Using these hose clips is easy. First, make sure your radiator hoses are clean and free of any debris. Then, simply place the clip around the hose where it needs to be secured. Tighten the clip firmly, but don't over - tighten as it might damage the hose. When it comes to maintenance, since they're made of marine - grade stainless steel, they're quite resistant to corrosion. However, it's a good idea to check them periodically for any signs of wear or loosening, especially if you're using your vehicle in harsh conditions. If you notice any issues, replace the clips right away. And remember, these clips are covered by a 12 - month warranty, so if you have any problems, reach out to the manufacturer.
