Kia Carnival (2007 year). Manual — part 422

8. Start the engine and let it run until it warms up. ( until the radiator fan operates 3 or 4 times.)

9. Turn off the engine. Check the level in the radiator, add coolant if needed. This will allow trapped air to be removed

from the cooling system.

10. Put the radiator cap on tightly, then run the engine again and check for leaks.

RADIATOR CAP TESTING

1. Remove the radiator cap, wet its seal with engine coolant, then install it no pressure tester.

2. Apply a pressure of 93.16 ~ 122.58kpa (0.95 ~ 1.25kg/cm², 13.51 ~ 17.78psi).

3. Check for a drop in pressure.

4. If the pressure drops, replace the cap.

RADIATOR LEAKGE TEST

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 ~ 122.58kpa (0.95 ~ 1.25kg/cm², 13.51 ~

17.78psi).

3. Inspect for engine coolant leaks and a drop in pressure.

4. Remove the tester and reinstall the radiator cap.

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

REMOVAL

WATER PUMP

1. Drain the engine coolant.

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 the drive belts.

3. Remove the timing belt.

4. Remove the water pump.

THRMOSTAT

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.

2. Remove the thermostat housing, gasket and thermostat.

RADIATOR

1. Drain the engine coolant.

2. Remove the radiator upper cover(A).

3. Remove the radiator upper hose(A).

4. Remove the radiator lower hose(A).

5. Remove the intercooler hose(A,C), pipe(B).
