Circuit Breaker - a circuit breaker is basically a self-repairing fuse. It will
open the circuit in the same fashio n as a fuse, but when the surge
subsides, the circuit breaker can be reset and does not need
replacement.
• Fusible Link - a fusible link (fuse link or main link) is a short length of
special, high temperatur e insulated wire that acts as a fuse. When an
excessive electrical current passes th rough a fusible link, the thin gauge
wire inside the link melt s, creating an intentional open to protect the
circuit. To repair the circuit, the link must be replaced. Some newer type
fusible links are housed in plug-in modules, which are simply replaced
like a fuse, while older type fusible lin ks must be cut and spliced if they
melt. Since this link is very early in the electrical path, it's the first place to
look if nothing on the vehicle works, yet the battery seems to be charged
and is properly connected.
CAUTION - Always replace fuses, circ uit breakers and fusible links with
identically rated component s. Under no circumstances should a component of
higher or lower amperage rating be substituted.
SWITCHES & RELAYS
Switches are used in electrical circuits to control the passage of current. The
most common use is to open and close circuits between the battery and the
various electric devices in the system. Switches are rated according to the
amount of amperage they c an handle. If a sufficient amperage rated switch is
not used in a circuit, the switch could overload and cause damage.

flashers and fusible links

WINDSHIELD WIPER MOTOR
REMOVAL & INSTALLATION 1. Disconnect the negative batte ry cable at the battery.
2. Remove the screen or grille that covers the cowl area.
3. Working under the hood, disconnec t the motor wiring. Then, reach
through the cowl opening and loosen, but do not remove, the nuts which
attach the transmission drive link to the motor crank arm. Then,
disconnect the drive link from the crank arm.
4. Remove the three motor attach ing screws, and remove the motor,
guiding the crank arm through the hole.
To install: 5. Position the motor, guiding the crank arm thr ough the hole, and install
the 3 motor attaching screws.
6. Connect the drive link to the cran k arm and connect the motor wiring.
The motor must be in the park position before assemb ling the crank arm to the
transmission drive link(s).
7. Install the screen or grille that covers the cowl area.
8. Connect the negative battery cable at the battery.

THERMOSTATIC AIR CLEANER (THERMAC)
OPERATION
This system is designed to warm the air entering the carburetor when
underhood temperatures are low, and to ma intain a controlled air temperature
into the carburetor or throttle body at all times. By allowing preheated air to
enter, the amount of time t he choke is on is reduced, resulting in better fuel
economy and lower emissions. Engine warm-up time is also reduced.
The THERMAC system is composed of th e air cleaner body, a filter, sensor
unit, vacuum diaphragm, damper door, a ssociated hoses and connections. Heat
radiating from the exhaust manifold is tr apped by a heat stove and is ducted to
the air cleaner to supply heated air to t he carburetor or throttle body. A movable
door in the air cleaner case snorkel allows air to be drawn in from the heat stove
(cold operation). The door position is co ntrolled by the vacuum motor, which
receives intake manifold vacuum as modulated by the temperature sensor.
A vacuum door which remain s open can cause carburetor icing or poor cold
driveability. A door which remains clos ed during normal engine operating
temperatures can cause sluggishne ss, engine knocking and overheating.

MINIMUM IDLE SPEED
The minimum idle speed should onl
y be adjusted under two conditions:
If the throttle body has been replaced.
After every other possible cause for the in correct idle speed has been explored.
There are many possible causes for incorre ct idle speed, most of which require
a high level of diagnostic skill as well as expensive testing equipment. Check
the vehicle for vacuum leaks, incorrect valve or ignition timing, deposit
accumulation in the throttle bore or valve, sticking throttle linkage or bent throttle
valves. If the vehicle will still not idle pr operly after checking these areas, it
should be diagnosed by a professional.
1. Pierce the idle stop screw with an awl. Apply leverage to remove it.
2. Make sure the IAC valve is connect ed. Short the A and B terminals of the
ALDL connector together with a length of wire.
3. Turn the ignition to the ON positi on, but do not start the engine. Wait at
least 30 seconds before proceeding.
4. With the ignition ON, disconnect the IAC valve connector.
5. Separate the set-timing connector. Th is eliminates the possibility of
changes in engine speed due to variations of engine timing.
6. Start the engine and remove t he wire shorting the A and B terminals
together. It may be necessary to hold the throttle open slightly to prevent
the engine from stalling.
7. Allow the engine to reach no rmal operating temperature.
8. Adjust the idle speed to the following: a. 2.8L Engines - 450-550 rp m A/T or 550-650 rpm M/T
b. 3.1L Engines - Refer to the underhood emissions sticker
c. 5.0L and 5.7L TPI engines - 400-450 rpm.
If these figures differ from t hose on the underhood emissions
sticker, always follow the specifications on the emissions sticker.
9. Turn the ignition OFF and connect the IAC valve harness. On models up
to 1989, adjust the Throttle Position Sensor.
THROTTLE POSITION SENSOR (TPS) 1. Install three jumper wires betw een the TPS and the harness connector.
2. Use a digital voltmeter connected to terminals A and B of the TPS.
3. Turn the ignition switch ON , but do not start the engine.
4. Loosen the TPS attaching screws and adj ust the sensor to the following:
a. 2.8L Engines - 0.50-0.60 volts
b. 5.0L and 5.7L TPI Engines - 0.47-0.61 volts
5. Tighten the attaching screws, then check that the reading has not been
disturbed.
6. With the ignition OFF, remove the jumper wires. Reconnect the TPS
harness.

Fig. 4: Add clean oil to the engine to ac hieve the correct level, indicated on
dipstick. Do not overfill
Your engine oil should be checked at regular intervals (such as every fuel stop).
Check the engine oil as follows:
1. Make sure the car is parked on level ground.
2. When checking the oil le vel it is best for the engine to be at normal
operating temperature, although checking the oil immediately after
stopping will lead to a false reading. Wa it a few minutes after turning off
the engine to allow the oil to drain back into the crankcase.
3. Open the hood and locate the dipsti ck which should be on either the
passenger's side for the V8 engine or driver's side for the L4 and V6
engines. Pull the dipstick fr om its tube, wipe it clean and then reinsert it.
4. Pull the dipstick out agai n and, holding it horizontally, read the oil level.
The oil should be between the FULL and ADD marks on the dipstick. If
the oil is below the ADD mark, add oil of the prop er viscosity through the
capped opening in the top of the cylinder head cover.
5. Replace the dipstick and check the o il level again after adding any oil. Be
careful not to overfill the crankcase. Approximately 1 quart (0.9L) of oil
will raise the level from the ADD mark to the FULL mark. Excess oil will
generally be consumed at an accelerated rate.
