How to align distributor rotor
2003 chevy s10 abs control module location
If the gear on the bottom of the distriubutor has been removed, it has a mark and can be put 180 degrees out. Install the destributor with the rotor bug pointer exactly where # 1 is on the cap. This will put the engine back in time, there are no adjustments. If you get it back only 1 tooth off, there will we a check engine light.
