2007 KIA CARNIVAL coolant level

4.Disconnect the ECT(Engine Coolant Temperature) sensor connector.
5. Remove the coolant hose related to the heater hoses and the ECT(Engine Coolant Temperature) system.
6. Remove wiring protector.
7. Remove water temperature control assembly(A) and the gaskets(B).
8.Remove the water pipe(A).
THERMOSTAT
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 coolant inlet pitting(A) and the thermostat(B).

Clean the contacting face before assembling.
2. Install the timing belt.
3. Install drive belt(A).
4.Fill with engine coolant.
5. Start engine and check for leaks.
6. Recheck engine coolant level.
WATER TEMPERATURE CONTROL ASSEMBLY
1.Install the water pipe(A).
Tightening torque
16.7 ~ 19.6Nm (1.7 ~ 2.0kgf.m, 12.3 ~ 14.5lb- ft)
2.Install the water temperature control assembly(A) with a new gasket(B).
Tightening torque

29.4 ~ 41.2Nm(3.0 ~ 4.2kgf.m, 21.7 ~ 30.4lb- ft
Use new O - rings and wet them with water or coolant when reassembling.
3. Install the wiring protector.
4. Connect the heater hose and ECT hose.
5. Connect the ECT sensor connector.
6. Connect the radiator upper and the lower hose(A).
7.Install the air cleaner assembly.
8. Fill with engine coolant.
9. Start engine and check for leaks.
10. Recheck engine coolant level.
THERMOSTAT
1.Place thermostat(B) in coolant inlet pitting(A).
Install the thermostat with the jiggle valve upward.

7.Install the radiator upper(A) and lower hoses(B).
8.Install the radiator support upper member assembly(A).
9.Install the radiator grille upper cover(A).
10. Fill with engine coolant.
11. Start engine and check for leaks.
12. Recheck engine coolant level.
INSPECTION
WATER PUMP
1. Check each part for cracks, damage or wear, and replace the coolant pump assembly if necessary.
2. Check the bearing for damage, abnormal noise and sluggish rotation, and replace the coolant pump assembly if
necessary.
3. Check for coolant leakage. If coolant leaks from hole, the seal is defective. Replace the coolant pump assembly.
A small amount of "weeping" from the bleed hole is normal.

13.Install the radiator cap and fill the reservoir tank to the "MAX"(or "F") line with coolant.
14. Run the vehicle under idle until the cooling fan operates 2 ~ 3 times.
15. Stop the engine and wait until coolant gets cool.
16. Repeat 10 to 15 until the coolant level doesn't fall any more, bleeding air out of the cooling system.
Check the coolant level again in the reservoir tank for 2 ~ 3 days after replacing coolant.
CAP TESTING
1.Remove the radiator cap, wet its seal with engine coolant, and install it to a pressure tester.
2.Apply a pressure of 93 ~ 123kPa (0.95 ~ 1.25kgf/cm², 14 ~ 19psi).
3. Check for a drop in pressure.
4. If the pressure drops, replace the cap.

Always use a new O - ring.
8. Install the timing belt, the generator and the front muffler.
9. Install the front right side cover and the wheel and tire.
10. Fill with engine coolant.
11. Start engine and check for leaks.
12. Recheck engine coolant level.
INSPECTION
1.Check engine oil quality.
Check the oil for deterioration, entry of water, discoloring or thinning.
If the quality is visibly poor, replace oil.
2. Check the engine oil level.
After warning up the engine, make the engine stand still for five minutes or more. The oil level should be between
the 'L' and 'F' marks on the dipstick, then.
If low, check for leakage and add oil up to the "F" mark.
Do not fill with engine oil above the "F" mark.
