Dorman 594-710 Harmonic Balancer

The Dorman 594-710 harmonic balancer is a direct replacement for select GM applications that use a 7-rib serpentine belt. It uses a stress-resistant rubber bond to absorb engine vibration, while ductile steel construction adds tensile and impact strength for long-term durability.

Compatible With Buick LaCrosse, Buick Regal, Chevrolet Malibu, Chevrolet Impala, Pontiac G6, Saturn Aura, and Saturn Vue applications listed below, this harmonic balancer supports accurate crankshaft vibration control and timing reference. The black finish, degree markings, and keyed design help support proper installation and service alignment.

• Crankshaft pulley wobble or imbalance
• Timing reference issues when degree markings are needed
• Noise or belt tracking concerns related to balancer wear
• Damage from cracked or deteriorated harmonic balancer components

Installation Notes and Tips

Verify the engine uses a 7-rib serpentine belt before installation. Confirm the inside diameter, outside diameter, depth, and keyway style match the original part. Inspect the crankshaft snout, pulley alignment, and belt condition during replacement. Because bolts and washers are not included, reuse or source the correct fasteners separately as required by the vehicle service procedure.
