Installation Notes and Tips

Verify distributor number and engine application before installation, especially on Saab 900 and Saab 9000 models with distributor-number notes. Confirm the rotor uses a push-on mount and inspect the distributor cap, shaft, and terminals for wear before reassembly. Replace the rotor if the contact surface is damaged, burned, or loose on the distributor shaft.
