Using these hose clips is easy. First, make sure your radiator hoses are clean and dry. Then, place the clip around the hose where it needs to be secured. Tighten the clip firmly to prevent any leaks. When installing, be gentle to avoid damaging the smooth inner surface of the clip or the hose. As for maintenance, regularly check the clips for any signs of corrosion or damage. Since they're made of high - quality stainless steel, they should last a long time, but it's still a good idea to keep an eye on them. If you notice any issues, contact the manufacturer as the clips come with a 12 - month warranty. Remember, these clips are designed to fit AS3 Performance and OEM hoses, so use them only with compatible hoses.
