Radiator caps serve an important function, but they’re not the most attractive item. Adding a radiator cap cover is a good way to add an extra layer of protection while also personalizing your underhood area.
The next time you’re lifting your Mustang’s hood at a show, you’ll appreciate the added style. While these covers can’t replace your radiator cap, they can definitely make it stand out. More importantly, they won't impede the function of your existing radiator cap.
If you're already adding a new radiator, then adding a little extra shine with a cap cover is a great idea. Or, while you're under the hood, replace your radiator hoses if they're looking a little worse for wear.
