2. Clean off the marks and coat them wit
h white paint or chalk, if necessary,
so that they may be seen.
3. Run the engine until it reaches no rmal operating temperature, then shut
off the engine.
4. With the ignition OFF, connect a ta chometer to the distributor, and a
timing light with an inductive pickup lead to the No. 1 spark plug wire.
WARNING - Never pierce a secondary ignition wire in order to connect a timing
light. A pierced wire may lead to engine misfiring and driveability problems.
5. To properly set the ignition timing , the EST must be placed in the bypass
mode. a. On the 2.5L engine, refer to t he emission control label for the
procedure.
If the label is missing or unreadable, c ontact your Chevrolet dealer for a
replacement.
b. On 2.8L and 5.0L ca rbureted engines, disconnect the 4-wire EST
connector at the distributor. (Fault code 42 may be set in ECM memory,
and must be cleared once the procedur e is completed). Proceed to Step
7.
c. On 2.8L, 5.0L and 5.7L fuel inje cted engines, with the engine RUNNING
and all accessories off, use a jumper wire to connect diagnostic terminal
B and ground terminal A of the 12-terminal Assembly Line Diagnostic
Link (ALDL) usually located under t he left side of the instrument panel.
DO NOT disconnect the 4-wir e EST connector at the distributor. Aim the
timing light at the timing mark; the li ne on the balancer or pulley will line
up with the timing mark. Increase engine speed and check for timing
advance. If the timing still advances with engine speed, perform Step 6. If
timing does not advance with engi ne speed, proceed to Step 7.
If timing advances with engine speed, it will be necessary to disconnect the
single-wire Set Timing connector. (Faul t code 42 may be set in ECM memory,
and must be cleared once the procedure is completed).
6. Remove the jumper wire from t he ALDL, and shut off the ignition.
Disconnect the Set Timing connector, usually located under the plastic
cover above the heater unit, in the engi ne compartment. (The wire in this
connector is normally Tan/Black.)
7. With the engine running and all accessories off, aim the light at the timing
mark. The line on the balancer or pulle y will line up with the timing mark.
If a change in timing is necessary, loosen the hold-down clamp bolt at
the base of the distributor . While observing the timing mark, rotate the
distributor slightly unt il the line indicates the correct timing. Use the
timing specification on the emi ssion control label in the engine
compartment. If this label is missi ng or damaged, refer to the Tune-Up
Specifications chart in this Section.

8. Once the timing is set to specific
ation, tighten the distributor hold-down
clamp. Recheck the timing to make su re it did not change while the bolt
was being tightened.
9. Remove the jumper wire from the ALDL connector, if applicable, with the
engine still running. (Usually, if this is performed before the engine is
shut off, no trouble codes will be stored.)
10. Turn the engine OFF, then remove the timing light and tachometer.
Reconnect the number 1 spark plug wire, if disconnected.
11. Attach the 4-wire EST connector at the distributor, or reconnect the Set
Timing connector, if applicable.
12. Check for fault code 42, and clear, if necessary, by disconnecting the
negative battery cable for at least 30 seconds.
To prevent ECM damage, the key must be in the OFF position when
disconnecting or reconnecting battery cables.
1988-90 VEHICLES
When adjusting the timing, refer to the instructions on the emission control
sticker inside the engine compartment. If th e instructions on the label disagree
with the procedure listed below, follo w the instructions on the label.
1. Locate the timing marks on the cran kshaft pulley and the front of the
engine.
2. Clean off the marks and coat them with white paint or chalk, so that they
may be easily seen.
3. Run the engine until it reaches no rmal operating temperature, then shut
off the engine.
4. With the ignition OFF, connect a ta chometer to the distributor, and a
timing light with an inductive pickup lead to the No. 1 spark plug wire.
WARNING - Never pierce a secondary ignition wire in order to connect a timing
light. A pierced wire may lead to engine misfiring and driveability problems.
5. Start the engine. With the engine running and all accessories off, use a
jumper wire to connect diagnostic terminal B and ground terminal A of
the 12-terminal Assembly Line Diagnostic Link (ALDL), located under the
instrument panel.
If jumping the ALDL terminals does not prevent timing advance, the EST
bypass wire will have to be disconnected instead.
6. Aim the timing light at the timing mark. The line on the balancer or pulley
will line up with the timing mark. If a change in timing is necessary,
loosen the hold-down clamp bolt at t he base of the distributor. While
observing the timing mark, rotate the distributor slightly until the line
indicates the correct timing. Use t he timing specification on the emission
control label in the engine compartm ent. If this label is missing or
damaged, refer to the Tune- Up Specifications chart in this Section.

