Using these hose clips is easy. First, make sure your radiator coolant hoses are clean and dry. Then, place the clip around the hose where it needs to be attached and tighten it properly. When installing, be careful not to overtighten as it might damage the hose. As for maintenance, since they're made of high - quality stainless steel, they can withstand different conditions. But it's still a good idea to check them regularly for any signs of wear or loosening. If you notice any issues, replace the clips right away. These clips come with a 12 - month warranty, so if there are any problems within that time, you can get them replaced.
