2007 KIA CARNIVAL coolant temperature

2007 > 2.7L V6 GASOLINE >
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 drive belt(A).
3.Remove the timing belt.
4. Remove the water pump(A) and gasket(B).
WATER TEMPERATURE CONTROL ASSEMBLY
1.Drain the engine coolant.
2. Remove the air cleaner assembly.
3. Disconnect the radiator upper and lower hose(A, B).

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

THERMOSTAT
1.Immerse the thermostat in water and gradually heat water.
2.Check the valve opening temperature.
Valve opening temperature : 82°C (177°F)
Full opening temperature : 95°C (205°F)
If the valve opening temperature is not as specified, replace the thermostat.
3. Check the valve lift.
Valve lift : Min. 10mm (0.4in.) at 95°C (205°F)
If the valve lift is not as specified, replace the thermostat.
ENGINE COOLANT REFILLING AND BLEEDING
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.
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. Open the radiator cap.
3. Loosen the drain plug, and drain the coolant.
4. Tighten the radiator drain plug securely.
5. Remove, drain and clean the reservoir tank.
6. Fill water slowly through the radiator cap. Push the upper/lower hoses of the radiator so as to bleed air easily.
7. Warm the engine until the cooling fan operates 2~3 times.
Accelerate the engine 2~3 times without load.
8. Wait until the engine is cold.
9. Repeat the steps 1~8 until the water drained is clean.
10. Fill fluid mixture with coolant and water(4 : 6) slowly through the radiator cap. Push the upper/lower hoses of the
radiator so as to bleed air easily.
11. Start the engine and run so coolant circulates.
When the cooling fan operates and coolant circulates, refill coolant through the radiator cap.
12. Repeat 11 until the cooling fan cycles 3 ~ 5 times and bleed air sufficiently out of the cooling system.

(7)Disconnect the bank 2 CMP sensor connector(A) and the ECT(Engine Coolant Temperature) sensor
connector(B).
(8)Disconnect the bank 2 front/rear O2 sensor connectors(A,B) and the CKP sensor connector(C).
(9)Disconnect the bank 1 CMP sensor connector(A).
4.Remove the PCV(Pulge Control Valve) hose(A).

INSPECTION
1.Disconnect the vacuum hose from the throttle body, and connect a vacuum pump to the vacuum hose.
2. Check the following points when the engine is cold [engine coolant temperature 60°C(140°F) or below] and when it
is warm [engine coolant temperature 80°C(176°F) or higher].
WHEN ENGINE IS COLD
Engine operating condition Applied vacuumResult
Idling 50 kPa
(7.3 psi) Vacuum is held

WHEN ENGINE IS WARM Engine operating condition Applied vacuumResult
Idling 50 kPa
(7.3 psi) Vacuum is held
Within 3 minutes after engine start at 3,000
rpm Try to apply vacuum
Vacuum is released
After 3 minutes have passed after engine
start at 3,000 rpm 50 kPa
(7.3 psi) Vacuum will be held momentarily,
after which, it will be released
