ENGINE COOLANT LEAK CHECK

WARNINGWhen pressure testing the cooling system, slowly release cooling system pressure to avoid getting burned by hot coolant.
CAUTIONBe sure to completely clean away any moisture from the places checked. When the tester is taken out, be careful not to spill any coolant. Be careful when installing and removing the tester and when testing not to deform the filler neck of the radiator.
  1. Check that the coolant level is up to the filler neck. Install a radiator tester and apply 160 kPa (23 psi) pressure, and then check for leakage from the radiator hose or connections.
  2. If there is leakage, repair or replace the appropriate part.

RADIATOR CAP OPENING PRESSURE CHECK

Note. Be sure that the cap is clean before testing. Rust or other foreign material on the cap seal will cause an improper reading.

  1. Use a cap adapter to attach the cap to the tester.
  2. Increase the pressure until the indicator of the gauge stops moving. Minimum limit: 83 kPa (12 psi) Standard value: 93 - 123 kPa (14 - 18 psi)
  3. Replace the radiator cap if the reading does not remain at or above the limit.

Required Special Tool

  1. MB991871: LLC Changer
WARNINGWhen removing the radiator cap, use care to avoid contact with hot coolant or steam. Place a shop towel over the cap and turn the cap counterclockwise a little to let the pressure escape through the vinyl tube. After relieving the steam pressure, remove the cap by slowly turning it counterclockwise.

  13. Reinstall the radiator cap.
  14. Start the engine and let it warm up until the thermostat opens.
  15. After repeatedly revving the engine up to 3,000 r/min several times, stop the engine.
  16. Remove the radiator cap after the engine has cooled, and pour in coolant up to the brim. Reinstall the cap. CAUTION: Do not overfill the radiator condenser tank assembly.
  17. Add coolant to the radiator condenser tank assembly between the "FULL" and "LOW" mark if necessary.

WATER PUMP COOLANT LEAK CHECK

If a residue of the coolant draining is found on the drain hole, the vapor hole and the installation surface, check the water pump leakage by following method.

  1. Wipe off the residue of the coolant draining on the water pump. WARNING: Make sure that the coolant is cold when removing the radiator cap.
  2. Remove the radiator cap. CAUTION: Do not pressures 100 kPa (15 psi) or more.
  3. Install the radiator tester and pressures at 100 kPa (15 psi).
  4. Hold the pressurized state for 20 minutes, and check that the water leakage from the drain hole, the vapor hole or the installation surface of the water pump.
  5. Remove the radiator tester, and install the radiator cap.
  6. Warm up the engine, let it idle for 20 minutes and stop it.
  7. After stopping the engine, and check that the water leakage from the drain hole, the vapor hole or the installation surface of the water pump.
  8. If the water leakage is found in step 4 or 7 , replace the water pump. (Refer to «REMOVAL AND INSTALLATION < 2.4L ENGINE >»(ref-394946-S05972410222011040900000) < 2.4L Engine >, «REMOVAL AND INSTALLATION < 3.0L ENGINE >»(ref-394946-S24535443132011040900000) < 3.0L Engine >).
