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.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.

INSTALLATION
Installation is in the reverse order of removal.
• Install the engine coolant temperature sensor. Use Genuine RTV Silicone Seal ant or equivalent. Refer to GI-21, "Recommended Chemical Products
and Sealants".
• Install the heater pipe, first apply a mild soap to t he O-ring and quickly insert the heater pipe into the hous-
ing.
CAUTION:
• Do not reuse O-ring.
• Do not reuse gasket.
• Do not reuse water outlet.
• After installation, refill coolant and check for leaks. Refer to CO-12, "Changing 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.
