WARNING:
Never 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 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. Refer to CO-9, "DRAINING ENGINE COOLANT" .
2. Remove air duct with air cleaner assembly.
3. Remove A/T oil cooler hose.
●Install blind plug to avoid leakage of A/T fluid.
4. Disconnect radiator upper hose, lower hose and mounting bracket.
5. Remove radiator and radiator fan assembly
CAUTION:
Do not damage or scratch radiator core when removing.
INSTALLATION
●Reinstall any parts removed in reverse order of removal.
●Check for engine coolant leaks. Refer to CO-9, "CHECKING RADIATOR SYSTEM FOR LEAKS" .

Precautions For Liquid GasketEBS00MRY
REMOVAL OF LIQUID GASKET
●After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.
●In areas where the cutter is difficult to use, use a plastic hammer
to lightly tap the areas where the liquid gasket is applied.
CAUTION:
If for some unavoidable reason a tool such as a flat-blade
screwdriver is used, be careful not to damage the mating
surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.
●Remove the liquid gasket completely from the groove of the
liquid gasket application surface, mounting bolts and bolt
holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
3. Attach the liquid gasket to the tube presser.
Use Genuine Liquid Gasket or equivalent.
4. Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
●If there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
●As for the bolt holes, normally apply the liquid gasket inside
the holes. If specified, it should be applied outside the holes.
Make sure to read the instruction in this manual.
●Within five minutes of liquid gasket application, install the mat-
ing component.
●If the liquid gasket protrudes, wipe it off immediately.
●Do not retighten after the installation.
●After 30 minutes or more have passed from the installation, fill
the engine oil and engine coolant.
CAUTION:
If there are instructions in this manual, observe them.
