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.
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 filler cap.
2. Run the engine until it reaches 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-35, "Changing Engine Coolant"
.
6. Repeat steps 1 through 5 until clear water begins to drain from the radiator.

WARNING:
Never 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 cap. Slowly turn it a quarter turn to
allow built-up pressure to escape. Carefully remove the cap by turning it all the way.
REMOVAL
1. Drain engine coolant from the radiator. Refer to
CO-12, "Changing Engine Coolant"
2. Remove front grille (Sedan only). Refer to
EXT-38, "Removal and Installation"
.
3. Remove front bumper fascia (Coupe only). Refer to
EXT-13, "Removal and Installation"
.
4. Remove engine undercover.
5. Remove front air duct. Refer to

6. Remove A/C condenser. Refer to
HA-42, "Removal and Installation for Condenser"
7. Disconnect radiator upper and lower hoses.
8. Disconnect the CVT oil cooler hoses, if equipped. Plug the hoses to prevent CVT oil loss.
9. Remove radiator.
CAUTION:
• Do not damage or scratch the radiator core when removing.

INSPECTION
Radiator
1. Check radiator for mud or clogging. If necessary, clean radiator as follows:
• Be careful not to bend or damage the radiator fins.
• When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator
shroud and horns. Then tape the harness and electrical connectors to prevent water from entering.
a. Apply water by hose to the back side of the radiator core, point the hose vertically downward.
b. Apply water again to all radiator core surfaces once per minute.
c. Stop washing when no more dirt flows off the radiator.
d. Blow air into the back side of radiator core, point the air hose vertically downward.
• Use compressed air lower than 490 kPa (5 kg/cm
2
, 71 psi) and keep distance more than 30 cm (11.8 in).
e. Blow air again into all the radiator core surfaces once per minute until no water sprays out.
2. 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 (CVT model only).
b. Check for leakage.
Specified pressure
value
: 157 kPa (1.6 kg/cm
