InspectionEBS01E6P
LEVEL CHECK
lCheck if the reservoir tank engine coolant level within MIN to
MAX when engine is cool.
lAdjust engine coolant level as necessary.
CHECKING RADIATOR SYSTEM FOR LEAKS
lTo check for leaks of cooling system, apply pressure to the res-
ervoir tank (1) with the radiator cap tester (commercial service
tool) (A) and the radiator cap tester adapter (B) [SST:
EG17650301].
WARNING:
Do not remove reservoir tank cap and/or radiator cap when
engine is hot. Serious burns could occur from high pres-
sure engine coolant escaping from reservoir tank and/or
radiator.
CAUTION:
Higher test pressure than specified may cause cooling system damage.
NOTE:
In a case that engine coolant decreases, replenish radiator and reservoir tank with engine coolant.
lIf anything is found, repair or replace damaged parts.
Changing Engine CoolantEBS01E6Q
WARNING:
lTo avoid being scalded, do not change engine coolant when engine is hot.
lWrap a thick cloth around cap and carefully remove cap. First, turn cap a quarter of a turn to
release built-up pressure. Then turn cap all the way.
lBe careful not to allow engine coolant to contact drive belts.

INSPECTION AFTER REMOVAL
Checking Reservoir Tank Cap
lInspect valve seat of reservoir tank cap.
–Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
–Check if valve seat has no soil and damage.
lPull negative-pressure valve to open it, and make sure that it is
completely closed when released.
–Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.
–Make sure that there are no unusualness in the opening and
closing conditions of negative-pressure valve.
lCheck reservoir tank cap relief pressure.
–When connecting reservoir tank cap to the radiator cap tester
adapter [SST] and the radiator cap tester (Commercial service
tool), apply engine coolant to the cap seal surface.
lReplace reservoir tank cap if there is an unusualness in negative pressure valve, or if the relief pressure
falls below the limit.
CAUTION:
When installing a radiator cap and reservoir tank cap, thoroughly wipe out the radiator and reservoir
tank filler neck to remove any waxy residue or foreign material.
Checking Radiator
Check radiator for mud or clogging. If necessary, clean radiator as follows.
lBe careful not to bend or damage the radiator fins.
lWhen radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator
shroud and horns. Then tape the harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downwards.
2. Apply water again to all radiator core surface once per minute.
3. Stop washing if any stains no longer flow out from the radiator.
4. Blow air into the back side of radiator core vertically downwards.
lUse compressed air lower than 490 kPa (4.9 bar, 5 kg/cm2, 71 psi) and keep distance more than 30 cm
(11.8 in).
5. Blow air again into all the radiator core surface once per minute until no water sprays out.

INSTALLATION
Installation is the reverse order of removal.
INSPECTION AFTER INSTALLATION
lCheck for leaks of engine coolant using the radiator cap tester adapter [SST: EG17650301] and the radia-
tor cap tester (commercial service tool). Refer toCO-7, "
CHECKING RADIATOR SYSTEM FOR LEAKS".
lStart and warm up engine. Visually check if there is no leaks of engine coolant.

5. Make sure that there is no leakage.
Refer toCO-18, "
INSPECTION".
INSPECTION
1. Apply pressure with the radiator cap tester adapter [SST] and
the radiator cap tester (commercial service tool).
WARNING:
To prevent the risk of hose coming undone while under
pressure, securely fasten it down with hose clamp.
CAUTION:
Attach hose to A/T fluid cooler to seal its inlet and outlet. (A/
T models)
2. Check for leakage by soaking radiator in water container with
the testing pressure applied.Testing pressure

WARNING:
Do not remove radiator cap and/or reservoir tank cap when the engine is hot. Serious burns could
occur from high pressure engine coolant escaping from the radiator and/or the reservoir tank.
CAUTION:
lWhen removing water pump assembly, be careful not to get engine coolant on drive belts.
lWater pump cannot be disassembled and should be replaced as a unit.
lAfter installing water pump, connect hose and clamp securely, then check for leaks using radiator
cap tester (commercial service tool) and radiator cap tester adapter [SST: EG17650301].
REMOVAL
1. Remove front engine undercover. Refer toEI-15, "FRONT BUMPER".
2. Drain engine coolant. Refer toCO-8, "
DRAINING ENGINE COOLANT".
CAUTION:
lPerform this step when engine is cold.
lDo not spill engine coolant on drive belts.
3. Remove engine cover. Refer toEM-20, "
INTAKE MANIFOLD".
4. Remove drive belts. Refer toEM-12, "
DRIVE BELTS".
5. Remove water pump pulley. Refer toCO-19, "
Removal and Installation".
lLoosen the pulley bolts after fixing the pulley using a screwdriver etc.
6. Remove water pump.
