Product Information

The Holley Accessory Drive Kit consists of various components that are necessary for the installation and operation of the accessory drive system in a vehicle.

The dimensions for the Holley Accessory Drive Kit are not provided in the user manual.

Product Usage Instructions

1. Before painting or coating any components, ensure that the mating surfaces of the alternator and A/C compressor mounting brackets are bare metal. This allows for a ground path from the accessories’ mounting feet to the engine block and battery’s negative terminal.
2. Refer to the provided parts list for a detailed description of each component included in the kit.
3. For A/C installation, follow the instructions provided for Holley P/N 20-160 regarding A/C compressor and belt installation. Install the A/C bracket in the standard alignment position.
4. When installing the alternator, torque the M10 bolts to 36 ft./lbs. Connect the included 197-400 plug into the alternator and  then connect the yellow wire to a switched voltage that is on whenthe key is in the run position. If the vehicle has a charge indicator light, the yellow wire can be connected to that circuit.
5. For power steering pump/reservoir installation, install the 198-207 power steering AN adapter/tube and assemble accordingly.
6. Torque the M8 bolts to 18 ft./lbs. and the banjo bolt to 25 ft./lbs.
7. When installing the power steering pulley, use an installation tool that can be rented at most auto parts stores. Ensure the pulley bore face is flush with the end of the pump shaft to prevent damage to the pump internals.

Introduction

Holley’s accessory drive kits offer clean, economical mounting of all LS engine accessories. These brackets pull all accessories in more toward the engine when compared to the original LSA accessories giving more clearance to swap applications and overall cosmetic appeal. These brackets look truly at home on the LSA engine as if they came from the factory this way. Holley’s complete accessory drive systems come with virtually everything needed for installation, from the accessories to the pulleys and even the belt.
Note : This drive works with the original LSA damper/pulley and similar aftermarket versions.
IMPORTANT NOTE IF PAINTING COMPONENTS: The alternator and A/C compressor ground through their mounting brackets. If painting or coating the brackets, the mating surfaces must all be bare metal allowing a ground path from the accessories’ mounting feet to the engine block and ultimately the negative terminal on the battery.

Parts List

A/C Installation

Install A/C bracket in the standard alignment position at this time.
NOTE : For details on A/C Compressor and belt installation, see instructions for Holley P/N 20-160.

Alternator Installation

NOTE : Torque M10 bolts to 36 ft./lbs.
Helpful hint : When wiring the alternator, install the included 197-400 plug into the alternator. Next, connect the yellow wire to switched voltage that is “on” when the key is in the run position. If the vehicle has a “charge indicator light”, the yellow wire can be connected to that circuit.

NOTE : Torque M10 bolt to 36 ft./lbs.

P/S Pump/Reservoir Installation:
Install the 198-207 power steering AN adapter/tube and assemble at this time.

Step Four
Torque M8 bolts to 18 ft./lbs. and banjo bolt to 25 ft./lbs.

NOTE : Torque M10 bolts to 36 ft./lbs.

The P/S pulley must be installed using an installation tool that can be rented at most auto parts stores. Incorrect installation of this pulley may damage the P/S pump internals. When installed, the pulley bore face should be flush with the end of the pump shaft.

Accessory Belt Installation

NOTE : Torque M10 bolts to 36 ft./lbs.

NOTE : Torque M10 bolts to 36 ft./lbs.

NOTE : Torque M10 bolts to 36 ft./lbs.

HELPFUL HINT: When installing the belt, route around all the pulleys except the water pump pulley. While fully rotating the tensioner arm, slip the belt on the smooth water pump pulley last.
Use the serpentine belt supplied if using ALL included Holley accessories and supplemental parts.

SC Belt Installation:

NOTE : Torque M10 bolt to 36 ft./lbs.

NOTE : Torque M10 bolts to 36 ft./lbs.

HELPFUL HINT: When installing the belt, route around all the pulleys except the large idler pulley. While fully rotating the tensioner arm, slip the belt on the smooth idler pulley last.

Belt Length Calculation

NOTE : If you are NOT using all the Holley accessories supplied, or have changed the original crank or any accessory’s pulleys, you will have to measure to find the correct belt length.

To acquire this measurement, perform the following:
After all brackets and accessories are installed, route masking tape or string around the belt path. Leave the tensioner in the un-sprung position for this measurement. Mark or cut the tape/string to length and remove from the pulleys. Subtract 1 1/8” (28 mm) from the measured length to compensate for the un-sprung tensioner position. You will need to convert belt length to millimeters if measured in inches (inches X 25.4 = mm). Go to any auto parts store and ask for a 6PK0000 belt with the “0000” being the length in millimeters. For example, if you measured 2493 mm and then subtracted 28 mm, you would get 2465 mm, and the part number would be 6PK2465.
