  • The engine should be switched off and the product used only with a cold engine.
  • Locate the coolant filler cap on your radiator (refer to your vehicle's user manual if necessary).
  • If your vehicle does not have a radiator, pour the solution directly into the expansion tank.
  • Open the filler cap and add the NoLeaky® solution to the coolant.
  • Once the radiator is full, start the engine and allow it to warm up thoroughly for around 30 minutes, then switch it off and let it cool completely.
  • Once the engine has cooled, top up the coolant.
  • You can then use your vehicle.
