  Q: How to overhaul the distributor on GMC Safari?

  A: For Distributor overhaul start by removing engine covers. Adjust the white paint mark on the Distributor's bottom stem to fit the pre-etched hole on the gear base. Take marks on the Distributor driven gear and Distributor shaft with marks on the rotor holes because improper installation will create a no-start scenario that potentially damages the engine. For correct placement of the v6 rotor segment follow the indicated position. If misaligned, replace the Distributor. Free the Distributor's two screws from the rotor unit after removing the rotor while recording the rotor screw hole locations and rotor locator pin hole positions. Prepare the cmp sensor by removing its two different screws while discarding them before aligning the vane wheel's square-cut opening with the cmp sensor. A dimple located below the roll pin hole on one side of the gear serves as an indicator for correct Distributor reassembly alignment. Place the Distributor drive gear inside a v-block or similar fixture while using a suitable punch to remove the roll pin which extracts both the driven gear and the round washer the tang washer and the shim washer from the Distributor shaft. Insert the sensor into the housing after aligning its square-cut hole in the vane wheel. Tighten two new screws for the cmp sensor to 2.2 n.m (19 lb in). Position the Distributor rotor according to mark references at the rotor screw holes along with the rotor locator pin holes. Secure the rotor in place by tightening the two hold-down screws to 1.9 n.m (17 lb in). Begin by placing the shim washer at the bottom of the Distributor shaft and then layer the tang washer and round washer on top. Install the driven gear to index marks that align the rotor segment for v6 engines or v8 engines while adjusting the white paint mark on the Distributor bottom stem to match the pre-drilled gear bottom indent. The driven gear must be correctly installed while checking that the dimple sits at a position where the rotor segment is not at 180 degrees opposition. Place the Distributor drive gear in a v-block or equivalent fixture before hand-driving the roll pin into position using a suitable punch alongside a hammer to secure the driven gear. After installing a new distribution base oil seal, reattach the Distributor before securing the engine cover.
