Serpentine System Install On LS Engine - Serpentine Solutions - Tech

Included in the kit is the power steering fluid reservoir and hose kit that connects to the pump and mounts via the aforementioned steel bracket.

The alternator attaches to the bracket using the provided hardware.

This is the harmonic balancer (PN 12620556) that is recommended for most applications and brings the crank pulley in line with the other pulleys in the kit.

The A/C compressor uses a separate serpentine belt than the rest of the components to minimize noise, vibration, and harshness, aka NVH, and to ease installation or removal of said items from the kit. Trucks not running an A/C system can leave off the associated bracket, compressor, tensioner, and belt.

Here's the kit all buttoned up with both belts installed. Note the routing of the longer serpentine belt that drives the water pump, alternator, and power steering pump off the harmonic balancer via the two tensioner pulleys.
