ENGINE COOLANT
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-11, "FOR USA AND CANADA : Fluids and Lubri-
cants".
CAUTION:
Do not use any cooling system additives such as radiator
sealer. Additives may clog th e cooling system and cause
damage to the engine, transm ission 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 vi sible 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 specifi ed 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 insert ed) 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 specif ied level and install the radiator cap. Run the engine to
warm up the cooling system and t op up the system as necessary.
13. Install the engine under cover. Refer to EXT-17, "Removal and Installation"
.

REMOVAL
1. Remove radiator cap and drain coolant from radiator. Refer to
CO-12, "Changing Engine Coolant".
CAUTION:
• Perform this step when the engine is cold.
• Do not spill coolant on the drive belt.
2. Remove front air duct. Refer to EM-84, "Removal and Installation"
.
3. Disconnect coolant reservoir hose from the radiator.
4. Remove fender protector side cover (LH/RH). Refer to EXT-26, "FENDER PROTECTOR : Exploded
View".
5. Disconnect radiator hose (upper) and radiat or hose (lower) from the radiator.
CAUTION:
Do not allow the coolant to contact the drive belt.
NOTE:
The radiator hose clamps on the radiator hose (upper ) and on the radiator hose (lower), are not serviced
separately. Radiator hose clamps are part of the radiator hose assembly and serviced as one unit with the
radiator hose.
6. Disconnect the CVT oil cooler hoses.
7. Remove the front bumper fascia. Refer to EXT-17, "Removal and Installation"
.
8. Remove A/C condenser. Refer to HA-30, "COMPRESSOR : Removal and Installation"
.
CAUTION:
Be careful not to damage condenser core.
9. Remove the radiator mounts (upper).
10. 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 coolant and check for leaks. Refer to CO-12, "Changing Engine Coolant"

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.
CHECKING COOLING SYSTEM HOSES
Check hoses for the following:
• Improper attachment
• Leaks
•Cracks
• Damage
• Loose connections
• Chafing
• Deterioration
CHECKING RESERVOIR LEVEL
• Check if the reservoir tank coolant level is within MIN to MAX
range when the engine is cool.
• Adjust coolant level if it is too much or too little.
CHECKING COOLING SYSTEM FOR LEAKS
To check for leaks, apply pressure to the cooling system using suit-
able tool (A) and Tool (B).
WARNING:
Do not remove the radiator cap wh en the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
CHECKING RADIATOR CAP
1. Inspect the radiator cap. • Replace the cap if the metal plunger cannot be seen around the edge of the black rubber gasket.
• Replace the cap if deposits of waxy residue or other foreign material are on the black rubber gasket or
the metal retainer.
NOTE:
Thoroughly wipe out the radiator filler neck to remove any waxy residue or foreign material.
