- Alternator (from donor vehicle)
- Power Steering Pump(from donor vehicle)
- A smooth water pump pulley is required (GM part number 10085760 or 19418445)
- Donor engines should have the correct pulley. (The pulley with flanges does not work)

- Six-rib belt, See our included installation instructions for suggested lengths and Gates part numbers.
- Complete Gates belt chart available here. GATES BELT CHART
- Alternator rating and PS pulley diameters can change suggested lengths.
- Always check tensioner marks for correct fitment.
- A tall deck engine will require a belt that is about 1" longer.
- A new thermostat housing may be needed to allow the upper radiator hose to clear the alternator.
- The Chevelle shown is using a swivel-neck housing.
- Upper radiator hose will probably need to change, but your vehicle's stock big-block lower hose, should work.
