Using these hose clips is easy. First, make sure the hose and the radiator are clean. Then, simply place the clip around the hose where it connects to the radiator and tighten it. When tightening, don't overdo it as it might damage the hose. As for maintenance, since they're made of stainless steel, they can withstand corrosive environments well. But it's still a good idea to check them regularly, especially after long rides or in harsh conditions. If you notice any signs of wear or looseness, it might be time to replace them. And remember, these clips are made to fit AS3 Performance and OEM hoses, so make sure you're using compatible hoses. Also, keep in mind that the warranty is for 12 months, so if you have any issues within that time, you can contact the manufacturer.
