The points shown in the rib sides and oil cooler near here
cannot be staked with SST. Use pliers or similar object
and be careful not to damage the core plates.
(b) Check the lock plate height (H) after completing the caulk-
ing.
Plate height (H): 7.4 ± 7.8 mm (0.2959 ± 0.3119 in.)
If not within the specified height, adjust the stopper bolt of the
handle again and caulk again.

ELECTRIC COOLING FAN
ON±VEHICLE INSPECTION
1. CHECK COOLING FAN OPERATION WITH LOW
TEMPERATURE (Below 88°C (190°F))
(a) Turn the ignition switch ON.
(b) Check that the cooling fan stops.
If not, check the cooling fan relay and ECT switch, and check
for a separated connector or severed wire between the cooling
fan relay and ECT switch.
(c) Disconnect the No.1 ECT switch connector.
(d) Check that the cooling fan rotates.
If not, check the fuses, engine main relay, cooling fan relay,
cooling fan, and check for a short circuit between the cooling
fan relay and ECT switch.
(e) Reconnect the No.1 ECT switch connector.
2. CHECK COOLING FAN OPERATION WITH HIGH
TEMPERATURE (Above 98°C (208°F))
(a) Start the engine, and raise coolant temperature to above
98°C (208°F).
(b) Check that the cooling fan rotates.
If not, replace the No.1 ECT switch.
3. INSPECT NO.1 COOLING FAN
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter to the cooling fan connec-
tor.
(c) Check that the cooling fan rotates smoothly, and check
the reading on the ammeter.
Standard amperage: 8.3 ± 11.3 A at 20°C (68°F)
(d) Reconnect the cooling fan connector.

4. INSPECT NO.2 COOLING FAN
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter to the cooling fan connec-
tor.
(c) Check that the cooling fan rotates smoothly, and check
the reading on the ammeter.
Standard amperage: 8.3 ± 11.3 A at 20°C (68°F)
(d) Reconnect the cooling fan connector.
