The radiator is a crucial part of any car's engine because it ensures the proper functioning of the cooling system. It is essential to keep it clean.

The first step is to drain it completely by opening the drain valve. Clean the metal fins that allow air to pass through, located in front of and behind the radiator.

Replace the hoses coming from the radiator if they are worn, as they may not be able to ensure the proper flow of coolant. After draining all the fluid, rinse the radiator by opening the drain valve to let out the water.

Once finished, you can add new coolant, start the vehicle, and bleed the radiator with the cap open.
