3. Adjust the belt tension by turning the adjusting bolt. Refer to 

EM-115, "Drive Belt"

.

CAUTION:

• When checking immediately after installation, first adjust it to the specified value. Then, after

turning crankshaft two turns or more, readjust to the specified value to avoid variation in deflec-

tion between pulleys.

• When the tension adjustment is performed, the lock nut should be in the condition at Step 2. If

the tension adjustment is performed when the lock nut is loosened more than the temporary

tightening, the idler pulley tilts and the correct tension adjustment cannot be performed.

4. Tighten the lock nut to final tightening specification.

CHECKING COOLING SYSTEM HOSES

Check hoses for the following:

• Improper attachment

• Leaks

• Cracks

• Damage

• Loose connections

• Chafing

• Deterioration

CHECKING RESERVOIR LEVEL 

• Check that the reservoir tank engine coolant level is within the

MAX (A) to MIN (B) range when the engine is cool.

• Adjust the engine coolant level if necessary.

CAUTION:

Refill the engine cooling system with the specified coolant or

equivalent. Refer to 

MA-12, "Fluids and Lubricants"

.

CHECKING COOLING SYSTEM FOR LEAKS

WARNING:

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

engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly push down and

turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down

and turning it all the way.

CAUTION:

• Perform this step when the engine is cold.

• Do not spill engine coolant on drive belt.

ENGINE COOLANT : Draining Engine Coolant

INFOID:0000000009670483

WARNING:

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

engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly push down and

turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down

and turning it all the way.
1. Remove front under cover. Refer to 

EXT-25, "FRONT UNDER COVER : Removal and Installation"

.

2. Connect a suitable hose to the radiator drain plug.

• Use a suitable hose with the dimensions as shown.

3. Open radiator drain plug (A) at the bottom of radiator, and then

remove radiator cap. 

(A): Suitable hose

: Front

CAUTION:

• Perform this step when engine is cold.

• Do not spill engine coolant on the drive belt.

4. It is necessary to drain the cylinder block when draining all of engine coolant in the system. To drain the

cylinder block, open the water drain plugs on cylinder block. Refer to 

EM-92, "Exploded View"

.

5. Remove reservoir tank if necessary, and drain engine coolant and clean reservoir tank before installing.

Refer to 

CO-14, "Exploded View"

.

6. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated,

flush the engine cooling system. Refer to 

CO-11, "Flushing Cooling System"

.

ENGINE COOLANT : Refilling

INFOID:0000000009670484

1. Install the radiator drain plug. Install the reservoir tank and cylinder block drain plug, if removed for a total

system drain or for engine removal or repair.

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

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

Thread Sealant or equivalent. Refer to 

MA-12, "Fluids and Lubricants"

.

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 engine coolant mixture container

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

closed position. 

• Use recommended engine coolant or equivalent. 

Refer to 

MA-12, "Fluids and Lubricants"

.

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. Engine coolant will be visible rising in the refill hose. Once the refill

hose is full of engine 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 engine coolant container (with the refill hose inserted) at the same level as the top of the radia-

tor. Then open the ball valve on the refill hose so the engine coolant will be drawn up to fill the cooling sys-

tem. The cooling system is full when the vacuum gauge reads zero.
