Engine Cooling System: Removal & Installation Kia Sedona II рестайлинг

Replacement And Air Bleeding

Note. When pouring engine coolant, be sure to shut the relay box lid and not to let coolant spill on the electrical parts or the paint. If any coolant spills, rinse it off immediately.

1. Make sure the engine and radiator are cool to the touch.
2. Remove the radiator cap.
3. Loosen the drain plug, and drain the coolant.
4. Tighten the radiator drain plug securely.
5. Remove, drain and reinstall the reservoir. Fill the tank halfway to the MAX mark with water, then up to the MAX mark with antifreeze.
6. Fill the radiator with water through the radiator cap and tighten the cap. NOTE: To most effectively bleed the air, pour the water slowly and press on the upper/lower radiator hoses.
7. Start the engine and allow to come to normal operating temperature. Wait for the cooling fans to turn on several times. Accelerate the engine to aid in purging trapped air. Shut engine off.
8. Wait until the engine is cool.
9. Repeat steps 1 - 8 until the drained water runs clear.
10. Fill fluid mixture with coolant and water (55~60%) (except for North America, Europe and China : 45~50%) slowly through the radiator cap. Push the upper/lower hoses of the radiator so as bleed air easily. NOTE: Use only genuine antifreeze/coolant. For best corrosion protection, the coolant concentration must be maintained year-round at 55% (except for North America, Europe and China : 45%) minimum. Coolant concentrations less than 55% (except for North America, Europe and China : 45%) may not provide sufficient protection against corrosion or freezing. Coolant concentrations greater then 60% will impair cooling efficiency and are not recommended. CAUTION: Do not mix different brands of antifreeze/coolants. Do not use additional rust inhibitors or antirust products; they may not be compatible with the coolant.
11. Start the engine and run coolant circulates.
12. When the cooling fan operates and coolant circulates, refill coolant through the radiator cap.
13. Repeat step 11 until the cooling fan 3 ~ 5 times and bleed air sufficiently out of the cooling system.
14. Install the radiator cap and fill the reservoir tank to the "MAX" line with coolant.
15. Run the vehicle under idle until the cooling fan operates 2 ~ 3 times.
16. Stop the engine and wait coolant gets cool.
17. Repeat 10 to 15 until the coolant level doesn't fall any more, bleed air out of the cooling system.

Note. As it is to bleed air out to the cooling system and refill coolant when coolant gets cool completely, recheck the coolant level in the reservoir tank for 2 ~ 3 days after replacing coolant.

1. Disconnect the battery negative terminal (A). Tightening torque: 4.0 ~ 6.0 N.m (0.4 ~ 0.6 kgf.m, 3.0 ~ 4.4 lb-ft)
2. Remove the radiator grille upper cover (B).
3. Remove the air cleaner assembly.
4. Remove the battery and battery tray.
5. Remove the under cover.
6. Loosen the drain plug (A), and drain the coolant. Remove the radiator cap to speed draining. WARNING: Never remove the radiator cap when the engine is hot. Serious scalding could be caused by hot fluid under high pressure escaping from the radiator.
7. Remove the radiator upper hose (A), lower hose (B).
8. Disconnect the ATF cooler hose (A/T only). Refer to «REMOVAL»(ref-584179-S23979579372013110100000) .
9. Disconnect the fan motor connector (A).
10. Remove the radiator support upper member assembly (A) for convenience sake. Tightening torque: 8.8 ~ 10.8 N.m (0.9 ~ 1.1 kgf.m, 6.5 ~ 7.9 lb-ft) NOTE: The bottom side bolt (A) which can be seen after removing the under cover should be loosened for removal of the radiator support upper member assembly.
11. Disconnect the over flow hose from the radiator.
12. Disconnect the A/C pressure pipe (A) from the radiator assembly (B).
13. Separate the condenser (A) from the radiator assembly (B) by removing the bolts (C). Tightening torque: 8.8 ~ 10.8 N.m (0.9 ~ 1.1 kgf.m, 6.5 ~ 7.9 lb-ft)
14. Remove the radiator bracket.
15. Remove the radiator assembly.
16. Remove the radiator cooling fan (A). Tightening torque: 8.8 ~ 10.8 N.m (0.9 ~ 1.1 kgf.m, 6.5 ~ 7.9 lb-ft)
17. Installation is in the reverse order of removal.
18. Fill the radiator with coolant and check for leaks.

Note. Bleed air from the cooling system. Start engine and let it run until it warms up. (Until the radiator fan operates 3 or 4 times.) Turn off engine and let it cool down. Check the coolant level and add coolant if needed. This will allow trapped air to be removed from the cooling system. Put the radiator cap on tightly, then run engine again and check for leaks.

Scheme 13

1. Remove the radiator cap, wet its seal with engine coolant, and then install it on a pressure tester.
2. Apply a pressure of 93.16 ~ 122.58 kPa (0.95 ~ 1.25kg/cm 2 , 13.51 ~ 17.78 psi).
3. Check for a drop in pressure.
4. If the pressure drops, replace the cap.

Scheme 14

1. Wait until engine is cool, then carefully remove the radiator cap and fill the radiator with engine coolant, then install it on the pressure tester.
2. Apply a pressure tester to the radiator and apply a pressure of 93.16 ~ 122.58 kPa (0.95 ~ 1.25 kg/cm 2 , 13.51 ~ 17.78 psi).
3. Inspect for engine coolant leaks and a drop in pressure.
4. Remove the tester and reinstall the radiator cap.

Note. Check for engine oil in the coolant and/or coolant in the engine oil.

Scheme 17

1. Loosen the drain plug, and drain the engine coolant. CAUTION: Never remove the radiator cap when the engine is hot. Serious scalding could be caused by hot fluid under high pressure escaping from the radiator.
2. To release the tension, turn the drive belt tensioner counterclockwise then remove the drive belt (A).
3. Remove the water pump pulley (A).
4. Remove the water pump (A) and gasket (B).

Removal

Note. 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.
2. Remove the water inlet fitting (A) and the thermostat (B).

1. Place the thermostat in thermostat housing. Install the thermostat with the jiggle valve upward. Install a new thermostat (B).
2. Install the water inlet fitting (A). Tightening torque: 16.7 ~ 19.6 N.m (1.7 ~ 2.0 kgf.m, 12.3 ~ 14.5 lb-ft)
3. Fill with engine coolant.
4. Start engine and check for leaks.
