This cap basically seals off the edge of your roof panel. It covers where the roof meets another piece of bodywork, often along the edges or where a sliding/removable roof section sits. It’s designed to keep water, dust, and wind from getting in, and to give a clean, finished look. It's not a structural part, it doesn't hold anything together, more of a finishing touch. Think of it as the last line of defense against the elements for your roof. It works with the weather stripping and seals already in place. It’s part of the larger system that keeps the inside of the car dry and protected. It’s usually clipped or bonded into place, so it's a relatively straightforward part to replace. Well, you’ll notice if one of these is missing or damaged pretty quickly – probably with a leak when it rains, or maybe just annoying wind noise while you’re driving. Water getting in can cause rust, damage to the interior, and all sorts of headaches. It also keeps the car looking good. It’s one of those smaller parts that makes a big difference in overall comfort and protection. You can find these pretty easily, we stock a lot of them, and Fixparts Online is a good place to check if you want to browse. Replacing a damaged cap is a lot cheaper than fixing water damage later on. Hassle-free shopping: Cap (MPN 5C3871143) includes a 12-month warranty!
