4. Spray a commercial solvent onto the sensor threads and allow it to soak
in for at least five minutes.
5. Carefully remove the sensor wit h a special oxygen sensor socket.
To install: 6. First coat the new sensor's th reads with GM anti-seize compound No.
5613695 or the equivalent. This is not a conventional anti-seize paste.
The use of a regular compound may el ectrically insulate the sensor,
rendering it inoperative. Y ou must coat the threads with an electrically
conductive anti-seize compound. Installati on torque is 30 ft. lbs. (41 Nm).
Do not overtighten.
7. Reconnect the electric al wiring. Be careful not to damage the electrical
pigtail. Check the sensor boot fo r proper fit and installation.
8. Reconnect the negative battery cable.
COOLANT TEMPERATURE SENSOR
OPERATION
Most engine functions are affected by the coolant temperature. Determining
whether the engine is hot or cold is largely dependent on the temperature of the
coolant. An accurate temperature signal to the ECM is supplied by the coolant
temperature sensor. The coolant temperatur e sensor is a thermistor mounted in
the engine coolant stream. A thermistor is an electrical device that varies its
resistance in relation to changes in temperature. Low coolant temperature
produces a high resistance and high coolant temperature produces low
resistance. The ECM supplies a signal of 5 volts to the coolant temperature
sensor through a resistor in the ECM and measures the voltage. The voltage
will be high when the engine is cold and low when the engine is hot.
REMOVAL & INSTALLATION
1. Disconnect the negative battery cable.
2. Drain the cooling system to an appropr iate and clean container for reuse.
3. Disconnect the electrical wiring fr om the coolant temperature sensor.
4. Remove the coolant temperature sensor.
To install: 5. Install the coolant temperature sensor.

as much voltage to fire the plug at hi
gh speeds than at idle. The improved
air/fuel ratio control of modern fuel injection combin ed with the higher voltage
output of modern ignition systems will often allow an engine to run significantly
longer on a set of standard spark plugs, but keep in mind that efficiency will
drop as the gap widens (along wit h fuel economy and power).
When you're removing spark plugs, work on one at a time. Don't start by
removing the plug wires all at once, because, unless you number them, they
may become mixed up. Take a minute before you begin and number the wires
with tape.
1. Disconnect the negative battery cabl e, and if the vehicle has been run
recently, allow the engine to thoroughly cool.
2. Carefully twist the spark plug wire boot to loosen it, then pull upward and
remove the boot from the plug. Be su re to pull on the boot and not on the
wire, otherwise the connector locat ed inside the boot may become
separated.
3. Using compressed air, blow any water or debris from the spark plug well
to assure that no harmful contam inants are allowed to enter the
combustion chamber when the spark plug is removed. If compressed air
is not available, use a rag or a brush to clean the area.
Remove the spark plugs when the engine is cold, if possible, to prevent damage
to the threads. If removal of the plugs is difficult, apply a few drops of
penetrating oil or silicone spray to t he area around the base of the plug, and
allow it a few minutes to work.
4. Using a spark plug socket that is equipped with a rubber insert to
properly hold the plug, turn the spar k plug counterclockwise to loosen
and remove the spark pl ug from the bore.
WARNING - Be sure not to use a flexible extension on the socket. Use of a
flexible extension may allow a shear fo rce to be applied to the plug. A shear
force could break the plug off in the cylinder head, leading to costly a\
nd
frustrating repairs.
To install:
5. Inspect the spark plug boot for t ears or damage. If a damaged boot is
found, the spark plug wire must be replaced.
6. Using a wire feeler gauge, check and adjust the spark plug gap. When
using a gauge, the proper size shoul d pass between the electrodes with
a slight drag. The next larger size should not be able to pass while the\

next smaller size should pass freely.
7. Carefully thread the plug into the bor e by hand. If resistance is felt before
the plug is almost completely th readed, back the plug out and begin
threading again. In small, hard to r each areas, an old spark plug wire and
boot could be used as a th reading tool. The boot will hold the plug while
you twist the end of the wire and t he wire is supple enough to twist
before it would allow t he plug to crossthread.

