3. Shop for 1 gallon of antifreeze and the correctly replacement radiator hose from your district auto-parts store or dealer. (Radiator hoses are not interchangeable. They come in particular sizes and shapes for your specific motorcar mannequin.)
4. Wait for the engine to refreshing down for at least 20 minutes, before birth any duty on the cooling system.
5. Place a large pan or wide bucket on the ground under the hose to catch the coolant.
6. Use a screwdriver to loosen the hose clamps at both ends of the hose you are replacing.
