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.

DRAINING ENGINE COOLANT
1. Open radiator drain plug (1) at the bottom of radiator, and
remove radiator cap.
CAUTION:
Be careful not to allow engine coolant to contact drive belts.
When draining all engine coolant in the system, also perform the following steps.
2. Remove air relief plug (1) on heater feed tube.
lLHD models
lRHD models
3. Open cylinder block drain plug. Refer toEM-110, "
CYLINDER BLOCK".
4. Remove reservoir tank, drain engine coolant, then clean reservoir tank.
5. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush engine cooling system. Refer toCO-9, "
FLUSHING COOLING SYSTEM".
REFILLING ENGINE COOLANT
1. Install reservoir tank, and radiator drain plug.
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring.
lIf water drain plugs on cylinder block are removed, close and tighten them. Refer toEM-110,
"CYLINDER BLOCK".
2. Make sure that each hose clamp has been firmly tightened.

WARNING:
Do not remove radiator cap and/or reservoir tank cap when engine is hot. Serious burns could occur
from high-pressure engine coolant escaping from radiator and/or reservoir tank.
REMOVAL
1. Drain engine coolant from radiator. Refer toCO-8, "DRAINING ENGINE COOLANT".
CAUTION:
lPerform this step when engine is cold.
lDo not spill engine coolant on drive belts.
2. Remove battery. Refer toSC-5, "

3. Remove engine cover. Refer toEM-20, "INTAKE MANIFOLD".
4. Remove air inlet hoses between engine to charge air cooler. Refer toEM-18, "
CHARGE AIR COOLER".
5. Disconnect radiator hose (upper and lower) and reservoir tank hose.
CAUTION:
Be careful not to allow engine coolant to contact drive belts.
6. Remove reservoir tank.
7. Remove cooling fans (crankshaft driven type and motor driven type) and radiator shrouds (upper and
lower). Refer toCO-19, "
COOLING FAN".
8. Disconnect A/T fluid cooler hoses. (A/T models)
lInstall blind plug to avoid leakage of A/T fluid.
9. Remove radiator mounting brackets.
10. Remove the two A/C condenser bolts. (models with A/C)
11. Remove radiator.
Remove radiator as follows (models with A/C):
CAUTION:
Do not damage or scratch A/C condenser and radiator core when removing.
a. With lifting and pulling radiator (3) in a rear direction, remove
radiator lower mount (4) from radiator core support (1).
CAUTION:
Because A/C condenser (2) is onto the front-lower portion
of radiator (3), moving to rear direction should be at mini-
mum.
b. Lift A/C condenser up and remove radiator.
CAUTION:
Lifting A/C condenser should be minimum to prevent a load
to A/C piping.
c. After removing radiator, temporarily secure it with rope or similar
means to prevent a load to A/C piping.
