Installation is a breeze, no cutting or drilling of your car required, and it's easily reversible. In just 5 minutes, transform the look under your hood.








Using these fluid reservoir caps is super easy. First, make sure your car is cool. Then, take the seal from your factory brake fluid cap and put it on the new brake fluid cap we provided. After that, just replace the factory caps with our new ones for the brake fluid, coolant reservoir, and washer reservoir. There's no need to cut or drill your car, so you can do it yourself. As for maintenance, keep an eye on the caps every time you check your fluids. If you notice any signs of damage or wear, it's time to replace them. Also, since these caps are made of high - temp material, they can handle normal engine heat, but avoid exposing them to extreme heat sources outside of the engine. That's all you need to know to keep your car looking great and running smoothly with our fluid reservoir caps.
