Spark Control Relay: Description and Operation
Fig. 37 - Spark Timing Control System
This system, Fig. 37, used on 1977-78 1.8 liter, 1979-82 2.0 liter and 1981-82 2.3 liter California
with manual transmission models reduces exhaust emissions by delaying vacuum to the distributor
vacuum advance unit during vehicle acceleration.
The system consists of a vacuum delay valve installed in the vacuum line between the carburetor
and distributor on 1.8 liter and 2.0 liter engines except California, or between the water thermo
valve and distributor on 2.0 liter California engines. On 2.3 liter engines, the system consists of a
spark delay valve (manual transmission equipped models) and a distributor solenoid valve installed
in the vacuum line between the intake manifold and distributor. The distributor solenoid valve is
controlled by a timer and water thermo switch (also a distributor water thermo switch on vehicles
with automatic transmission).
The spark delay valve has an internal restrictor to slow air flow in one direction and a check valve
which allows free air flow in the opposite direction.
On 1979-82 California models, distributor vacuum advance is restricted by the water thermo valve
which detects engine coolant temperature. This helps to warm up the catalytic converter.

Figure 17 - Dipstick
To correctly check the engine oil level, the vehicle must be parked on a level surface. Allow a few
minutes after shutting the engine off for oil to drain down before checking. For consistent oil level
readings, insert the dipstick with the loop of the handle as shown in Figure 17.
Figure 18 - Dipstick - Calibration
Figure 19 - Dipstick - Calibration
Dipsticks in Ford vehicles do not incorporate a Full mark. Instead, the dipstick will have marks
indicating a Safe range and an Add range as shown in Figure 18 or 19. When the correct amount
of oil is in the engine, the oil level indication will be in the Safe range or above the Minimum mark,
but not necessarily at the top of the Safe range or at the Maximum mark.
When the indicated oil level is in the Add range put one quart of oil in the engine. Recheck the oil
level to determine if the oil level is now in the Safe range or above the Minimum mark.
Page 45
Add and recheck oil level one quart at a time until the oil level indicator moves into the Safe range
or above the Minimum mark. Do not add additional oil to bring the level to the top of the Safe range
or to the Maximum mark since this may result in overfill and increased oil consumption. If the
accuracy of the engine oil dipstick is in doubt, it may be verified in the following manner:
^ Drain the oil and install a new filter.
^ Put in the specified amount of oil for an oil and filter change. (See owner guide)
^ Start the engine and operate a few minutes.
^ Shut off the engine and allow a few minutes for the oil to drain down.
^ Check the oil level with the dipstick.
^ If the oil level does not indicate in the Safe range or above the Minimum mark, rework or replace
the dipstick.

To prevent repeat servicing on engines suspected of oil leakage at the crankshaft seal, determine if
the leak is actually from the seal or from another source such as the rear pan seal or galley plugs.
The one-piece rear crankshaft seal is released for all passenger car and light truck engines and
has proven to be more reliable than the rope or split lip design formerly used.
Performing the oil leak air pressure check outlined in all Car and Truck Powertrain Shop Manuals,
Section 21- 01 will accurately identify the location of the leak and can verify correction after
servicing before the transmission is reinstalled.

HEATER CORE - LEAK - DIAGNOSTIC TIPS
FORD ALL
LINCOLN-MERCURY ALL
LIGHT TRUCK ALL
Good heater cores are being returned through the parts return system coded as leaking.
Complaints of leaking may be caused by an inadequate seal between the heater hose and the
heater core tubes allowing coolant to follow the tube to the heater core, leak into the passenger
compartment and appear as a leaking heater core.
When diagnosing a suspect heater core leak, inspect the hose to heater core tube attachment to
assure the connection is not leaking. If a leaking connection is found, correct the leak. If the
connection appears not to be leaking, leak test the heater core before removing it from the vehicle
using the following procedure:
HEATER CORE LEAK TEST
Pressure Test 1.
Drain the coolant from the cooling system.
2. Disconnect the heater hoses from the heater core tubes.
Page 82
3. Install a short piece of heater hose (approximately 4 inches long) on each heater core tube.
Figure 1
4. Fill the heater core and hoses with water and install plug BT-7422-B and adapter BT-7422-A
from Rotunda model 021-00012 or equivalent in the hose ends (Figure 1). Secure the hoses, plug
and adapter with hose clamps.

