Using these hose clips is easy. First, make sure the radiator hose and the connection area are clean. Then, place the clip around the hose at the appropriate position. Tighten the clip securely, but don't over - tighten as it may damage the hose. When it comes to maintenance, regularly check the clips for any signs of corrosion or looseness. If you notice any issues, replace the clips right away. These clips are made to last, but in harsh environments, more frequent checks are recommended. Keep in mind that these clips are designed specifically for 2021 - 2025 Aprilia RS 660, so make sure to use them only on compatible vehicles. Also, don't forget they come with a 12 - month warranty, so if you have any problems within that time, you can get support.
