ENGINE COOLANT REFILLING AND BLEEDING

WARNINGNever remove the radiator cap when the engine is hot. Serious scalding could be caused by hot fluid under high pressure escaping from the radiator.
CAUTIONWhen 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 radiator cap.
  3. Loosen the drain plug, and drain the coolant.
  4. Tighten the radiator drain plug securely.
  5. Remove, drain and reinstall the reservoir. Fill the tank halfway to the MAX mark with water, then up to the MAX mark with antifreeze.
  6. Fill fluid mixture with coolant and water (4:6) slowly through the radiator cap. Push the upper/lower hoses of the radiator so as bleed air easily. NOTE: Use only genuine antifreeze/coolant. For best corrosion protection, the coolant concentration must be maintained year-round at 50% minimum. Coolant concentrations less than 50% may not provide sufficient protection against corrosion or freezing. Coolant concentrations greater then 60% will impair cooling efficiency and are not recommended. CAUTION: Do not mix different brands of antifreeze/coolants. Do not use additional rust inhibitors or antirust products; they may not be compatible with the coolant.
  7. Start the engine and run coolant circulates. When the cooling fan operates and coolant circulates, refill coolant through the radiator cap.
  8. Repeat 7 until the cooling fan 3 ~ 5 times and bleed air sufficiently out of the cooling system.
  9. Install the radiator cap and fill the reservoir tank to the "MAX" line with coolant.
  10. Run the vehicle under idle until the cooling fan operates 2~3 times.
  11. Stop the engine and wait coolant gets cool.
  12. Repeat 6 to 11 until the coolant level doesn't fall any more, bleed air out of the cooling system.

Note. As it is to bleed air out to the cooling system and refill coolant when coolant gets cool completely, recheck the coolant level in the reservoir tank for 2 ~ 3 days after replacing coolant.

Scheme 328

Scheme 328: CAP TESTING
  1. Remove the radiator cap, wet its seal with engine coolant, then install it no pressure tester.
  2. Apply a pressure of 93 ~ 123 kPa (0.95 ~ 1.25 kgf/cm 2 , 14 ~ 19 psi)
  3. Check for a drop in pressure.
  4. If the pressure drops, replace the cap.

Scheme 329

Scheme 329: TESTING
  1. Wait until engine is cool, then carefully remove the radiator cap and fill the radiator with engine coolant, then install it on the pressure tester.
  2. Apply a pressure tester to the radiator and apply a pressure of 93 ~ 123 kPa (0.95 ~ 1.25 kgf/cm 2 14 ~18 psi).
  3. Inspect for engine coolant leaks and a drop in pressure.
  4. Remove the tester and reinstall the radiator cap.

Note. Check for engine oil in the coolant and/or coolant in the engine oil.

Scheme 331

Scheme 331
  1. Drain the engine coolant. WARNING: 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 4 bolts and pump pulley (A).
  4. Remove the water pump (A) and gasket.

Scheme 332

Scheme 332
  1. Drain the engine coolant.
  2. Remove air cleaner assembly. (See «REMOVAL»(ref-286594-S40067863922008060300000) )
  3. Disconnect radiator upper and lower hose (A).
  4. Disconnect WTS connector. (See «REMOVAL»(ref-286594-S40067863922008060300000) )
  5. Disconnect heater hose, water vent hose and water hose from water temperature control assembly.
  6. Remove wiring protector.
  7. Remove water temperature control assembly (A).
