WARNING:

Be sure to perform when the engine is stopped.

1. Remove air duct and resonator assembly when inspecting drive belt.
2. Make sure that indicator (single line notch) of each auto tensioner is within the allowable working range

(between three line notches).

NOTE:

• Check the drive belt auto tensioner indication when the engine is cold.

• The indicator notch is located on the moving side of the drive belt auto tensioner. 

3. Visually check entire belt for wear, damage or cracks.
4. If the indicator is out of allowable working range or belt is damaged, replace the belt. Refer to 

EM-152,

"Removal and Installation"

.

ENGINE COOLANT
ENGINE COOLANT : System Inspection

INFOID:0000000007347371

WARNING:

• Never remove the radiator/reservoir cap when the engine is hot. Serious burns could occur from

high pressure fluid escaping from the radiator or reservoir.

• Wrap a thick cloth around the cap. Slowly push down and turn it a quarter turn to allow built-up pres-

sure to escape. Carefully remove the cap by pushing down and turning it all the way.

• Damage

• Loose connections

• Chafing

• Deterioration

CHECKING RESERVOIR LEVEL 

• Check if the engine coolant reservoir tank level is within MIN to

MAX level when the engine is cool.

• Adjust engine coolant level as necessary.

ENGINE COOLANT : Changing Engine Coolant

INFOID:0000000007347372

WARNING:

• To avoid being scalded, never change the coolant when the engine is hot.

• Wrap a thick cloth around the cap to carefully remove the cap. First, turn the cap a quarter of a turn

to release any built-up pressure, then push down and turn the cap all the way to remove it.

DRAINING ENGINE COOLANT

1. Turn ignition switch ON and set temperature control lever all the way to HOT position or the highest tem-

perature position. Wait 10 seconds and turn ignition switch OFF.

2. Remove the engine front under cover using power tool. Refer to 

EXT-15, "Removal and Installation"

.

3. Open the radiator drain plug at the bottom of the radiator, and

remove the reservoir cap. This is the only step required when

partially draining the cooling system (radiator only). 

CAUTION:

Do not allow the coolant to contact the drive belts. 

4. When draining all of the coolant in the system for engine

removal or repair, it is necessary to drain the cylinder block.

Remove the RH cylinder block drain plug to drain the right bank,

the oil cooler hose to drain the left bank as shown.

5. Remove the reservoir tank to drain the engine coolant, then clean the reservoir tank before installing it.
6. Check the drained coolant for contaminants such as rust, corrosion or discoloration.

If the coolant is contaminated, flush the engine cooling system. Refer to 

MA-34, "ENGINE COOLANT :

Changing Engine Coolant"

.

REFILLING ENGINE COOLANT

1. Close the radiator drain plug. Install the reservoir tank, cylinder

block drain plug, and the oil cooler hose if removed for a total

system drain or for engine removal or repair.

• The radiator must be completely empty of coolant and water.

• Apply sealant to the threads of the cylinder block drain plug.

Use Genuine High Performance Thread Sealant or equivalent.

Refer to 

GI-14, "Recommended Chemical Products and Seal-

ants"

.

2. Set the vehicle heater controls to the full HOT and heater ON position. Turn the vehicle ignition ON with

the engine OFF as necessary to activate the heater mode.

3. Remove the vented reservoir cap and replace it with a non-vented reservoir cap before filling the cooling

system.

4. Install the Tool by installing the radiator cap adapter onto the

radiator neck opening. Then attach the gauge body assembly

with the refill tube and the venturi assembly to the radiator cap

adapter.

5. Insert the refill hose into the coolant mixture container that is

placed at floor level. Make sure the ball valve is in the closed

position. 

• Use recommended coolant or equivalent.

Refer to 

MA-18, "FOR USA AND CANADA : Fluids and Lubri-

cants"

.

6. Install an air hose to the venturi assembly, the air pressure must

be within specification.

ENGINE MAINTENANCE (VK56DE)

CAUTION:

The compressed air supply must be equipped with an air dryer.

7. The vacuum gauge will begin to rise and there will be an audible hissing noise. During this process open

the ball valve on the refill hose slightly. Rising coolant will be visible in the refill hose. After the refill hose is

full of coolant, close the ball valve. This will purge air trapped in the refill hose.

8. Continue to draw the vacuum until the gauge reaches 28 inches

of vacuum. The gauge may not reach 28 inches in high altitude

locations. Refer to the following table for expected vacuum read-

ings.   

9. When the vacuum gauge has reached the specified amount, disconnect the air hose and wait 20 seconds

to see if the system loses vacuum. If the vacuum level drops, perform necessary repairs to the system

and repeat steps 6 - 8 to bring the vacuum to the specified amount. Recheck for leaks. 

10. Place the coolant container (with the refill hose inserted) at the same level as the top of the radiator. Then

open the ball valve on the refill hose so the coolant will be drawn up to fill the cooling system. The cooling

system is full when the vacuum gauge reads zero.

CAUTION:

Do not allow the coolant container to get too low when filling, to avoid air from being drawn into

the cooling system. 

11. Remove the Tool from the radiator neck opening and install the radiator cap.
12. Remove the non-vented reservoir cap.
13. Fill the cooling system reservoir tank to the specified level. Run the engine to warm up the cooling system

and top up the system as necessary before installing the vented reservoir cap.

FLUSHING COOLING SYSTEM

1. Drain the water from the engine cooling system. Refer to 

CO-12, "Changing Engine Coolant"

.

2. Fill the radiator and the reservoir tank (to the “MAX” line), with water. Reinstall the radiator cap and leave

the vented reservoir cap off.

3. Run the engine until it reaches normal operating temperature.
4. Press the engine accelerator two or three times under no-load.
5. Stop the engine and wait until it cools down.
6. Drain the water from the engine cooling system. Refer to 

CO-12, "Changing Engine Coolant"

.

7. Repeat steps 2 through 6 until clear water begins to drain from the radiator.

FUEL LINES
FUEL LINES : Checking Fuel Line

INFOID:0000000007347373

Inspect fuel lines, fuel filler cap and fuel tank for improper attach-

ment, leaks, cracks, damage, loose connections, chafing or deterio-

ration.

If necessary, repair or replace damaged parts.
