These hose clips are super easy to use. First, find the right spot on your radiator hose where the clip needs to go. Then, simply place the clip around the hose and tighten it up. Make sure it's snug but don't over - tighten as it could damage the hose. As for maintenance, since they're made of high - quality stainless steel, they're quite durable. But it's a good idea to check them regularly, especially if you're using your vehicle in harsh conditions. Look for any signs of wear or loosening. If you notice anything off, it might be time to replace the clip. Keep in mind, these clips are made to last, but proper care will make them serve you even longer.
