Overview:
This project will show you how to replace a radiator hose. A leaking radiator hose can mean an overheated engine and a roadside breakdown. Head off trouble by replacing your radiator hose at the first sign of a leak. Before tackling this repair your self, make sure that both ends of the hose are easily accessible. If one end is tightly tucked away, you may want to let a professional handle the job.
Materials:
new radiator hose, antifreeze, WD-40 silicone spray
Tools You'll Need:
slotted screwdriver, quick change utility knife, funnel
Before You Begin:
Turn off your car's engine as soon as you suspect a leak, to prevent the engine from overheating. Determine where the radiator hose is leaking by checking for wetness. If the car has been running, wait about 20 minutes for the engine to cool down before proceeding. DO NOT remove the radiator cap or hose until the engine has cooled. The coolant could spray out and burn you.
Barbara's Tips:
Radiator hoses are not interchangeable. Make sure you purchase the correct replacement for the make and model of your car.

Step 1: Set Up
Place the bucket or pan on the ground under the hose to catch the coolant. Be sure to dispose of coolant properly - bring it to a repair shop or parts store for recycling. Do not pour it down the sink or into the gutter. Coolant is also both tasty and toxic to dogs. Keep your pets well away while completing this job. Using the screwdriver, loosen the hose clamps at both ends of the hose and remove the radiator hose by twisting and pulling where it connects to the radiator and engine. If the hose is stuck tight, use the utility knife to cut it off the fittings.
Step 2: Prep the New Hose
Remove the hose clamps from the old hose and put them on the new hose. Attach the new hose to the radiator and engine. Spray the inside of the ends with WD-40 if you are having a hard time sliding the new hose on. When the new hose is in place, tighten the clamps.
Step 3: Feed and "Burp"
Refill the radiator and the coolant reservoir with a 50-50 mixture of water and coolant. "Burp" the system by running the engine with the radiator cap off until the engine warms up. Keep the engine running until both ends of the radiator hose feel warm. Add coolant as needed.
Step 4: Check Your Work
Check for leaks and inspect around the hose clamps for dampness. Tighten the hose clamps if you feel any wetness. Put the radiator cap back on and recheck the coolant level once more after driving to make sure there are no leaks. Your engine's running smooth and cool, and you did it yourself!
