Using these hose clips is easy. Just wrap the clip around the radiator coolant hose where it needs to be secured. Make sure the clip is tight enough to prevent any leaks but don't over - tighten as it could damage the hose. When installing, check that the banded edges and smooth inners are properly placed around the hose for the best protection. As for maintenance, since they're made of 18/8 marine - grade stainless steel, they're quite resistant to corrosion. But it's still a good idea to clean them occasionally with a mild soap and water solution. This will keep their polished finish looking great. Also, if you notice any signs of wear or damage during use, it's best to replace the clip right away. Remember, these clips come with a 12 - month warranty, so if there are any issues within that time, you can get in touch with the manufacturer.
