Installation

Holley® - Aluminum LS High Mount A/C Compressor Accessory Drive Bracket Installation Instructions

Holley’s kits supply the required brackets and hardware needed for installation, but allow you to choose the source for supplemental accessories and components that are often already on the donor engine or host vehicle. Whether sourcing from the salvage yard, the local auto parts store, your GM parts dealer, or Holley, you pick the accessories that match your needs and budget!

When you need to repair your climate control system you can battle the traffic and stand in line at the auto parts chain store, only to be told that what you need is out of stock and has to be ordered. And even if they have the parts can you be assured of the quality? Do you recognize the name on the box? And how do you know if you’re getting the best price?

You won't have those concerns with the replacement climate control parts offered on our website. They carry only top name products from well-known OE and aftermarket suppliers. In fact, many of the manufacturers they deal with are suppliers to the vehicle manufacturers, so the parts you get may be the same as the ones that came on your car or truck. In their online store you can find all the major A/C system components like compressors, condensers, evaporators, accumulators and receiver-driers, as well as the no less important small parts like pressure and temperature switches, seals, expansion valves and orifice tubes. They are also your source for heating system parts like heater cores, blower motors, resistors and cabin filters.
