CHECKING COOLING SYSTEM HOSES
Check hoses for the following:
• Improper attachment
• Leaks
• Cracks
• Damage
• Loose connections
• Chafing
• Deterioration
CHECKING RESERVOIR LEVEL
• Check that the reservoir tank engine coolant level is within the
MAX (A) to MIN (B) range when the engine is cool.
• Adjust the engine coolant level if necessary.
CAUTION:
Refill the engine cooling system with the specified coolant or
equivalent. Refer to MA-11, "
Fluids and Lubricants".
CHECKING COOLING SYSTEM FOR LEAKS
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.
CAUTION:
• Perform this step when the engine is cold.
• Do not spill engine coolant on drive belt.
To check for leaks, apply pressure to the cooling system using suit-
able tools (A) and (B).

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.

2. Connect a suitable hose to the radiator drain plug.
• Use a suitable hose with the dimensions as shown.
3. Open radiator drain plug (A) at the bottom of radiator, and then remove radiator cap.
(B): Suitable hose

CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on the drive belt.
4. It is necessary to drain the cylinder block when drai ning all of engine coolant in the system. To drain the
cylinder block, open the water drain plugs on cylinder block. Refer to EM-93, "
Exploded View".
5. Remove reservoir tank if necessary, and drain engine coolant and clean reservoir tank before installing. Refer to CO-13, "
Exploded View".
6. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated,
flush the engine cooling system. Refer to CO-11, "
Flushing Cooling System".

1. Install the radiator drain plug. Install the reservoir tank and cylinder block drain plug, if removed for a total
system drain or for engine removal or repair.
• The radiator must be completely empty of engine coolant and water.
• Apply sealant to the threads of the cylinder block drain plug. Use Genuine High Performance
Thread Sealant or equivalent. Refer to MA-11, "
Fluids and Lubricants".
2. If disconnected, reattach the upper radiator hose at the engine side.
3. Set the vehicle heater controls to the full HOT and heat er ON position. Turn the vehicle ignition ON with
the engine OFF as necessary to activate the heater mode. Diameter (A) : 0.8 mm (0.31 in)

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 engine coolant mixture container that is placed at floor level. Make sure the ball valve is in the
closed position.
•Use recommended engine coolant or equivalent.
Refer to MA-11, "
Fluids and Lubricants".
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, transmission 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. Engine coolant wi ll be visible rising in the refill hose. Once the refill
hose is full of engine 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 engine coolant container (with the refill hose inserted) at the same level as the top of the radia- tor. Then open the ball valve on the refill hose so the engine coolant will be drawn up to fill the cooling sys-
tem. The cooling system is full when the vacuum gauge reads zero.
CAUTION:
Do not allow the engine coolant co ntainer 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 t op up the system as necessary.
13. Install the front under cover. Refer to EXT-39, "

• Check valve seat (A) of 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 mate- rial 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.
• Pull 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 radiator cap negative-pressure valve.
- Check that there are no abnormalities in the opening and closing conditions of negative-pressure valve.
• Check radiator cap relief pressure using suitable tools (A) and (B).
- When connecting the radiator cap to suitable tool (B), apply water or engine coolant to the cap seal surface.
- Replace the radiator cap if ther e is an abnormality in the negative-
pressure valve, or if the open-valve pressure is outside of the stan-
dard values.
RADIATOR
RADIATOR : InspectionINFOID:0000000012432138
Check radiator for mud or clogging. If necessary, clean radiator as follows.
CAUTION:
• Be careful not to bend or damage radiator fins.
• When radiator is cleaned without removal, remove all surrounding parts in order to access the radia-
tor core. Then tape harness and harness conn ectors 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.
3. Blow air into the back side of radiator core using 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 (11.81
in).
4. Continue to blow air until no water sprays out.
5. Check for engine coolant leaks. Repair if necessary.

INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels, including engine coolant and engine oil. If less than required quantity, fill to the specified level. Refer to MA-11, "
Fluids and Lubricants".
• Use procedure below to check for fuel leaks.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks
at connection points.
• Start engine. With engine speed increased, che ck again for fuel leaks at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leaks of fuel, exhaust gas, or any oils/fluids, including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels, including engine oil and engine coolant. Refill to spec- ified level, if necessary.
