Your Mustang’s windshield washer reservoir caps and covers are essential for keeping the windshield washer fluid secure and preventing leaks. The Mustang windshield washer reservoir holds the fluid so that it can be used to quickly clean your Ford's windshield when needed.

Over time, the reservoir cap can wear out and no longer maintain a tight seal, resulting in leaks. Upgrading with a new windshield washer reservoir cap will prevent leaks, and a cover will reinforce the cap and add some style. Check out billet aluminum caps and covers with or without logos to add some style to your engine bay.
