genuine Volvo 31316804 - 140959
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 Genuine Volvo pulley will get you back on the road.

Many may not know this but Volvo in Latin roughly translates to "to roll". The company was founded back in 1927 by Assar Gabrielsson and Gustaf Larsson as a spin-off from ball-bearing manufacturer SKF. While the Volvo logo looks like the biology symbol for male, it's really the Swedish symbol for Iron. With a nod to its heritage in alloys, Volvo chose a logo that depicted a ring bisecting at one o’clock. Today Volvo is known around the world as one of the most iconic brands known for safety, longevity, and its enthusiast following.
