How to Replace Windshield-Washer Tubing in a Mercury Cougar

Figure out if your windshield-washer tubing is clogged. Occasionally the little holes on the ball of the sprayer become clogged from washer fluid build-up or from hard water. You wouldn't need to replace the tubing if this is the case. Simply use a pin or sewing needle to poke a hole to eliminate any debris.

Purchase windshield-washer tubing from a car parts store. The tubing might also be referred to as vacuum tubing. There are no specific part numbers to buy. If you need assistance, ask at the store.

Locate the old tubing. It can be found near the windshield washer fluid reservoir, which is located in the bottom left corner of the engine compartment.

Remove the tubing. Be careful around the vacuum connectors. Try not to break or disfigure them if you plan to reuse them.

Hold up the old windshield-washer tubing if you plan to replace the entire section. Place the new tubing next to the old, using the old as a guide to the length your Cougar needs. Use a hose cutter to cut enough of the new tubing to fit your Mercury Cougar.

Place the new tubing in your Cougar. Use the old connectors, or insert the new ones, and ensure the tubing doesn't interfere with any other engine parts. When closing the hood, be extra cautious to make sure the tubing doesn't get bent.
