Hyundai Santa Fe (TM): Cooling System
Coolant. Repair procedures
Refilling And Bleeding |
|
|
|
1. |
Make sure the engine and radiator are cool to the touch.
|
2. |
Remove reservoir tank cap (A).
|
3. |
Loosen the drain plug (A), and drain the coolant.
|
4. |
Tighten the radiator drain plug securely.
|
5. |
After draining engine coolant in the reservoir tank, clean the tank.
|
6. |
Fill the radiator with water through the reservoir tank cap and tighten
the cap.
|
7. |
Start the engine and allow to come to normal operating temperature.
Wait for the cooling fans to turn on several times. Accelerate the engine
to aid in purging trapped air. Shut engine off.
|
8. |
Wait until the engine is cool.
|
9. |
Repeat steps 1 to 8 until the drained water runs clear.
|
10. |
Fill fluid mixture with coolant and water(5:5) (Tropical region – 4:6)
slowly through the radiator cap. Push the upper/lower hoses of the radiator
so as bleed air easily.
|
11. |
Start the engine and run until coolant circulates.
When the cooling fan operates and coolant circulates, refill coolant
through the radiator cap.
|
12. |
Repeat 11 until the cooling fan 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 coolant gets cool.
|
16. |
Repeat 10 to 15 until the coolant level doesn't fall any more, bleed
air out of the cooling system.
|
