+The refill capacity depends on the oil temperature and
drain time. Use these specifications for reference only.
Always use the dipstick to determine when the proper
amount of oil is in the engine.
6. Check oil level as follows.
a. Start engine and check area around drain plug and oil filter
for oil leakage.
b. Run engine for a few minutes, then turn it off. After more than
10 minutes, check oil level.

REMOVAL
1. Place a pan to catch the oil under the lower part of drain hose
outlet before removing filter body.
2. Using a hexagonal socket wrench [plane-to-plane width: 24
mm (0.94 in)], loosen the filter body approximately four turns.
3. Remove the filter body, then remove the oil filter element.
4. Remove the O-ring from the filter body.
+Push the O-ring in one direction, lift the slack part using
fingers, and remove the O-ring from the filter body.
CAUTION:
Do not use wires or flat-bladed screwdrivers etc. as they
may cause damage to the filter body.
INSTALLATION
1. Completely remove all foreign objects adhering to the inside
of the filter body or O-ring mounting area (filter body side and
bracket side).
2. Install the oil filter element and O-ring to the filter body.
+Push the oil filter element into the filter body completely.
3. Install the filter body to the oil filter bracket.
:20-25Nzm (2.0 - 2.6 kg-m, 15 - 18 ft-lb)
4. After warming up the engine, check for engine oil leakage
and oil level.
CAUTION:
Completely wipe clean any engine oil remaining on the fil-
ter body or vehicle.
Changing Engine Coolant
To avoid the danger of being scalded, never change the
coolant when the engine is hot.
Ð DRAINING ENGINE COOLANT Ð
1. Set air conditioning system as follows to prevent coolant from
remaining in the system.
a. Turn ignition switch ON and set temperature controller to
maximum hot position.
b. Wait 10 seconds before turning ignition switch OFF.
2. Open radiator drain plug at the bottom of radiator and
remove radiator cap to drain coolant.

Oil Pressure Check
WARNING:
+Be careful not to burn yourself, as the engine and oil
may be hot.
+Oil pressure check should be done in ªNeutral positionº.
1. Check oil level.
2. Remove oil pressure switch.
3. Install pressure gauge.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load.
Engine speed
rpmApproximate discharge pressure
kPa (bar, kg/cm2, psi)
Idle speed More than 140 (1.40, 1.43, 20.3)
2,000 More than 270 (2.69, 2.75, 39.1)
4,000 More than 430 (4.29, 4.38, 62.3)
If difference is extreme, check oil passage and oil pump
for oil leaks.
6. After the inspections, install the oil pressure switch as fol-
lows.
a. Remove the old sealant adhering to the switch and engine.
b. Apply Genuine Liquid Gasket or equivalent to the thread and
tighten.
