FOR MEXICO : Engine Coolant Mixture Ratio

INFOID:0000000006826782

The engine cooling system is filled at the factory with a high-quality, year-round and extended life engine cool-

ant. The high quality engine coolant contains the specific solutions effective for the anti-corrosion and the anti-

freeze function. Therefore, additional cooling system additives are not necessary.

WARNING:

Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-

sure fluid escaping from the radiator. Wait until the engine and radiator cool down.

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 cylinder block drain plugs (A), (B), (C), (D) and

block heater if equipped, to drain the cylinder block as shown.

CAUTION:

Do not reuse copper sealing washers.

NOTE:

For Canada, the (D) cylinder block drain plug as shown, is not a

cylinder block drain plug but a block heater.

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-24, "ENGINE COOLANT :

Changing Engine Coolant"

REFILLING ENGINE COOLANT

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

block drain plugs (A), (B), (C), (D) and block heater if equipped,

if removed for a total system drain or for engine removal or

repair.

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"

(United States and Canada),

MA-20, "FOR MEXICO :

(Mexico).

CAUTION:

Never 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. 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
