REMOVAL
1. Drain engine coolant. Refer to CO-9, "Changing Engine Coolant" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belt.
2. Remove the following parts.

RH undercover

Drive belt; Refer to EM-13, "DRIVE BELTS" .

Drive belt auto-tensioner; Refer to EM-14, "Removal and Installation of Drive Belt Auto-Tensioner" .
3. Remove water pump.

Engine coolant will leak from cylinder block, so have a receptacle ready below.
CAUTION:

Handle water pump vane so that it does not contact any other parts.

Water pump cannot be disassembled and should be replaced as a unit.
4. Remove water pump housing with the following procedure;
a. Remove alternator. Refer to SC-13, "
CHARGING SYSTEM" .
b. Remove oil level gauge and oil level gauge guide. Refer to EM-27, "
OIL PAN AND OIL STRAINER" .
CAUTION:
Plug the oil level gauge guide opening to prevent oil pan from entering foreign materials.
c. Remove mounting bolts for water pipe.
d. Remove water pump housing.
5. Remove exhaust manifold and three way catalyst assembly. Refer to EM-25, "
EXHAUST MANIFOLD
AND THREE WAY CATALYST" .

CONSULT-II Reference Value in Data Monitor ModeEBS010TA
Specification data are reference values.
On Board Diagnosis LogicEBS010TB
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise. When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction
is indicated.
This self-diagnosis has the one trip detection logic.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to CO-9, "
Changing Engine
Coolant" . Also, replace the engine oil. Refer to LU-8, "Changing Engine Oil" .
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-19, "
Engine Coolant Mixture Ratio" .
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckEBS010TC
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
