RADIATOR CAP TEST

Test

1. Radiator Cap - Test

Engine Cooling System - Testing & Troubleshooting

  1. Wait until the engine is cool, then carefully remove the radiator cap (A). Wet the radiator cap seal with engine coolant, then install it on a commercially available pressure tester (B)
  2. Apply a pressure of 93-123 kPa (0.95-1.25 kgf/cm2, 13.5-17.8 psi)
  3. Check for a drop in pressure
  4. If the pressure drops, replace the radiator cap.
