Hyundai Ioniq: Cooling System / Thermostat. Repair procedures
•
| 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. |
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. |
