Engine Mechanical: Maintenance Kia Sorento I рестайлинг

ENGINE COOLANT REFILLING AND BLEEDING

1. Make sure the engine and radiator are cool to the touch.
2. Remove 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 fluid mixture with coolant and water (4:6) 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 50% minimum. Coolant concentrations less than 50% 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.
7. Start the engine and run coolant circulates. When the cooling fan operates and coolant circulates, refill coolant through the radiator cap.
8. Repeat 7 until the cooling fan 3-5 times and bleed air sufficiently out of the cooling system.
9. Install the radiator cap and fill the reservoir tank to the "MAX" line with coolant.
10. Run the vehicle under idle until the cooling fan operates 2-3 times.
11. Stop the engine and wait coolant gets cool.
12. Repeat 6 to 11 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.

Scheme 153

1. Remove the radiator cap, wet it's seal with engine coolant, then install it to pressure tester.
2. Apply a pressure of 93-123 kPa (0.95-1.25 kgf/cm 2 , 14-19 psi)
3. Check for a drop in pressure.
4. If the pressure drops, replace the cap.

Scheme 154

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 93-123 kPa (0.95-1.25 kgf/cm 2 14-18 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 155

Scheme 156

1. Drain the engine coolant. WARNING: System is under high pressure when the engine is hot. To avoid danger of releasing scalding engine coolant, remove the cap only when the engine is cool.
2. Remove drive belt (A).
3. Remove the 4 bolts and pump pulley (A).
4. Remove the cooling fan shroud.
5. Remove the water pump (A) and gasket.

2. Remove the engine cover (A).
3. Remove the under cover (A).
4. Remove the radiator grille upper cover (A).
5. Disconnect the radiator upper hose (A) and lower hose (B) and the automatic transaxle fluid cooler hoses (C).
6. Remove the radiator from the condenser by removing bolts. Refer to Condenser in «HEATING, VENTILATION AND AIR CONDITIONING»(ref-278799) .
7. Remove the cooling fan shroud (A) after disconnecting cooling fan harness connector (B) and loosening the mounting bolts (C).
8. Remove the radiator assembly.

5. Disconnect the RH/LH cooling pipes (A, B).
6. Disconnect WTS connector.
7. Disconnect heater hose, water vent hose and water hose from water temperature control assembly.
8. Remove the fuel pipe (A).
9. Remove water temperature control assembly (A).
