To install:
9. Install the new line or hose, starti
ng with the end farthest from the master
cylinder. Connect the other end, then confirm that both fittings are correctly
threaded and turn smoothly using finger pressure. Make sure the new line
will not rub against any ot her part. Brake lines must be at least 1/2 in.
(13mm) from the steering column and other moving parts. Any protective
shielding or insulators must be rein stalled in the original location.
WARNING - Make sure the hose is NO T kinked or touching any part of the
frame or suspension after installation. These conditions may cause the hose to
fail prematurely.
10. Using two wrenches as bef ore, tighten each fitting.
11. Install any retaining clips or brackets on the lines.
12. If removed, install the wheel and tire assemblies, then carefully lower the
vehicle to the ground.
13. Refill the brake master cylinder re servoir with clean, fresh brake fluid,
meeting DOT 3 specifications. Pr operly bleed the brake system.
14. Connect the negative battery cable.

ARMING SENSOR
The arming sensor is a protective switch
located in the power feed side of the
deployment loop. It is calibrated to clos e at low level velocity changes (lower
than the discriminating sens ors). This assures that the inflator module is
connected directly to the 36 volt output of the DERM or battery voltage feed
when either of the discrim inating sensors close.
DISCRIMINATING SENSORS
The discriminating sensors are wired in parallel on the ground side of the
deployment loop. These sensors are calib rated to close with velocity changes
which are severe enough to warrant deployment.
SIR COIL ASSEMBLY
The SIR coil assembly consists of two cu rrent carrying coils. They are attached
to the steering column and allow rotation of the steering wheel while maintaining
continuous contact of the deployment loop to the inflator module.
INFLATOR MODULES
Each inflator module consists of an inflat able bag and an inflator (a canister of
gas generating material with an initiati ng device). When the vehicle is in a
frontal crash of sufficient force, current flows through the deployment loops.
Current flowing through the initiator ignite s the material in the inflator module.
The gas produced from this reaction rapidly inflates the air bag.

Fig. 4: Then remove the rocker arm pivot
Be sure to keep all the components in t he exact order of removal so they may
be installed in there original location; adjust the valve lash after replacing the
rocker arms. Coat the replacement ro cker arm and ball with engine oil before
installation.
Rocker arms studs that have damaged thr eads or are loose in the cylinder
heads may be replaced by reaming the bore and installing oversize studs.
Oversizes available are 0.003 in. (0. 076mm) and 0.013 in (0.33mm). The bore
may also be tapped and screw-in studs installed. Several aftermarket
companies produce complete rocker arm st ud kits with installation tools.
The 2.5L engine use bolts instead of studs, 2.8L and 3.1L engines use threaded
studs, the 3.4L, 5.0L and 5.7L engines use press fit studs.
EXCEPT 2.5L ENGINES 1. Disconnect the negative (-) battery cable.
2. Remove the rocker arm cover as outlined in this section
3. Remove the rocker arm nuts, balls and rocker arms. Place components
in a rack so they can be reinstalled in the same location.
To install: 4. Coat the bearings surf aces with a thin coating of Molykote® or its
equivalent.
5. Install the pushrods and make sure the rod is in the lifter seat.

6. Install the rocker arm, balls and
nut. Tighten the nut until all lash is
eliminated.
7. The engine must be on the No. 1 fi ring position before proceeding. This
may be determined by placing your fi ngers on the No. 1 rocker arms as
the mark crankshaft damper is rotat ed towards the "0" on the timing tab.
If the arms did not move, it is in the No. 1 firing position. If they did move,
turn the crankshaft one full revoluti on to reach the No. 1 position.
Remember, the mark on the crankshaft balancer must be aligned with
the "0" on the timing tab.
8. Adjust the valves as follows:
V6 ENGINES
With the engine on the number 1 firing pos ition, exhaust valves 1, 2 and 3 and
intake valves 1, 5 and 6
may be adjusted. Back out t he adjusting nut until lash is felt at the pushrod.
Tighten the adjusting nut unt il all lash is removed, then tighten the nut an
additional 1
1/2 turns to center the lifter plun ger. Turn the engine one revolution
until the "0" timing mark is once again al igned. Exhaust valves 4, 5 and 6 and
intake valves 2, 3 and 4 may be adjusted.
V8 ENGINES
With the engine on the number 1 firing posit ion, exhaust valves 1, 3, 4 and 8,
intake valves 1, 2, 5 and 7 may be adj usted. Back out the adjusting nut until
lash is felt at the pushrod. Tighten the adjusting nut until all lash is removed,
then tighten an additional 1 turn to center the lifter plunger. Turn the engine one
revolution until the 0 timing mark is once again aligned. Exhaust valves 2, 5, 6
and 7, intake valves 3, 4, 6 and 8 may be adjusted.
