coolant reservoir KIA CARNIVAL 2007 Workshop Manual

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.

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.
