Volvo Engine Rocker Arm - Genuine Volvo 32339084

Product Information

An Engine Rocker Arm is a critical component in the valve train of an internal combustion engine. It acts as a lever that transfers the camshaft’s rotational motion into the up-and-down motion needed to open and close the intake and exhaust valves.

When the camshaft lobe pushes one side of the rocker arm, the other side presses down on the valve stem, allowing air-fuel mixture in (intake valve) or exhaust gases out (exhaust valve).

• Tapping or clicking noise from the engine – caused by excessive clearance or a loose/broken rocker arm.
• Engine misfire or rough idle – valves may not open properly, leading to incomplete combustion.
• Loss of power/poor acceleration – improper valve timing reduces engine efficiency.

About Genuine Volvo

The original parts used by Volvo to build your car are available as replacement parts under the “Genuine Volvo” brand. Manufactured under the direction of Volvo, expect excellent quality and a premium price since these parts are exclusively available through the Volvo Dealership network.

You may not realize this, but the parts that make up your Volvo are not necessarily manufactured by Volvo. No cause for concern, as Volvo designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Volvo for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Volvo parts box and find an OEM branded part inside, simply with the addition of a Volvo logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
