INSPECT FINS FOR BLOCKAGE

If fins are clogged, wash them with water or a steam cleaner and dry with compressed air.

Note. If the distance between the steam cleaner and the core is too close, there is a possibility of damaging the fin, so keep the following injection distance. INJECTION PRESSURE DISTANCE Injection Pressure Injection Distance 2,942 - 4,903 kpa (30 - 50 kg/cm 2 . 427-711 psi) 300 mm (11.811 in) 4,903 - 7,845 kpa (50 - 80 kg/cm 2 . 711-1,138 psi) 500 mm (19.685 in) If the fins are bent, straighten them with a screwdriver or pliers. Never apply water directly onto the electronic components.

  1. REMOVE RADIATOR CAP CAUTION: To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator are still hot, as fluid and steam can be blown out under pressure.
  2. INSPECT RADIATOR CAP NOTE: If the radiator cap has contaminations, always rinse it with water. Before using a radiator cap tester, wet the relief valve and pressure valve with engine coolant or water. When performing steps (a) and (b) below, keep the tester at an angle of over 30° above the horizontal. Using a radiator cap tester, slowly pump the tester and check that air is coming from the vacuum valve. Pump speed: 1 push/(3 seconds or more) NOTE: Push the pump at a constant speed. If air is not coming from the vacuum valve, replace the radiator cap. Pump the radiator cap tester, and measure the relief valve opening pressure. Pump speed: 1 push within 1 second NOTE: This pump speed is for the first pump only (in order to close the vacuum valve). After this, the pump speed can be reduced. Standard opening pressure: 93-123 kPa (0.95 - 1.25 kgf/cm 2 , 13.5 - 17.8 psi) Minimum opening pressure: 78 kPa (0.8 kgf/cm 2 , 11.4 psi) HINT: Use the tester's maximum reading as the opening pressure. If the opening pressure is less than minimum, replace the radiator cap.
  3. INSPECT COOLING SYSTEM FOR LEAKS Fill the radiator with coolant and attach a radiator cap tester. Warm up the engine. Pump it to 118 kPa (1.2 kgf/cm 2 , 17.1 psi), and check that the pressure does not drop. If the pressure drops, check the hoses, radiator or water pump for leaks. If no external leaks are found, check the heater core, cylinder block and head.
  4. REINSTALL RADIATOR CAP