STEERING COLUMN

WARNING - Before attempting any repairs involving the steering wheel or
disassembly of it, ensure that the Supple mental Inflatable Restraint (Air Bag)
system is properly disarmed.
REMOVAL & INSTALLATION
The front of the dash mount ing plates must be loosened whenever the steering
column is to be lowered from the instrument panel.
1. Disconnect the negative battery cable.
2. On 1990-92 vehicles, disable the S upplemental Inflatable Restraint (SIR)
system as follows: a. Turn the steering wheel so th e vehicle's wheels are pointing
straight-ahead.
The wheels of the vehicle must be in the straight-ahead position
and the steering column in the locked position before proceeding
with steering column remo val. Failure to follow this procedure will
cause the SIR coil to become uncentered, resulting in damage to
the coil assembly.
b. Remove the SIR fuse from the fuse block.
c. Remove the left sound insulator by removing the nut from the stud
and gently prying the insulator from the knee bolster.
d. Disconnect the Connector Position Assurance (CPA) and yellow 2-way SIR harness connector at the base of the steering column.
3. Remove the nut and bolt from t he upper intermediate shaft coupling.
Separate the coupling from the lo wer end of the steering column.
4. Remove the steering w heel, if the column is to be replaced or repaired
on the bench.
5. Remove the knee bolster and bracket, if equipped.

6. Remove the bolts attaching the toe plate to the cowl.
7. Disconnect the electrical connectors.
8. Remove the capsule nuts attachi
ng the steering column support bracket
to the instrument panel.
9. Disconnect the park lock cable from the ignition switch inhibitor, if
equipped with automatic transmission.
10. Remove the steering column from the vehicle.
To install:
If a replacement steering column is bein g installed, do not remove the anti-
rotation pin until after the steering co lumn has been connected to the steering
gear. Removing the anti-rotation pin before the steering column is connected to
the steering gear may dam age the SIR coil assembly.
11. Position the steering column in the vehicle.
12. Connect the park lock cable to the ig nition switch inhibitor on vehicles
with automatic transmission.
13. Install the capsule nuts attaching the steering column support bracket to
the instrument panel and tighten to 20 ft. lbs. (27 Nm).
14. Install the nut and bolt to the upper intermediate shaft coupling attaching
the upper intermediate shaft to the steer ing column. Tighten the nut to 44
ft. lbs. (60 Nm).
15. Install the bolts attaching the toe pl ate to the cowl and tighten to 58 inch
lbs. (6.5 Nm).
16. Connect the electrical connectors.
17. Remove the anti-rotation pin if a se rvice replacement steering column is
being installed.
18. Install the knee bolster and bracket, if equipped.
19. Install the sound insulator panel.
If SIR coil has become uncentered by turni ng of the steering wheel without the
column connected to the st eering gear, follow the proper adjustment procedure
for the SIR coil assembly before proceeding.
20. Install the steering wheel.
21. Connect the negative battery cable.
22. Enable the SIR system as follows: a. Connect the yellow 2-way SIR harness connector to the base of
the steering column and CPA clip and install the SIR fuse.
b. Install the left sound insulator.
c. Turn the ignition switch to the RUN position and verify that the
inflatable restraint indicator fl ashes 7-9 times and then turns OFF.
If the indicator does not respond as stated, a problem within the
SIR system is indicated.
