ENGINE COOLANT
System InspectionINFOID:0000000009460413
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.

2. Pull the negative-pressure valve to open it and check that it
closes completely when released.
• Check that there is no dirt or damage on the valve seat of the
radiator cap negative-pressure valve.
• Check that there are no abnormalities in the opening and clos- ing conditions of the negative-pressure valve.
3. Check radiator cap relief pressure using suitable tool and Tool. • When connecting the radiator cap to the tester, apply water orcoolant to the cap seal surface.
• Replace the radiator cap if there is an abnormality in the nega-
tive-pressure valve, or if the open-valve pressure is outside of
the standard values.
CHECKING RADIATOR
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 surr ounding parts in order to access the radiator core.
Tape the harness and electrical connectors to prevent water from entering.
1. Spray water to the back side of the radiator co re using a side to side motion from the top down.
2. Stop spraying when debris no longer flows from radiator core.
3. 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).
4. Continue to blow air until no water sprays out.
5. Check for coolant leaks. Repair as necessary.
Changing Engine CoolantINFOID:0000000009460414
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 th ick 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.
DRAINING ENGINE COOLANT
1. Remove the engine under cover. Refer to EXT-17, "Removal and Installation".
2. Open the radiator drain plug at the bottom of the radi ator and remove the radiator filler cap. This is the
only step required when partially draining the cooling system (radiator only).
CAUTION:
• Do not allow the coolant to contact the drive belts.
• Perform this step when engine is cold.
3. Follow this step for heater core removal/replac ement only. Disconnect the upper heater hose at the
engine side and apply moderate air pressure [103.46 kPa (1.055 kg/cm
2, 15 psi) maximum air pressure]
into the hose for 30 seconds to blow t he excess coolant out of the heater core.
4. When draining all of the coolant in the system, re move the reservoir tank and drain the coolant, then clean
the reservoir tank before 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.
