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

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.

4. Drain the water in the water jacket by unplugging the drain
plug of the cylinder block.
5. Remove the radiator condenser tank assembly and drain the
coolant.
6. Drain the coolant then clean the path of the coolant by
injecting water into the radiator from the radiator cap area.
7. Apply the designated sealant to the screw area of the
cylinder block drain plug, and then tighten to the standard
torque.
Specified sealant: Loctite 577 or equivalent
Tightening torque:
<3.8L Engine> 39
5 Nm
8. Securely tighten the radiator drain plug.
9. Assemble the radiator condenser tank assembly.
Do not use alcohol or methanol anti-freeze or any engine
coolants mixed with alcohol or methanol anti-freeze. The
use of an improper anti-freeze can cause corrosion of the
aluminum components.
10.By referring to the section on coolant, select an appropriate
concentration for safe operating temperature within the
range of 30 to 60%. Use special tool MB991871 to refill the
coolant. A convenient mixture is a 50% water and 50%
antifreeze solution [freezing point:
31C (32.8 F)].
Recommended antifreeze: Long Life Antifreeze
Coolant or an equivalent
Quantity:
<3.8L Engine> 8.7 Litres
NOTE: For how to use special tool MB991871, refer to its
manufacturer’s instructions.
11.Reinstall the radiator cap.
12.Start the engine and let it warm up until the thermostat
opens.
13.After repeatedly revving the engine up to 3,000 r/min
several times, stop the engine.

14.Remove the radiator cap after the engine has cooled, and
pour in coolant up to the brim. Reinstall the cap.
Do not overfill the radiator condenser tank assembly.
15.Add coolant to the radiator condenser tank assembly
between the "FULL" and "LOW" mark if necessary.
13. COOLANT HOSES (RADIATOR HOSE,
HEATER HOSE) (INSPECT)
M1001009700034
Inspect the surface of radiator hoses and heater hoses for heat
and mechanical damage. Hard and brittle rubber, cracking,
tears, cuts, abrasions and excessive swelling indicate deterio-
ration of the rubber.
14. DISC BRAKE PADS, ROTORS (INSPECT FOR
WEAR)
M1001003200291
Check for fluid contamination and wear. Replace the complete
set of pads if any one pad is defective.
Thickness of lining
Minimum limit: 2.0 mm
The pads for the right and left wheels should be replaced
at the same time. Never split or intermix brake pad sets. All
four pads must be replaced as a complete set.
15. BRAKE HOSES (CHECK FOR
DETERIORATION OR LEAKS)
M1001003400314
Inspection of brake hoses should be included in all brake ser-
vice operations.
The hoses should be checked for:
1. Incorrect length, severe surface cracking, stretching,
scuffing or worn spots (If the fabric casing of the hoses is
exposed by cracks or abrasion in the rubber hose cover, the
hoses should be replaced. Eventual deterioration of the
hose and possible bursting failure may occur).
2. Incorrect installation, twisting or interference with wheel, tyre
or chassis.
