Installation Notes and Tips

Inspect the distributor bore and sealing surface before installation. Remove any old residue, dirt, or hardened seal material so the new O-ring seats evenly. Verify the distributor application against the vehicle year and model before service, especially on Mazda 626, Mazda MX-6, Ford Probe, Mazda Protege, and Mazda Protege5 vehicles. Confirm the O-ring dimensions match the original seal before reassembly.
