Checking the cooling system for leaks (Hyundai Accent X3)

1. Wait until the radiator cools down (below 38°C). Loosen the radiator cap.

2. Make sure the coolant level is at the filler neck.

3. Install a radiator cap tester on the filler neck and create a pressure of 139.3 kPa.



While maintaining pressure for two minutes, check for leaks from the radiator, as well as through hoses and connections.

Warning: The coolant in the radiator may be very hot. Do not open the system while it is hot, otherwise boiling liquid ejected from the system may cause injury to a person. Allow to cool before servicing.

4. If a leak is detected, repair or replace the defective part.
