REPLACEMENT
1. DRAIN ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
(b) Loosen the radiator drain plug (on the right side of the ra-
diator lower tank) and engine drain plug (on the left front
of the cylinder block), and drain the coolant.
(c) Close the drain plugs.
Torque: 25 N´m (250 kgf´cm, 18 ft´lbf)
2. FILL ENGINE COOLANT
(a) Slowly fill the system with coolant.

Use a good brand of ethylene-glycol base coolant
and mix it according to the manufacturer's direc-
tions.

Using coolant which includes more than 50 % ethyl-
ene-glycol (but not more than 70 %) is recom-
mended.
NOTICE:

Do not use an alcohol type coolant.

The coolant should be mixed with demineralized wa-
ter or distilled water.
Capacity (w/ Heater):
M/T4.9 liters (5.2 US qts, 4.3 lmp. qts)
A/T5.3 liters (5.6 US qts, 4.7 lmp. qts)
(b) Install the radiator cap.
(c) Start the engine, and bleed the cooling system.
(d) Refill the radiator reservoir with coolant until it reaches the
ºFULLº line.

ON-VEHICLE INSPECTION
1. REMOVE RADIATOR CAP
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
2. INSPECT RADIATOR CAP
NOTICE:

If the radiator cap has contaminations, always rinse
it with water.

Before using a radiator cap tester, wet the relief valve
and pressure valve with engine coolant or water.

When performing steps (a) and (b) below, keep the
tester at an angle of over 30° above the horizontal.
(a) Using a radiator cap tester, slowly pump the tester and
check that air is coming from the vacuum valve.
Pump speed: 1 push/3 seconds or more
NOTICE:
Push the pump at a constant speed.
If air is not coming from the vacuum valve, replace the radiator
cap.
(b) Pump the tester and measure the relief valve opening
pressure.
Pump speed: 1 push within 1 second
NOTICE:
This pump speed is for the first pump only (in order to close
the vacuum valve). After this, the pump speed can be re-
duced.
Standard opening pressure:
74 - 103 kPa (0.75 - 1.05 kgf/cm
2, 10.7 - 14.9 psi)
HINT:
Use the tester's maximum reading as the opening pressure.
If the opening pressure is less than minimum, replace the radia-
tor cap.
3. INSPECT COOLING SYSTEM FOR LEAKS
(a) Fill the radiator with coolant and attach a radiator cap tes-
ter.
(b) Warm up the engine.
(c) Pump it to 118 kPa (1.2 kgf/cm
2, 17.1 psi), and check that
the pressure does not drop.
If the pressure drops, check the hoses, radiator or water pump
for leaks. If no external leaks are found, check the heater core,
cylinder block and head.
4. REINSTALL RADIATOR CAP

- CHARGINGCHARGING SYSTEM
1996 TERCEL (RM440U)

Connect the positive (+) tester probe of the amme-
ter to terminal B of the generator.

Connect the positive (+) tester probe of the voltme-
ter to terminal B of the generator.

Ground the negative (-) tester probe of the voltme-
ter.
(b) Check the charging circuit as follows:
With the engine running from idling to 2,000 rpm, check
the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage:
at 25°C (77°F)13.9 - 15.1 V
at 115°C (239°F)13.5 - 14.3 V
If the voltmeter reading is greater than standard voltage, re-
place the voltage regulator.
If the voltmeter reading is less than standard voltage, check the
voltage regulator and generator as follows:

With terminal F grounded, start the engine and
check the voltmeter reading of terminal B.

If the voltmeter reading is greater than standard
voltage, replace the voltage regulator.

If the voltmeter reading is less than standard volt-
age, check the generator.
7. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high
beam headlights and place the heater blower switch at
ºHIº.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
If the ammeter reading is less than the standard amperage, re-
pair the generator.
HINT:
If the battery is fully charged, the indication will sometimes be
less than standard amperage.
