Hyundai Ioniq (AE) 2017-2024 Service Manual / Engine Mechanical System / Cooling System / Thermostat. Repair procedures

Removal and Installation
   
Disassembly of the thermostat would have an adverse effect, causing a lowering of cooling efficiency.
1.
Drain the engine coolant so its level is below thermostat.
(Refer to Cooling System - "Coolant")
2.
Disconnect the radiator lower hose (A).

   
When installing radiator hoses, install as shown in illustrations.

   
When the radiator lower hose detached, remove the holder clip (A) and then disconnect the quick connector.

3.
Remove the water inlet fitting (A).
Tightening torque :
18.6 - 23.5 N.m (1.9 - 2.4 kgf.m, 13.7 - 17.4 lb-ft)

4.
Remove the thermostat (A).

   
Install the thermostat with the jiggle valve upward.
5.
Install in the reverse order of removal.
6.
Fill the radiator with coolant and check for leaks.
(Refer to Cooling System - "Coolant")
7.
Start engine and check for leaks.
8.
Recheck the coolant level.
Inspection
1.
Immerse the thermostat in water and gradually heat the water.

2.
Check the valve opening temperature.
Valve opening temperature : 88 ± 1.5°C (190.4 ± 2.7°F)
Full opening temperature : 100°C (212°F)
If the valve opening temperature is not as specified, replace the thermostat.
3.
Check the valve lift.
Valve lift : 8 mm (0.3 in) or more at 100°C (212°F)
If the valve lift is not as specified, replace the thermostat.

    DescriptionContinuous Variable Valve Timing (CVVT) system advances or retards the valve timing of the intake and exhaust valve in accordance with the ECM control signal which is calculated by the engine speed and load.By controlling CVVT, the valve over-lap or under-lap occurs, which makes better fuel economy and reduces exhaust gases (NOx, HC) and improves engine performance through reduction of pumping loss, internal EGR effect, improvement of combustion stability, improvement of volumetric efficiency, and increase of expansion work...

    Tilt Steering / Telescope Steering

    Adjust the steering wheel so it points toward your chest, not toward your face. Make sure you can see the instrument cluster warning lights and gauges. After adjusting, push the steering wheel both up and down to be certain it is locked in position. Always adjust the position of the steering wheel before driving.

    WARNING

    NEVER adjust the steering wheel while driving. This may cause loss of vehicle control resulting in an accident.
