  Q: How to replace the distributor and set the ignition timing on a 1.0L engine on Chevrolet Metro?

  A: The Distributor replacement process requires disconnecting both the negative (-) Battery Cable and Distributor electrical connector. Two screws hold the Distributor Cap in place so remove them before removing the cap. Use a marker to note the Distributor housing location on the cylinder head before removing the two Distributor flange bolts and housing component from this surface. Begin by marking the Distributor coupling position on the Distributor housing then inspect the Distributor Cap and rotor for cracks, terminal corrosion, or wear before replacing any damaged parts. Use j 22794 Spark Plug port adaptor (J 22794) to set the Distributor position if any orientation becomes lost. To reach top dead center (TDC) on the compression stroke of cylinder number 1 you must remove the fi fuse from the fuse and relay box along with removing the number 1 Spark Plug before installing the j 22794 Spark Plug port adaptor and compression gauge in the Spark Plug cavity. Check the compression reading on the gauge because tdc marks its peak point. Begin by aligning the Crankshaft Pulley timing mark with the timing indicator zero (0) position while the rotor faces the number 1 cylinder. Then install the Distributor. Reinstall the number 1 Spark Plug with a torque of 28 n.m (21 lb ft) while the j 22794 Spark Plug port adaptor and compression gauge have been properly removed. Reinstall the fi fuse into the fuse and relay box while setting the ignition timing. The Distributor housing installation requires the (1,3) Distributor coupling marks to align for proper distribution housing placement onto the cylinder head. Keep the Distributor marks as they were set during removal. First place the Distributor flange bolts in place without applying complete torque followed by installing a new Distributor Cap seal to the Distributor Cap and fastening the cap with its two screws. Perform the following installation steps before reconnecting the negative (-) Battery Cable. Tighten the negative (-) Battery Cable-to-negative (-) battery terminal retainer to 15 n.m (11 lb ft). Complete ignition timing calibration for the 1.0l power unit.
