How to Replace the Heater Hoses in a Ford Explorer

Worn heater hoses can cause a loss of engine coolant, resulting in damage to the engine that can necessitate expensive repairs. If you notice that the heater hoses on your Ford Explorer are worn, it's best to replace them as soon as possible. Fortunately, this is a job that even novice mechanics will be able to manage without much trouble. Here's how to change the heater hoses in a 1995 to 2001 model Ford Explorer.

Instructions

1

Remove the radiator cap. Locate the plug on the bottom of the radiator and put a clean container under the plug. Loosen the plug and let the engine coolant drain into the container. If you're replacing just the upper heater hose, you'll only need to drain the coolant below the level of the hose.

2

Unfasten the clamps located on each end of the hose that needs to be replaced. If the clamps are the spring type, loosen them by squeezing the tabs on each side with pliers. If the clamps are the screw type, you'll need to loosen them with a screwdriver. Once the hoses are loosened, slide them up the hose, away from the connection.

3

Inspect the clamps. If they are worn, they should be replaced.

4

Slide the hose off carefully, being very carefully not to damage the connector underneath.

5

Put the clamps loosely on the replacement hose. Dip each end of the hose into engine coolant to make them slick and slide them into position on the connectors. Wipe the connectors with a clean cloth.

6

Move the hose clamps into position at least 1/4 inch away from the end of the hose, but be sure they are beyond the raised edge of the connector under the hose.

7

Put the radiator cap and plug back on and pour the drained coolant back into the radiator. Start the engine and let it warm up, then make sure the hoses aren't leaking.
