Things You'll Need:
- Pliers
- Socket set
- Wrenches
-
Step 1
Find the hoses you need from an auto-part supplier listed at AutoGuide.net (see Resources below).
-
Step 2
Ensure that your car's engine is completely cool before you begin to replace your coolant system hoses.
-
Step 3
Find your car's battery, and disconnect it. You're going to be working deeper in the engine, and disconnecting your car's battery ensures that you will not receive an accidental shock if you touch the wrong thing.
-
Step 4
Disconnect or remove any engine parts that are in your way. If your car is a rear-wheel-drive model, your engine will be oriented front to back, and there shouldn't be much in your way. However, if you have a front-wheel-drive car, you might have to clear the alternator, its mounting brackets, the fan, the fan shroud and the pulley out of your way.
-
Step 5
Access your car's coolant system. The coolant system hoses are attached to the water pump.
-
Step 6
Use wrenches, pliers and a socket set, as needed, to loosen the nuts and seals that attach the hoses to the water pump.
-
Step 7
Slide the water pump hoses off once they've been loosened. You should be able to pull them right out with no resistance. Discard them.
-
Step 8
Replace the old water pump hoses with new ones, sliding them into the same position the old ones occupied and fastening them using sealers, nuts and bolts.
-
Step 9
Replace any other engine parts you had to remove in order to access the coolant system.
-
Step 10
Reactivate your car battery and close the hood.
-
Step 11
Do not be afraid to work under the supervision of a person who has more advanced knowledge of automobile engines than you do, or take the job to a professional.
