ENGINE COOLANT LEAKAGE INSPECTION [MZR-CD (RF Turbo)]

id0112f1800500

  Warning

  • Never remove the cooling system cap or loosen the radiator drain plug while the engine is running, or when the engine and radiator are hot. Scalding engine coolant and steam may shoot out and cause serious injury. It may also damage the engine and cooling system.
  • Turn off the engine and wait until it has cooled. Even then, be very careful when removing the cap. Wrap a thick cloth around it and slowly turn it counterclockwise to the first stop. Step back while the pressure escapes.
  • When you are sure all the pressure is gone, press down on the cap using the cloth, turn it, and remove it.

1. Inspect the engine coolant level. (See ENGINE COOLANT LEVEL INSPECTION [MZR-CD (RF Turbo)].)

2. Remove the cooling system cap.

3. Clean the mounting surface of the cooling system cap and the upper radiator hose.

4. Install the SST to the engine coolant filler port.

5. Apply specified pressure to the radiator.

  Caution

  • Applying more than 122.6 kPa {1.25 kgf/cm2, 17.8 psi} can damage the hoses, fittings, and other components, and cause leaks.

Pressure

  122.6 kPa {1.25 kgf/cm2, 17.8 psi}

6. Verify that the pressure is held.

  • If not as specified, inspect the system for engine coolant leakage.

  - If the engine coolant leaks from the upper hose attachment part, replace the upper hose and the clamp.
  - If the engine coolant leaks from the main body of the radiator (caulked part), replace the radiator.
