System Inspection

WARNING: This page is about a different variant/trim than selected.

■ Coolant Level Inspection

Check the cooling system coolant level.
Is the coolant in the reservoir at the proper level?
YES
- Go to next step as below.
NO
- Repair or add engine coolant as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

■ Thermostat Inspection

Check if the thermostat bypass valve is stuck in the open position or if the correct type of thermostat was installed. Replace thermostat as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check the valve opening temperature of the thermostat.
Specification (Valve opening temperature): 80~84°C(176~183°F)
If the opening temperature is not as specified, Replace thermostat as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
If OK, go to next step as below.

■ ECT Sensor Inspection

Measure resistance between terminals 1 and 3 of the sensor connector (Component side)

TEMPERATURE RESISTANCE SPECIFICATION

Temp.(°C)	Resistance(kΩ)	Temp.(°C)	Resistance(kΩ)
-20	14.1 ~ 16.8	40	Approx. 1.2
0	Approx. 5.8	60	Approx. 0.6
20	2.3~2.6	80	Approx. 0.3

Is resistance within the specification?
YES
- Go to next step as below.
NO
- Check ECTS for contamination, deterioration, or damage. Substitute with a known-good ECTS and check for proper operation. If the problem is corrected, replace ECTS and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
