Using these hose clips is easy. First, make sure your radiator hose is clean and dry. Then, place the clip around the hose where you need it. Use a suitable tool to tighten the clip until it fits snugly. When installing, be careful not to overtighten as it might damage the hose. As for maintenance, since they're made of stainless steel, they can withstand different conditions. But it's a good idea to check them regularly for any signs of wear or looseness. If you notice any issues, replace the clips right away. Keep them in a dry place when not in use. Remember, these clips come with a 12 - month warranty, so if there are any problems within that time, you can get in touch with the manufacturer.
