Thermostat and Water Piping
REMOVAL AND INSTALLATION
+Be careful not to spill coolant over engine compartment.
Use a rag to absorb coolant.
1. Drain engine coolant. Refer to ªChanging Engine Coolantº in
MA section.
2. Remove water inlet.
3. Remove thermostat.
4. Install thermostat with jiggle valve facing upward.
+Carefully install the rubber ring to the flange of the
thermostat, making sure it does not slip out of place.
5. After installation and refilling coolant, run engine for a few
minutes, and check for leaks.

INSPECTION
1. Check valve seating condition at ordinary room tempera-
tures. It should seat tightly.
2. Check valve opening temperature and maximum valve lift.
Standard
Valve opening temperature Above 80 - 84ÉC (176 - 183ÉF)
Valve lift More than 10 mm/95ÉC
(0.39 in/203ÉF)
3. Then check if valve closes at 5ÉC (9ÉF) below valve opening
temperature.
Radiator
REMOVAL AND INSTALLATION
1. Remove under guard.
2. Drain engine coolant. Refer to MA section, ªChanging Engine
Coolantº.
3. Remove radiator shroud (lower).
4. Remove radiator shroud (upper).
5. Disconnect radiator hose (upper and lower).
6. Disconnect reservoir tank hose.
7. Remove radiator.
8. After repairing or replacing radiator, install all removed parts
in reverse order of removal.

MODEDescription
C/U INITIALIZATION When replacing any of the following components, C/U initialization is necessary.
[NATS ignition key/IMMU/ECM/Dongle unit]
SELF-DIAG RESULTS Detected items (screen terms) are as shown in the chart below.
NOTE:
When any initialization is performed, all ID previously registered will be erased. So all NATS ignition
keys must be registered again.
The engine cannot be started with an unregistered key. In this case, the system may show ªDIFFER-
ENCE OF KEYº or ªLOCK MODEº as a self-diagnostic result on the CONSULT-II screen.
When initialization is performed (for RHD models), security indicator will flash six times to demon-
strate recognition of dongle unit ID.
