<2.4L ENGINE> Drive Belt Tension Check and
Adjustment

Check the drive belt tension by the following procedure.
<When using scan tool MB991502>

Required Special Tools:

•

MB991502: Scan Tool (MUT-II)

•

MB991668: Belt Tension Meter Set

Gently tap the middle of the belt between the pulleys (the
location indicated by the arrow) with your finger as shown in the
illustration, and check that the vibration frequency of the belt is
within the standard value range.

NOTE: Refer to

P.00-40

for details on the method of measuring

the vibration frequency using the scan tool.

<When using a tension gauge>
Use a belt tension gauge to check that the belt tension is within
the standard value.

<Belt deflection check>
Apply 98 N (22 pound) of force to the middle of the drive belt
between the pulleys (at the place indicated by the arrow) and
check that the amount of deflection is within the standard value.

Standard value:

<2.4L ENGINE>

11. ENGINE OIL FILTER (REPLACE)

M1001002700099

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
withstanding a pressure of 1,765 kPa (256 psi) are high quality
filters and are recommended as follows:

Mitsubishi Oil Filter Part Number:

<2.4L Engine>
MD136466, MD322508, MD325714, MD332687
MD360935, MD365876 or equivalent
<3.0L Engine>
MD352626 or equivalent

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 can withstand a pressure of 1,765
kPa (256 psi) [manufacturer's specifications] to avoid the filter
and engine damage. The following is a high-quality filter and is
strongly recommended for use on this vehicle: Mitsubishi
Engine Oil Filter Part number MD136466, MD322508,
MD325714, MD332687, MD352626, MD360935 and
MD365876.
Any replacement oil filter should be installed in accordance with
the oil filter manufacturer's installation instructions.
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 contacting surface of the filter bracket.

4. Lubricate the O-ring of the new oil filter with a small amount

of new engine oil.

5. Screw on the oil filter by hand until it touches the surface of

the flange and then tighten it with the oil filter wrench: etc.

6. Add new engine oil through the oil filter.
