Using these hose clips is easy. Just place them around the radiator coolant hose where needed and tighten them up. Make sure they're secure but don't over - tighten as it might damage the hose. As for maintenance, since they're made of high - quality stainless steel, they're resistant to corrosion. However, it's a good idea to check them periodically, especially if your bike is used in harsh or wet conditions. If you notice any signs of wear or looseness, it's time to replace them. Keep in mind that these clips are designed to fit AS3 Performance and OEM hoses, so use them with compatible hoses for the best results. Also, remember that the photos are just for reference, so the actual product might vary slightly in appearance.
