Inspection |
1. |
Check radiator hoses for the following
|
1. |
Check the coolant level in the coolant reservoir. Make sure it is between
the "F" mark and "L" mark.
|
2. |
If the coolant level in the coolant reservoir is at or below the "L"
mark, add coolant to bring it between the "L" and "F" marks, then inspect
the cooling system for leaks.
|
1. |
Remove the pressure cap.
|
2. |
Check if there are any excessive deposits of rust or scale around the
pressure cap sub-assembly and radiator filler hole. Also, the coolant
should be free of oil.
If excessively dirty, clean the coolant passage and replace the coolant.
|
3. |
Install the pressure cap.
|
Replacement And Air 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. |
Remove the pressure cap (A).
|
3. |
Remove the engine room under cover.
(Refer to Engine Mechanical System - "Engine Room Under Cover")
|
4. |
Loosen the drain plug (A), and drain the coolant.
|
5. |
Tighten the radiator drain plug securely.
|
6. |
Remove, drain and reinstall the reservoir. Fill the tank halfway to
the MAX mark with water, then up to the MAX mark with antifreeze.
|
7. |
Fill the radiator with water through the pressure cap and tighten the
cap.
|
8. |
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.
|
9. |
Wait until the engine is cool.
|
10. |
Repeat steps 1 to 8 until the drained water runs clear.
|
11. |
Fill fluid mixture of coolant and water (45 - 60%) (except for North
America, Europe and China : 45 - 50%) slowly through the radiator cap.
Push the upper / lower hoses of the radiator so as to bleed air easily.
|
12. |
Start the engine and let coolant to circulate.
|
13. |
When the cooling fan operates and coolant circulates, refill coolant
through the radiator cap.
|
14. |
Repeat step 11 until the cooling fan operates 3-5 times and bleed air
sufficiently out of the cooling system.
|
15. |
Install the pressure cap and fill the reservoir tank to the "MAX"(or
"F") line (A) with coolant.
|
16. |
Run the vehicle under idle until the cooling fan operates 2 - 3 times.
|
17. |
Stop the engine and wait for coolant to cool down.
|
18. |
Repeat 10 to 15 to bleed air out of the cooling system until the coolant
level doesn't fall any more.
