How do you replace the distributor cap on a 1991 Cavalier?

Answer 1

It depends on what engine you have. Some don't have distributers. GoodluckJoe

For the 1.8L & 2.0 L OHV Engines (For diagrams e-mail me: LanceRViolator@aol.com) <From a Chilton's> ON Chevrolet V6 models the distributor body is involved in the engine lubrication system. The lubrication circuit to the right bank valve train can be interrupted by misalignment of the distributor body. (Know your firing order to have correct position)

The '87-92 Chevy built 4 cyl 2.0: & V6 2.8L engines do not have a distributor. (They are DIS)

1. Disconnect the negative battery cable. 2. Tag and disconnect all wires leading from the distributor cap. 3. Remove the air cleaner housing as previously detailed. 4. Remove the distributor cap. 5. Disconnect the AIR pipe-to-exhaust manifold hose at the air management valve. 6. Unscrew the rear engine lift bracket bolt an nut, lift it off the stud and then position the entire assembly out of the way to facilitate better access to the distributor. 7. Mark the position of the distributor, relative to the engine block and then scribe a mark on the distributor body indication the initial position of the rotor. 8. Remove the holddown nut and clamp fro the base of the distributor. Remove the distributor from the engine. The drive gear on the distributor shaft is helical and the shaft will rotate slightly as the distributor is removed. Note and mark the posistion of the rotor at this secod position. Do not crank the engine while the distributor is removed. 9. To install the distributor, rotate the shaft until the rotor aligns with the second mark you made (when the shaft stoped moving). Lubricate the drive gear with clean engine oil and install the distributor into the engine. As the distributor is installed the rotor should move to the first mark that you made. This will ensure proper timing. If the marks do not align properly, remove the didtributor and try again. 10. Install the clamp and holddown nut.

--> You may wish to use a magnet attached to a extention bar to position the clamp on the stud.

11. Installation o fthe remaining components is in the reverse order of removal. Check the ignition timing.

1.8L and 2.0L OHC Engines ( For Diagram e-mail me)

1. Disconnect the battery ground 2. Mark the spark plug wires and remove the wires & coil. 3. Matchmark the position of the rotor, distributor body and cylinder head. 4. Disconnect the wiring from the distributor. 5. Remove the two distributor holddown nuts. 6. Remove the distributor. 7. Installation is the reverse of removal. Torque the holddown nuts to 13 ft. lbs.
