7-8 COOLING AND LUBRICATION SYSTEM • If the ECT sensor ohmic value does not change in the propor- tion indicated, replace it with a new one. Temperature sensor specification Temperature Standard resistance 20 °C (68 °F) Approx. 2.45 kΩ 50 °C (122 °F) Approx. 0.811 kΩ 80 °C (176 °F) Approx. 0.318 kΩ 110 °C (230 °F) Approx. 0.142 kΩ Cooling fan operating temperature: Standard (OFF→ON): Approx. 105 °C (221 °F) (ON→OFF): Approx. 100 °C (212 °F) NOTE: As coolant temperature rises, the cooling fan operates for 5 sec- onds when the temperature arrives each at 50 °C (122 °F), 70 °C (158 °F) and 90 °C (194 °F)/above 4 000 r/min. If the resistance is noted to show infinity or too much different resistance value, replace the ECT sensor with a new one.  E * Take special care when handling the ECT sensor. It may cause damage if it gets a sharp impact. L * Do not contact the ECT sensor and the column ther-P mometer with a pan. M INSTALLATION A • Tighten the ECT sensor to the specified torque. S ECT sensor: 18 N·m (1.8 kgf-m, 13.0 lb-ft)  Take special care when handling the ECT sensor. It may cause damage if it gets a sharp impact. • Install the fuel tank. (5-4) • Install the front seat. • Pour engine coolant. (2-17)
