Installation Notes and Tips

Verify the OE number on the original distributor vacuum advance before installation, especially on emissions-specific Chevrolet, Oldsmobile, and Pontiac applications. Confirm the vacuum hose routing and connector style match the existing distributor setup, and inspect the vacuum line for cracks or leaks before replacing the unit. Use the vehicle’s emissions calibration and distributor number to confirm the correct VC-202 application.
