Radiator Test

  1. Wait until the engine is cool, then carefully remove the radiator cap and fill the radiator with engine coolant to the top of the filler neck.
  2. Attach the commercially available pressure tester (A) to the radiator and apply a pressure of 93-123 kPa (0.95-1.25 kgf/cm2, 14-18 psi).
