Detailed Description

This Dorman harmonic balancer, part number 594-586, is engineered for vehicles that require a direct-fit crankshaft vibration damper. It is used on a wide range of Ford, Lincoln, and Mercury models, including 2001-2011 Ford Crown Victoria, 2001-2011 Lincoln Town Car, 2001-2011 Mercury Grand Marquis, 2001-2004 Ford Mustang, 2002-2004 Ford Explorer, and 2009-2010 Ford F-150. The steel body and bonded rubber construction are selected to help maintain balance and reduce vibration transfer in the engine assembly.

This part cross-references Ford 1W7Z6312A and PowerBond by Dayco PB1516N for the same application.

What It Helps Address

• Engine vibration felt through the crankshaft and accessory drive
• Wear or failure of the original harmonic balancer rubber bond
• Noise or imbalance from a deteriorated crankshaft damper
• Serpentine belt drive issues related to a damaged pulley surface
• Service replacement needs on high-mileage Ford, Lincoln, and Mercury engines

Installation Notes and Tips

Verify engine version and application details before installation, especially on 2005-2009 Ford F-250 and 2005-2008 Ford F-150 models with Romeo engine versions. Confirm the 6-groove serpentine belt layout, 1.25 in. mounting hole diameter, and keyway configuration before assembly. Use the correct service procedure for crankshaft balancer removal and installation to avoid damage to the crankshaft or accessory drive components.

Quality Assurance

Dorman builds this replacement harmonic balancer to meet stringent standards for tensile and impact strength. The design focuses on durability and vibration control for long-term service in compatible Ford, Lincoln, and Mercury engine applications.
