How do you replace the distributor cap on a 1991 Cavalier?
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.
follow the spark plug wires to the cap, find the two screws holding the cap down to the distributor,with a screwdriver press down and turn the screw 180 degree's and then the other one, pull the cap off, put the new cap on, make sure the cap is down where it belongs, push the screws down and rotate them back 180 degree's, now replace each wire one at a time don't get them mixed up…
# Unplug the distributor connector from wiring harness connector # Loosen the distributor cap retaining screws # Label and disconnect the spark plug cables from the distributor cap # Lift the cap off of the distributor # Note in which direction the distributor spark pick-up is pointing then pull the rotor off of the distributor shaft
If your engine has a distributor cap then I would replace the cap and rotor with a FACTORY OEM. Cap and that should fix your problem. Now if you have the new stayle engine that don't have a distributor cap then I would replace the coil that is mounted on the top of the valve cover for the #6 cylinder.
Unplug the wires going into the distributor cap, be sure you know which wire goes to which terminal or your car will not start if they are wrong. Remove the 3 bolts that hold the plastic cap to the metal distributor. Put the new cap back on, replace the bolts, and plug the wires into the appropriate terminal.
The 4 cylinder has the PCV located under a threaded cap that is screwed into the valve cover on the back side. You will need to remove the vacc. hose from the cap and then unscrew the cap and remove the PCV from the hole that is opened up and replace the valve and install the cap and hose. It will be oil covered and that is normal.
How would you change the spark plug wires and plugs and the coil and how do you open the distributor cap on a 1993 Taurus?
My Eagle Summit sedan 1.8L Auto will not start when it is wet when i turn it over i see sparks coming out of the distributor cap should I replace the cap or the whole distributor thanks?
Replace the distributor cap it is either cracked or worn out. While you are at it replace the plug wires since they are probably not in much better shape. Be sure and lube the inside of the plug boots with dielectic grease on both ends of the wires. your local parts store can supply you with everything mentioned.
