Kia Cadenza YG 2016-2021 Service Manual / Engine Mechanical System / Cooling System / Thermostat Repair procedures

Removal
   
Removal of the thermostat would have an adverse effect, causing a lowering of cooling efficiency. Do not remove the thermostat, even if the engine tends to overheat.
1.
Drain engine coolant so its level is below thermostat.
(Refer to Cooling System - "Coolant")
2.
Disconnect the ratiator lower hose (A).

(Refer to Cooling System - "Radiator Hose")
3.
Remove the water inlet fitting (A) and the thermostat (B).

Inspection
1.
Immerse thermostat in water heated to over 95°C (203°F), then heat for at least 3 minutes to check valve lift.

   
•
Do not use water below 95°C (203°F).
•
Do not directly heat unit as this will damage thermostat.
2.
Check the valve opening temperature.
Valve opening temperature:
88±2°C (109.4±3.6°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 : 10mm (0.3937in.) or more at 95°C (203°F)
If the valve lift is not as specified, replace the thermostat.
Installation
1.
Place the thermostat in thermostat housing.
(1)
Install the thermostat with the jiggle valve upward.
(2)
Install a new thermostat (B).

2.
Install the water inlet fitting (A).
Tightening torque :
9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
3.
Connect the ratiator lower hose (A).

4.
Install the ratiator upper hose.
(Refer to Cooling System - "Radiator Hose")
5.
Fill with engine coolant.
6.
Start engine and check for leaks.

    Components 1. Water temperature control assembly2. Thermostat3. Water inlet fitting pipe

    Troubleshooting SymptomsPossible CausesRemedyCoolant leakage • From the thermostat gasket Check the mounting bolts • Check the torque of the mounting bolts • Retighten the bolts and check leakage again.
