Replacing a leaking radiator hose can be inconsiderable and considerably painless on most cars. Turn off the engine as soon as you suspect a leak, to prevent the engine from overheating.2. Fix upon which radiator hose is leaking and true where the leak is future from by looking for wetness.
Research that both ends of the leaking hose are easily accessed before attempting this repair, by reason of on some cars the hoses are tightly tucked outside and this assignment might be higher quality left to a acknowledged.
Instructions
1.3. 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.
7. Remove the radiator hose by twisting and pulling where it connects to the radiator and engine. If the hose won't budge, use a utility knife to cut it off the fittings.

9. Put the new radiator hose on. Spray the inside of the hose ends with WD-40 if the hose is hard to get on. Tighten the hose clamps.
10. Refill the radiator and the coolant reservoir with a 50-50 mixture of water and antifreeze.
11. "Burp the cooling system" by running the engine with the radiator cap off until the engine warms up. Keep the engine running until both the upper and lower radiator hoses feel warm (this indicates that the thermostat is open and the coolant is flowing through the entire system). Burping the cooling system allows any air bubbles to escape. Add coolant to the radiator as needed.
12. Look for leaks. Inspect around the hose clamps for dampness. Tighten the hose clamps if there is any wetness.
13. Put the radiator cap back on.
14. Check the coolant level after driving, to ensure there are no leaks.