5. Attach the pump and gauge assembly Rotunda model 021-00012 or equivalent to the adapter
(Figure 2). Close the bleed valve at the base of the gauge and pump 30 psi of air pressure into the
heater core (Figure 3).
6. Observe the pressure gauge for a minimum of three minutes. The pressure should not drop.
7. If the pressure does not drop, no leaks are indicated.
8. If the pressure drops, check the hose connections to the core tubes for leaks. If the hoses do not
leak, remove the heater core from the vehicle and perform the bench test.
Bench Test 1.
Drain all coolant from the heater core.
Figure 4 - HEATER CORE BENCH TEST
2. Connect the 4-inch test hoses with plug and adapter to the core tubes. Then connect the air
pump and gauge assembly to the adapter (Figure 4).
3. Apply 30 psi of air pressure to the heater core with Rotunda model 021-00012 or equivalent, and
submerge the core in water.
4. If a leak is observed, service or replace the heater core as necessary.

Catalytic Converter: Description and Operation
Some 1976-82 vehicles use a catalytic converter to reduce hydrocarbon and carbon monoxide
exhaust emission levels. These vehicles are also equipped with a catalyst warning system. This
system is comprised of a thermo sensor on the catalytic converter, monitoring converter
temperature, and a warning lamp on the instrument panel which illuminates when the thermo
sensor detects converter temperatures over 1742°F.

Warning System Test
1. Turn ignition switch to "On" position. The warning lamp should illuminate, indicating that the bulb
and electrical wiring are satisfactory. If lamp
does not light, check bulb.
2. Start engine and if the system is satisfactory, the warning lamp should go out. If not, stop engine
and tilt the seatback forward.
4. With an ohmmeter, check the circuit on the thermo sensor side of the wiring for continuity, Fig.
31. Replace the thermo sensor if the reading
indicates no continuity.

EXHAUST - MUFFLER - POWER LOW - UNNECESSARY MUFFLER REPLACEMENT
LIGHT TRUCKS 1982 AND LATER LIGHT TRUCKS
Mufflers are being replaced on leaded fuel vehicles in an effort to resolve concerns of "lack of
power" or poor performance", apparently in the belief that a plugged muffler is the cause. Although
plugging with lead deposits was possible on certain models prior to the 1982 Model Year, muffler
modifications incorporated on 1982 and later models make this an unlikely cause of the concern.
Thus, replacing mufflers on the newer model vehicles normally will not satisfy the customer. Prior
to replacing any muffler believed to be restricted, a vacuum check as described in Section 26-01 of
the Light Truck Shop Manual should be performed.

Spark Control Relay: Description and Operation
Fig. 37 - Spark Timing Control System
This system, Fig. 37, used on 1977-78 1.8 liter, 1979-82 2.0 liter and 1981-82 2.3 liter California
with manual transmission models reduces exhaust emissions by delaying vacuum to the distributor
vacuum advance unit during vehicle acceleration.
The system consists of a vacuum delay valve installed in the vacuum line between the carburetor
and distributor on 1.8 liter and 2.0 liter engines except California, or between the water thermo
valve and distributor on 2.0 liter California engines. On 2.3 liter engines, the system consists of a
spark delay valve (manual transmission equipped models) and a distributor solenoid valve installed
in the vacuum line between the intake manifold and distributor. The distributor solenoid valve is
controlled by a timer and water thermo switch (also a distributor water thermo switch on vehicles
with automatic transmission).
The spark delay valve has an internal restrictor to slow air flow in one direction and a check valve
which allows free air flow in the opposite direction.
On 1979-82 California models, distributor vacuum advance is restricted by the water thermo valve
which detects engine coolant temperature. This helps to warm up the catalytic converter.
