2. CHECK ENGINE COOLANT QUALITY
There should not be any excessive deposits of rust or
scales around the radiator cap or radiator filler hole,
and the engine coolant should be free from oil.
If excessively dirty, replace the engine coolant.
3. REPLACE ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION: To avoid the danger of being burned, do not
remove It while the engine and radiator are still hot, as
fluid and steam can be blown out under pressure.
(b) Drain the engine coolant from the radiator drain cock
and engine drain plug. (Engine drain plug at the right
rear of cylinder block.)
(c) Close the drain cock and plug.
Torque (Engine drain plug):
13 N±m (130 kgf±cm, 9 ft±lbf)
(d) Slowly fill the system with coolant.
Use a good brand of ethylene±glycol base
coolant and mix it according to the
manufacturer 's directions.
Using engine coolant which includes more than
5096 ethylene±glycol (but not more than 7096) is
recommended.
NOTICE:
wDo not use a alcohol type coolant.
wThe engine coolant should be mixed with demineral±
ized water or distilled water.
Capacity (w/ Heater):
8.3 liters (6.7 US qts, 5.5 Imp.qts)
(a) Reinstall the radiator cap.
(f) Warm up the engine and check for leaks.
(g) Recheck the engine coolant level and refill as neces±
sary.
COOLANT CHECK AND
REPLACEMENT
1. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
TANK
The engine coolant level should be between the
ºLOWº and ªFULLº lines.
If low, check for leaks and add engine coolant up to
the ªFULLº line.

THERMOSTAT REMOVAL
HINT: Removal of the thermostat would have an ad±
verse effect, causing a lowering of cooling efficiency.
Do not remove the thermostat, even if the engine
tends to overheat.

2. REMOVE OIL FILTER
Using SST, remove the oil filter.
SST 09228±06500
3. REMOVE WATER INLET AND THERMOSTAT
(a) Remove the 2 nuts and water inlet from the water
pump.
(b) Remove the thermostat.
(c) Remove the gasket from the thermostat.

7. CHECK ENGINE OIL LEVEL
The oil level should be between the ªLº and ªFº marks
on the dipstick.
If low, check for leakage and add oil up to ªFº mark. (c) Tighten the oil filter by hand until the rubber gasket
contacts the seat of the filter mounting. Then using
SST, give it an additional 3/4 turn to seat the oil filter.
SST 09228±06500
4. FILL WITH ENGINE OIL
5. FILL WITH ENGINE COOLANT (SEE PAGE EG1±241)
6. START ENGINE AND CHECK FOR LEAKS 3. INSTALL OIL FILTER
(a) Clean the oil filter contact surface on the filter
mounting.
(b) Lubricate the filter rubber gasket with engine oil.

RADIATOR ASSEMBLY
(See Components for Disassembly and Assembly)
1. A/T:
INSTALL OIL COOLER TO LOWER TANK
(a) Clean the 0±ring contact surface of the lower tank
and oil cooler.
(b) Install new 0±rings (1) to the oil cooler (2).
(c) Install the oil cooler with the 0±rings to the lower
tank (3).
(d) Install the plate washers (4) and nuts (5). Torque the
nuts.
Torque: 8.3 N±m (85 kgf±cm, 74 in.±lbf)
(e) Install the pipes (6).
Torque: 22 N±m (220 kgf±cm, 16 ft±lbf)
HINT: Face the pipes in the same direction as before
disassembly.4. A/T:
REMOVE OIL COOLER FROM LOWER TANK
(a) Remove the pipes.
HINT: Make a note of the direction to face the pipes.
(b) Remove the nuts and plate washers.
(c) Remove the oil cooler and 0±rings. 3. REMOVE TANKS AND O±RINGS
(a) Lightly tap the radiator hose inlet (or outlet) with a
soft±faced hammer and remove the tank.

If not within the specified height, adjust the stopper
bolt of the handle again and perform the caulking
again.wThe points shown in the illustration and oil cooler
near here (A/T) cannot be staked with the SST.
Use a plier or like object and be careful not to
damage the core plates. After repeating this a few times, fully caulk the lock
plate by squeezing the handle until stopped by the
stopper plate.
