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.

INSTALLATION
1. INSTALL WATER PUMP
(a) Remove any old packing (FIPG) material and be careful
not to drop any oil on the contact surfaces of the water
pump and cylinder block.
Using a razor blade and gasket scraper, remove all
the old packing (FIPG) material from the contact
surfaces and sealing groove.
Thoroughly clean all components to remove all the
loose material.
Using a non-residue solvent, clean both sealing
surfaces.
(b) Apply seal packing to the water pump groove.
Seal packing:
Part No. 08826-00100, THREE BOND 1282B or
equivalent
Install a nozzle that has been cut to a 2 - 3 mm (0.08
- 0.12 in.) opening.
HINT:
Avoid applying an excessive amount to the surface.
Parts must be assembled within 5 minutes of ap-
plication. Otherwise the material must be removed
and reapplied.
Immediately remove nozzle from the tube and rein-
stall cap.
Do not pour in any coolant until at least 2 hours after
installation is completed.
(c) Install the water pump with the bolt and 2 nuts.
Torque: 17.5 N´m (175 kgf´cm, 14 ft´lbf)
2. INSTALL OIL DIPSTICK GUIDE AND GENERATOR AD-
JUSTING BAR
(a) Install a new O-ring to the dipstick guide.
(b) Apply soapy water to the O-ring.
(c) Push in the dipstick guide, and install it with the mounting
bolt of the generator adjusting bar and dipstick guide
clamp.
Torque: 18.5 N´m (185 kgf´cm, 14 ft´lbf)
(d) Install the oil dipstick.

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
