Things You'll Need:

-
Step 1
Turn off your engine and locate the heater hoses. The Corvette hoses connect to the heater core on the passenger side of the car.
-
Step 2
Drain the Corvette system of coolant by opening the petcock on the radiator and allow it to flow into a drain pan. Keep coolant in a sealed container before throwing it away. Cats and dogs like the smell of coolant, so keep your pets locked out of the garage when changing heater hoses.
-
Step 3
Remove old clamps with pliers or a screwdriver. Take out the old heater hoses by cutting them with a razor blade and then lift the hoses out of the passenger side engine compartment.
-
Step 4
Measure the length and inside diameter of the old heater hoses if you choose to buy a store brand from an auto parts supplier instead of a dealer item to ensure that you purchase the correct replacement hoses.
-
Step 5
Clean the clamp fittings with a multipurpose solution. Then apply gasket sealer to make sure the clamps and new hoses fit securely.
-
Step 6
Push the clamps over the new heater hoses. Add fresh coolant to the radiator and be certain that the radiator is at least half full of coolant to maintain proper operation of your Corvette.
-
Step 7
Start the engine and check for leaks. If you don't see any leaks, then you've successfully replaced the heater hoses and they will function properly.
