Book Excerpt: 1971-1985 Cadillac Eldorado, Seville, Olds Toronado, Buick Riviera Repair Manual

ENGINE ELECTRICAL SYSTEMS

VACUUM ADVANCE | CHECK AND REPLACEMENT

CHECK (Refer to illustration 9.45)

  1. Refer to Chapter 1, ignition timing check and adjustment, and hook up a timing light as described there.
  2. Start the engine and set the speed at approximately 2,500 rpm.
  3. Observe the timing marks at the front of the engine and remove the vacuum hose from the vacuum advance control unit on the distributor.

    When the hose is removed, the timing mark on the crankshaft pulley should appear to move closer to the stationary mark on the timing tab. When the hose is reconnected, the mark should move away again.

  4. If reconnecting the vacuum hose produces an abrupt increase in advance or none at all, the vacuum advance control unit is probably defective.

    NOTE: Another method to check the vacuum advance assembly is to connect a vacuum pump to the vacuum advance (see illustration) and observe the distributor plate for the proper movement.

  5. REPLACEMENT (Refer to illustration 9.5)

  6. Remove the distributor cap and rotor (see illustration).
  7. Remove the two screws that retain the vacuum advance mechanism to the distributor housing.
  8. Unhook the advance arm from the distributor plate by pushing down on it with a narrow punch, then remove the unit from the distributor.
  9. Installation is the reverse of the removal procedure.

SUSPENSION AND STEERING SYSTEMS
UPPER CONTROL ARM (FRONT) | REMOVAL AND INSTALLATION

REMOVAL (Refer to illustration 8.5)

  1. Loosen the wheel lug nuts, raise the front of the vehicle and support it securely on jackstands. Apply the parking brake. Remove the wheel.
  2. Support the lower control arm with a floor jack. Caution: The jack must remain under the control arm during removal and installation of the balljoint to hold the control arm in position.
  3. Disconnect the upper balljoint from the steering knuckle (see illustration 5.7b).
  4. Remove the upper shock absorber mounting nut and bolt (see Section 3).
  5. Mark the relationship of the cam bolts to the frame bracket. Remove the control arm-to-frame bracket nuts and bolts (see illustration).

Questions & Answers about Cadillac Eldorado, Seville; Olds Toronado; Buick Riviera Repair Manual 1971-1985


does this manual adress the problem of the battery being drained by the alternator or coomputer/ 1985 cad seville?
This manual does have a section for trouble shooting the electrical system, a section on the engine electrical system and also contains many wiring diagrams. It explains such things as the check and replacement of the alternator components, alternator removal and installation, etc. The Computer Command Control (C3) systems are also addressed including trouble codes and how to access them. It does NOT specifically address the battery being drained by the alternator or computer, but perhaps the information could be ascertained utilizing the write-ups and diagnostic codes included. Thanks.

I don't think it talks a lot about the 1972 olds toronado. more on the newer models. I was looking for a Haynes book strickly about the 1972 olds toronado with the 455 olds engine.
