COOLANT
INSPECTION
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR RESERVOIR
The engine coolant level should be between the ºLOWº and ºFULLº lines, when the engine is cold.
If low, check for leaks and add engine coolant up to the ºFULLº line.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator
are still hot, as fluid and steam can be blown out under pressure.
(b) There should not be any excessive deposits of rust or scale around the radiator cap or radiator filler
hole, and the coolant should be free from oil.
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap.

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 2 drain plugs (for the engine and radiator),
and drain the coolant.
HINT:
To prevent the coolant from spraying over the cylinder block,
connect the rubber hose (inside diameter 6 - 8 mm) in the mar-
ket to the union pipe under.
(c) Close the drain plugs.
Torque:
Engine drain plug
29 N´m (300 kgf´cm, 22 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.

(b) Install the radiator cap.
(c) Start the engine, and bleed the cooling system.
(d) Refill the 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.

When performing steps (a) and (b) below, keep the ra-
diator pump tester at an angle of over 30° above the
horizontal.
(a) Before using a radiator cap tester, wet the relief valve and
pressure valve with engine coolant or water.
(b) 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.
(c) 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:
93 - 123 kPa (0.95 - 1.25 kgf/cm
2, 13.5 - 17.8 psi)
Minimum opening pressure:
78 kPa (0.8 kgf/cm
2, 11.4 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 147 kPa (1.5 kgf/cm
2, 21.3 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 cylinder head.
4. REINSTALL RADIATOR CAP
