(ECT SENSOR)
Removal
1) Disconnect battery negative cable at battery.
2) Drain coolant referring to Section 6B.
WARNING:
To help avoid danger of being burned, do not remove ra-
diator cap while engine and radiator are still hot.
Scalding fluid and steam can be blown out under pres-
sure if cap is taken off too soon.
3) Disconnect coupler from ECT sensor.
4) Remove ECT sensor (1) from thermostat case.
Inspection
Immerse temperature sensing part of ECT sensor (1) in water (or
ice) and measure resistance between terminal “A” and “B” while
heating water gradually.
If measured resistance doesn’t show such characteristic as shown
in left figure, replace ECT sensor (1).
Installation
