1. DRAIN ENGINE COOLANT FROM RADIATOR
HINT:
It is not necessary to drain out all the coolant.
2. REMOVE ECT SWITCHES
(a) Disconnect the connector.
(b) Remove the ECT switch.
3. 5S±FE engine:
INSPECT ECT SWITCH CONTINUITY
(a) Using an ohmmeter, check that no continuity exists be-
tween the terminals when the coolant temperature is
above 93°C (199°F).
If continuity exists, replace the switch.
(b) Using an ohmmeter, check that continuity exists between
the terminals when the coolant temperature is below
83°C (181°F).
If no continuity exists, replace the switch.
4. 1MZ±FE engine:
INSPECT No. 1 SWITCH CONTINUITY
(a) Using an ohmmeter, check that no continuity exists be-
tween the terminals when the coolant temperature is
above 98°C (208°F).
If continuity exists, replace the switch.
(b) Using an ohmmeter, check that continuity exists between
the terminals when the coolant temperature is below
88°C (190°F).
If no continuity exists, replace the switch.

INSPECT No. 2 SWITCH CONTINUITY
(a) Using an ohmmeter, check that no continuity exists be-
tween the terminal and switch body when the coolant
temperature is above 93°C (199°F).
If continuity exists, replace the switch.
(b) Using an ohmmeter, check that continuity exists between
the terminals when the coolant temperature is below
83°C (181°F).
If no continuity exists, replace the switch.
6. INSTALL ECT SWITCHES
(a) Install the ECT switch.
HINT:
Lubricate a new O±ring with soapy water and install the switch.
(b) Connect the connector.
