Dorman 594-716 Engine Harmonic Balancer

Engine Harmonic Balancer Overview

This Dorman engine harmonic balancer is a direct replacement designed to absorb engine vibration and support smoother operation. It uses a stress-resistant rubber bond and ductile steel construction for durability in demanding service.

Compatible with a wide range of Chevrolet, GMC, and Cadillac applications, this part number 594-716 is built for vehicles that use a serpentine drive belt and a keyed balancer design. It also includes degree markings for timing reference during service.

Key Features

• Direct replacement harmonic balancer for engine vibration control
• Stress-resistant rubber bond helps absorb torsional vibration
• Ductile steel construction adds tensile and impact strength
• Keyway design with degree markings for service reference
• Three-groove pulley layout for serpentine belt applications
• Black finish for a clean OE-style appearance

Detailed Description

Dorman part number 594-716 is an engine harmonic balancer built to replace the original unit on select Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade applications, along with other listed GM trucks and vans. The bonded rubber element is engineered to reduce vibration transfer, while the ductile steel body provides the strength needed for long-term engine service. This makes it a practical choice when restoring balance control on GM V8 applications that require a keyed, three-groove serpentine balancer.

This part cross-references GM 12620312 for the same application.

What It Is Used For

• Reducing crankshaft vibration transmitted through the accessory drive
• Replacing a worn or separated harmonic balancer
• Restoring timing reference visibility with degree markings
• Addressing belt drive noise or imbalance-related engine vibration
• Supporting proper operation on listed Chevrolet and GMC engine applications

Installation Notes and Tips

Verify the inside diameter, outside diameter, depth, keyway type, and pulley groove count against the original part before installation. Confirm serpentine belt routing and engine application details for the specific Chevrolet Silverado 1500, GMC Sierra 1500, or Cadillac Escalade fitment listed. The package contents include the harmonic balancer and an instruction sheet; bolts, washers, and center bolt are not included.

Quality Assurance

Dorman designs this harmonic balancer as a direct replacement part with materials selected for vibration control and durability. The ductile steel construction and bonded rubber element support reliable service in engine applications that demand stable crankshaft damping.
