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.
1. DRAIN ENGINE COOLANT (See page EG1±241)
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.

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.

2. INSPECT COOLING SYSTEM FOR LEAKS
(a) Fill the radiator with coolant and attach a radiator cap
tester.
(b) Warm up the engine.
(c) Pump it to 118 kPa (1.2 kgf/cm, 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.
RADIATOR REMOVAL
1. DISCONNECT NEGATIVE (±) TERMINAL CABLE
FROM BATTERY
CAUTION: Work must be started after 90 seconds from
the time the ignition switch is turned to the ªLOCKº
position and the negative (±) terminal cable is discon±
nected from the battery.

(d) Inspect for water leaks.
HINT: On radiators with resin tanks, there is a clear±
ance between the tank and lock plate where a minute
amount of air will remain, giving the appearance of an
air leak when the radiator is submerged in water.
Therefore, before performing the water leak test, first
switch the radiator around in the water until all air
bubbles disappear.
7. PAINT LOCK PLATES
HINT: If the water leak test checks out okay, allow the
radiator to completely dry and then paint the lock
plates.
