Important installation notes

• When using with an early short water pump style engine, install AF64-3005 spacer
• If your engine is equipped with power steering, expect modifications to the power steering bracket to fit
• The pump requires the use of AF64-3010 pulley
• Aeroflow does not specify belt lengths due to the wide range of possible belt configurations on modern setups
• To determine the correct belt length for your vehicle, bolt the Gilmer kit on, then measure around all three pulleys with the alternator at the lowest adjustment point

Pro tip: purchase the appropriate Gilmer kit for your application, install it on the engine, and then accurately measure the minimum belt length required. This approach ensures a secure fit and prevents belt slippage or premature wear in your Holden V8 setup.