WARNING
- Do not use the spark plug socke t to thread the plugs. Always
carefully thread the plug by hand or us ing an old plug wire to prevent the
possibility of crossthreading and damaging the cylinder head bore.
8. Carefully tighten the spark plug. If the plug you are installing is equipped
with a crush washer, seat the plug, then tighten about
1/4 turn to crush
the washer. If you are installing a t apered seat plug, tighten the plug to
specifications provided by the vehicle or plug manufacturer.
9. Apply a small amount of silicone di electric compound to the end of the
spark plug lead or inside the spark pl ug boot to prevent sticking, then
install the boot to the spark plug and pus h until it clicks into place. The
click may be felt or hear d, then gently pull back on the boot to assure
proper contact.
INSPECTION & GAPPING
Check the plugs for deposits and wear. If they are not going to be replaced,
clean the plugs thoroughly. Remember t hat any kind of deposit will decrease
the efficiency of the plug. Plugs can be cleaned on a spark plug cleaning
machine, which can sometimes be found in service stations, or you can do an
acceptable job of cleaning with a stiff br ush. If the plugs are cleaned, the
electrodes must be filed flat. Use an igni tion points file, not an emery board or
the like, which will leave deposits. The electrodes must be filed perfectly flat
with sharp edges; rounded edges reduce the s park plug voltage by as much as
50%.
Check spark plug gap before installati on. The ground electrode (the L-shaped
one connected to the body of the plug) mu st be parallel to the center electrode
and the specified size wire gauge (please refer to the Tune-Up Specifications
chart for details) must pass between t he electrodes with a slight drag.
NEVER adjust the gap on a used platinum type spark plug .
Always check the gap on new plugs as they are not always set correctly a\
t the
factory. Do not use a flat feeler g auge when measuring the gap on a used plug,
because the reading may be inaccurate. A round-wire type gapping tool is the
best way to check the gap. The co rrect gauge should pass through the
electrode gap with a slight drag. If you're in doubt, try one size smaller and one
larger. The smaller gauge should go through easily, while the larger one\

shouldn't go through at all. Wire gapping tools usually have a bending tool
attached. Use that to adjust the side electrode until the proper distance is
obtained. Absolutely never attempt to bend the center electrode. Also, be
careful not to bend the side electrode too fa r or too often as it may weaken and
break off within the engine, requiring remova l of the cylinder head to retrieve it.

In the HEI system, as in other electr
onic ignition systems, the breaker points
have been replaced wit h an electronic switch - a tr ansistor - which is located
within the ignition module. This switching transistor pe rforms the same function
the points did in a conventi onal ignition system; it simply turns the coil's primary
current on and off at the correct time. Essentially, electronic and conventional
ignition systems operate on t he same principle.
The module which houses the switching transistor is controlled (turned on and
off) by a magnetically gener ated impulse induced in the pickup coil. When the
teeth of the rotating timer align with t he teeth of the pole piece, the induced
voltage in the pickup coil signals the elec tronic module to open the coil primary
circuit. The primary current then decreases, and a high voltage is induced in the
ignition coil secondary windings, which is then directed through the rotor and
high voltage leads (spark plug wires) to fire the spark plugs.
In essence, the pickup coil module system simply replaces the conventional
breaker points and condenser. The condenser found within the distributor is for
radio suppression purposes only and has nothing to do with the ignition
process. The ignition module automatically controls the dwell period, increasing
it with increasing en gine speed. Since dwell is co ntrolled in this manner, it
cannot be adjusted. The module itse lf is non-adjustable/non-repairable and
must be replaced if found defective.
SYSTEM PRECAUTIONS
Before proceeding with troubleshooting, ta ke note of the following precautions:
TIMING LIGHT USE
Care should be exercised when connec ting a timing light or other pick-up
equipment. Do not force anything between the boots and wiring, or through the
silicone jacket. Connections should be made in parallel using an adapter.
Inductive pickup timing lights are the bes t kind to use with the ignition systems
covered by this information.
SPARK PLUG WIRES
The plug wires used with these systems are of a different construction than
conventional wires. When replacing them, make sure you get the correct wires,
since conventional wires will not carry the voltage. Also, handle the wires
carefully to avoid cracking or splitti ng them, and NEVER pierce the wires.
TACHOMETER USE
Not all tachometers will operate or indi cate correctly when used on an HEI or
C
3I system. While some tachometers ma y give a reading, this does not
necessarily mean the reading is correct. In addition, some tachometers hook up
differently from others. If you cannot fi gure out whether or not your tachometer
will work on your car, check with the tachometer manufacturer.

3. If no defects have been found at this
time, and you still have a problem,
then the module will have to be che cked. If you do not have access to a
module tester, the only possible alter native is a substitution test. If the
module fails the substitution test, replace it.
COMPONENT REPLACEMENT

CAUTION - When handling secondar y spark plug leads with the engine running
or starting, insulated pliers must be used and care exercised to prevent a
possible electrical shock.
