COOLANT
Relationship between Coolant Concentration and Specific Gravity
If the concentration of the coolant is below 30%, the anti-corrosion property will be adversely
affected. In addition, if the concentration is above 50%, both the anti-freeze and engine cooling
properties will decrease, affecting the engine adversely. For these reasons, be sure to maintain
the concentration level within the specified range.
Do not use a mixture of different brands of anti-freeze.
Example
The safe operating temperature is
15C (5 F) when the specific gravity is 1.058 at the coolant temperature

MAINTENANCE SERVICE
1. FUEL SYSTEM (TANK, PIPE LINE AND
CONNECTION, AND FUEL TANK FILLER TUBE
CAP) (CHECK FOR LEAKS)
M1001001600312
Check for damage or leakage in the fuel lines and connections.
2. FUEL HOSES (CHECK CONDITION)M1001001700308
1. Inspect the surface of fuel hoses for heat and mechanical
damage. Hard and brittle rubber, cracking, tears, cuts,
abrasions and excessive swelling indicate deterioration of
the rubber.
2. If the fabric casing of the rubber hose is exposed by cracks
and abrasions in the fuel system, the hose should be
replaced.
3. AIR CLEANER FILTER (REPLACE)M1001001800338
The air cleaner element will become dirty during use, reducing
its effectiveness. Replace it with a new one.
REPLACEMENT OF AIR CLEANER ELEMENT
1. Unclamp the air cleaner housing cover.
2. Remove the air cleaner element and install a new one.
3. When clamping the air cleaner housing cover in place, be
sure that the cover is completely closed.
4. EVAPORATIVE EMISSION CANISTER (CHECK
FOR CLOGGING)
M1001001900324
If the fuel-vapor cannister is clogged or damaged, excess fuel
vapor will escape into the atmosphere causing a strong fuel
vapour smell t emitt from engine compartmrnt. emission. Dis-
connect the line at both ends, and blow it clean with com-
pressed air. Remove the fuel tank filler tube cap from the filler
tube and check to see if there is evidence that the seal makes
improper contact to the filler tube.

5. SPARK PLUGS (REPLACE)M1001002000346
Iridium plugs are used. Use care not to damage the iridium
tips of the plugs. Do not adjust the spark plug gap.
1. Spark plugs must spark properly to assure proper engine
performance and reduce exhaust emission level. Therefore,
they should be replaced periodically with new ones( Refer to
Maintainence Schedule).
Spark plug type
2. The new plugs should be checked for the proper gap.
Spark plug gap: 1.0
1.1 mm
3. Install the spark plugs and tighten to 25
5 Nm (18 4
ft-lb).
6. TIMING BELT (REPLACE)M1001002300273
Replace the belt with a new one according to the vehicle main-
tenance schedule to assure proper engine performance.

WHEN USING DIAGNOSTIC TOOL (MUT-III)
Required Special Tools:
MB991668: Belt Tension Meter Set
Diagnostic Tool (MUT-III)
MB991824: Vehicle Communication Interface (V.C.I.)
MB991910: MUT-III Main Harness A (BLUE)
To prevent damage to DIAGNOSTIC TOOL (MUT-III), always
turn the ignition switch to the "LOCK" (OFF) position
before connecting or disconnecting.
1. Connect Belt Tension Meter Set (MB991668) to V.C.I
(MB991824).
2. Connect MUT-III Main Harness A (BLUE) (MB991910) to
V.C.I (MB991824).
3. Connect MUT-III Main Harness A (BLUE) (MB991910) to the
data link connector.
4. Turn the ignition switch to the "ON" position and select "Belt
Tension" from the menu V.C.I (MB991824) screen.

The temperature of the surface of the belt should be as
close as possible to underhood temperature.
Do not let any contaminants such as water or oil get
onto the microphone.
If strong gusts of wind blow against the microphone or
if there are any loud sources of noise nearby, the val-
ues measured by the microphone may not correspond
to actual values.
If the microphone is touching the belt while the mea-
surement is being made, the values measured by the
microphone may not correspond to actual values.
Do not take the measurement while the vehicle's engine
is running.
5. Hold special tool MB991668 (microphone) to the middle of
the drive belt between the pulleys (at the place indicated by
the arrow), about 10
20 mm (0.4 0.8 inch) away from the
rear surface of the belt and so that it is perpendicular to the
belt (within an angle of
15 degree angle).
6. Gently tap the middle of the belt between the pulleys (the
place 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.
Standard value:
NOTE: Because the frequency depends on the belt material,
confirm Part No. shown on the reverse of the belt.
