Using this AS3 cooling kit is easy. First, make sure your bike is turned off and cooled down. Then, remove the old water pump impeller and install the new oversized CNC - machined one from the kit. Attach it using the longer bolts provided and place the gasket properly. Fill the cooling system with coolant. When using your bike, keep an eye on the temperature gauge to see the difference. For maintenance, check the coolant level regularly. If it's low, top it up with the recommended coolant. Also, look for any signs of leaks around the water pump. If you notice any issues, contact the UK - based company for support. Remember, the kit comes with a 12 - month manufacturing guarantee, so you're covered for a year.
