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).
|
WATER PUMP
| 1. |
Install the water pump(A) and a new gasket(B)
with the 8bolts.

| 5. |
Fill with engine coolant. (See page EMA -

| 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).

| 4. |
Fill with engine
coolant. |
| 5. |
Start engine and check for

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. | |
