COOLANT
INSPECTION
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR RESERVOIR
The engine coolant level should be between the ºLOWº and ºFULLº lines.
If low, check for leaks and add engine coolant up to the ºFULLº line, ºwhen the engine is cold.º
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 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.
3. CHECK ENGINE COOLANT FOR LEAKS

ON-VEHICLE CLEANING
CLEAN RADIATOR
Using water or a steam cleaner, remove any mud or dirt from the radiator core.
NOTICE:
If using a high pressure type cleaner, be careful not to deform the fins of the radiator core. (i.e. Main-
tain a distance between the cleaner nozzle and radiator core.)

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.

REASSEMBLY
1. A/T:
INSTALL OIL COOLER TO LOWER TANK
(a) Clean the O-ring contact surface of the lower tank and oil
cooler.
(b) Install new O rings to the oil cooler.
(c) Install the oil cooler with the O-rings to the lower tank.

Torque:
Nut A: 15 N´m (150 kgf´cm, 11 ft´lbf)
Nut B and C: 8.5 N´m (85 kgf´cm, 75 in.´lbf)
2. INSPECT LOCK PLATE
Inspect the lock plate for damage.
HINT:

If the sides of the lock plate groove are deformed, reas-
sembly of the tank will be impossible.

Therefore, first correct any deformation with pliers or like
object. Water leakage will result if the bottom of the lock
plate groove is damaged or dented or dented. There fore,
repair or replace if necessary.
3. INSTALL NEW O-RINGS AND TANKS
(a) After checking that there are no foreign objects in the lock
plate groove, install a new O-ring without twisting it.
HINT:
When cleaning the lock plate groove, lightly rub it with sand pa-
per without scratching it.
(b) Install the tank without damaging the O-ring.
(c) Tap the lock plate with a soft-faced hammer so that there
is no gap between it and the tank.
