Kia Carens: Cooling System / Thermostat Repair procedures
Disassembly of the thermostat would have an adverse effect, causing
a lowering of cooling efficiency.
|
1. |
Drain engine coolant so that its level would be under the thermostat
height.
|
2. |
Remove the radiator lower hose.
(Refer to Cooling System - "Radiator Hose")
|
3. |
Remove the water inlet fitting (A) and thermostat (B).

|
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:
82±1.5°C (179.6±2.7°F)
Full opening temperature: 95°C (203°F)
|
If the valve opening temperature is not as specified, replace the thermostat.
|
3. |
Check the valve lift.
Valve lift : 8mm(0.3in) or more at 95°C (203°F)
|
If the valve lift is not as specified, replace the thermostat.
|
1. |
Place the thermostat in the block.
Install the thermostat (B) with the jiggle valve upward.
|
2. |
Install the water inlet fitting (A).
Tightening torque :
18.6 ~ 23.5N.m (1.9 ~ 2.4kgf.m, 13.7 ~ 17.4lb-ft)
|

|
3. |
Fill with engine coolant.
|
4. |
Start engine and check for leaks.
