1. Check for holes and exhaust gas leaks due to damage,
corrosion, etc.
2. Check the joints and connections for looseness and exhaust
gas leaks.
3. Check the rubber hangers and brackets for damage.
9. ENGINE OIL (CHANGE)M1001002600360
Use the specified oil. (Refer to P.00-35.)
Use care as oil could be hot.
1. After warming up the engine, remove the oil filler cap.
2. Remove the drain plug to allow the engine oil to drain.
3. Install a new drain plug gasket so that it faces in the
direction shown in the illustration, and then tighten the drain
plug to the specified torque.
Tightening torque: 39
5 Nm (29 3 ft-lb)
4. Pour new engine oil in through the oil filler hole.
Specified Engine Oil:
To ta l q u a n t i t y :
<3.8L Engine> 4.6 Litres
5. Install the engine oil filler cap.
6. Start the engine and run it at idle for a few minutes.
7. Pull out the oil dipstick slowly and check that the oil level is
within the marks on the oil dipstick.
8. Check that the oil is not excessively dirty, that there is no
coolant or petrol mixed in, and that it has sufficient viscosity.
10. ENGINE OIL FILTER (REPLACE)M1001002700345
The quality of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient service.
Genuine oil filters require that the filter is capable of withstand-
ing a pressure of 1,800 kPa (261 psi) are high quality filters.

Engine Oil Filter Selection
This vehicle is equipped with a full-flow, throw-away oil filter.
The same type of filter is recommended as a replacement filter
for this vehicle. It is possible, particularly in cold weather, that
this vehicle may develop high oil pressure for a short duration.
Make sure that any replacement filter used on this vehicle is a
high-quality filter. The filter must withstand a pressure of 1,800
kPa (261 psi) [manufacturer's specifications] to avoid filter and
ultimately engine damage. The Genuine Mitsubishi high-quality
filter and is strongly recommended for use on this vehicle.
Any replacement oil filter should be installed in accordance with
the oil filter manufacturer's installation instructions.
.
Oil Filter Replacement
Use care as oil could be hot.
1. Drain the engine oil by removing the oil drain plug.
2. Use an oil filter wrench to remove the engine oil filter.
3. Clean the filter bracket side mounting surface and ensure
the old O-ring has been removed.
4. Apply a small amount of engine oil to the O-ring of the new
oil filter.
5. Where the oil filter O-ring touches the oil pan flange, tighten
the oil filter to the specified torque using the
commercially-available tool.
Tightening torque:
: Approximately 3/4 turn [14
2 Nm]
6. Add new engine oil through the oil filler.
11. TRANSMISSION FLUIDM1001002900338
TRANSMISSION FLUID CHECK
1. Drive the vehicle until the transmission fluid temperature
rises to the normal operating temperature [70
80C (158
176
F)].
NOTE: The transmission fluid temperature is measured with
Diagnostic Tool (MUT-III).

6. Securely insert the dipstick.
NOTE: The transmission fluid should always be replaced
under the following conditions:
.
When troubleshooting the transaxle.
When overhauling the transaxle.
When the transmission fluid is noticeably dirty or burnt
(driving under severe conditions).
TRANSMISSION FLUID CHANGE
Refer to GROUP 23A, Automatic Transmission - On-vehicle
Service P.23A-296.
12. ENGINE COOLANT (CHANGE)M1001003100357
Check the cooling system parts such as the radiator, heater
and oil cooler hoses, thermostat and their connections for leak-
age and damage.
.
CHANGING COOLANT
1. Set the temperature control knob to the "HOT" position.
2. Run the engine until the engine coolant warms, and then
stop the engine.
When removing the radiator cap, use care to avoid
contact with hot coolant or steam. Place a shop towel
over the cap and turn the cap counterclockwise a lit-
tle to let the pressure escape through the vinyl tube.
After relieving the steam pressure, remove the cap by
slowly turning it counterclockwise.
3. Drain the water from the radiator, heater core and engine
after unplugging the radiator drain plug and removing the
radiator cap.
