WATER PUMP
1. |
Drain the engine coolant.
System is under high pressure when the
engine is hot. To avoid danger of releasing scalding engine
coolant, remove the cap only when the engine is
cool. | |
2. |
Remove drive belts. (See page EMA -
13) |
3. |
Remove the timing belt. (See page EMA -
13) |
4. |
Remove the timing belt idler. (See page EMA -
16) |
5. |
Remove the water pump.
Remove the water pump(A) and
gasket(B).

|
THERMOSTAT
Removal of the thermostat would have an
adverse effect, causing a lowering of cooling efficiency. Do not
remove the thermostat, even if the engine tends to
overheat. |
1. |
Remove the engine
cover. |
2. |
Drain engine coolant so its level is below
thermostat. |
3. |
Remove the lower
hose. |
4. |
Remove water inlet(A) and
thermostat(B).

5. |
Fill with engine coolant. (See page EMA -
72) |
6. |
Start engine and check for
leaks. |
7. |
Recheck engine coolant
level. |
THERMOSTAT
1. |
Place thermostat in thermostat
housing.
(1) |
Install the thermostat with the jiggle
valve upward. |
(2) |
Install a new to the
thermostat(B).

| |
2. |
Install water inlet(A).

3. |
Install the lower
hose. |
4. |
Fill with engine
coolant. |
5. |
Start engine and check for
leaks. |
WATER PUMP
1. |
Check each part for cracks, damage or wear,
and replace the coolant pump assembly if
necessary. |
2. |
Check the bearing for damage, abnormal noise
and sluggish rotation, and replace the coolant pump assembly if
necessary. |
3. |
Check for coolant leakage. If coolant leaks
from hole, the seal is defective. Replace the coolant pump
assembly
A small amount of "weeping" from the
bleed hole is
normal. | |
THERMOSTAT
1. |
Immerse the thermostat in water and gradually
heat the water.

|
2. |
Check the valve opening
temperature.
Valve opening temperature : 82°C
(177°F)
Full opening temperature : 95°C
(205°F)
|
If the valve opening temperature is not as
specified, replace the thermostat. |
3. |
Check the valve lift.
Valve lift : 10mm(0.4in.) or more at
95°C (205°F)
|
If the valve lift is not as specified, replace
the
thermostat. | |
