ENGINE COOLANT

5. When performing a complete cooling system drain remove the cylinder block front drain plug and the cyl-

inder block RH drain plug.

6. Check the drained coolant for contaminants such as rust, corrosion or discoloration.

• If contaminated, flush the engine cooling system. 

REFILLING ENGINE COOLANT

1. Install the radiator drain plug. If the cooling system was drained completely, install the reservoir tank and

the cylinder block drain plugs.

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

• Apply sealant to the threads of the cylinder block drain plugs. Use Genuine High Performance Thread

Sealant or equivalent. Refer to 

GI-21, "Recommended Chemical Products and Sealants"

.

2. If disconnected, reattach the upper radiator hose at the engine side.
3. 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.

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-16, "FOR USA AND CANADA : Anti-Freeze Cool-

ant Mixture Ratio"

 (United States and Canada) or 

MA-17,

"FOR MEXICO : Engine Coolant Mixture Ratio"

 (Mexico).

CAUTION:

Do not use any cooling system additives such as radiator

sealer. Additives may clog the cooling system and cause

damage to the engine, transmission and/or cooling system.

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

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. Coolant will be visible rising in the refill hose. Once the refill hose is

full of coolant, close the ball valve. This will purge any 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; use the vacuum specifications based on the altitude

above sea level.

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

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

system and repeat steps 6 - 8 to bring the vacuum to the specified amount. Recheck for any 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.
12. Fill the cooling system reservoir tank to the specified level and install the radiator cap. Run the engine to

warm up the cooling system and top up the system as necessary.

13. Install the engine under cover. Refer to 

EXT-15, "Exploded View"

.

FLUSHING COOLING SYSTEM

1. Fill the radiator from the filler neck above the radiator upper hose and reservoir tank with clean water and

reinstall radiator cap. 

2. Run the engine and warm it up to normal operating temperature.
3. Rev the engine two or three times under no-load.
4. Stop the engine and wait until it cools down.
5. Drain the water from the system. Refer to 

CO-11, "Changing Engine Coolant"

.

6. Repeat steps 1 through 5 until clear water begins to drain from the radiator.

WARNING:

Do not remove the radiator cap when the engine is hot. Serious burns could occur from high pressure

coolant escaping from the radiator. Wrap a thick cloth around the radiator cap. Slowly turn it a quarter

turn to allow built-up pressure to escape. Carefully remove the radiator cap by turning it all the way.    

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-

ing.

9. Remove radiator.

CAUTION:

Do not damage or scratch the radiator core when removing.

INSTALLATION

Installation is in the reverse order of removal.

• After installation refill engine coolant and check for leaks. Refer to   and 

CO-10, "System Inspection"

CAUTION:

Do not spill coolant in engine compartment. Use a shop cloth to absorb coolant.

INSPECTION

Radiator

1. Check radiator for mud or clogging. If necessary, clean radiator as follows.

CAUTION:

• Be careful not to bend or damage the radiator fins.

• When radiator is cleaned on-vehicle, remove surrounding parts in order to access the radiator

core. Tape the harness and electrical connectors to prevent water from entering.

2. Spray water to the back side of the radiator core using a side to side motion from the top down. 
3. Stop spraying when debris no longer flows from radiator core. 
4. Blow air into the back side of radiator core using a side to side motion from the top down.

• Use compressed air lower than 490 kPa (5 kg/cm

2

, 71 psi) and keep distance more than 30 cm (11.8 in). 

5. Continue to blow air until no water sprays out.
6. Inspect radiator for leaks as follows:
a. Apply pressure using Tool.

WARNING:

To prevent the risk of the hose coming undone while under

pressure, securely fasten it down with a hose clamp.

Attach a hose to the oil cooler as well.

b. Check for leaks.
