Every system of your motorcycle and its parts should be in good working condition. And the cooling system with its thermostat, water pump, hoses, and a radiator cap are no exception. It is extremely crucial to have a properly functioning radiator cap. The radiator cap helps protect your radiator from overheating and prevents fluid loss. Intended to hold a certain amount of pressure in the cooling system and to dump the pressure when it exceeds the predefined level, the radiator cap can help avoid many cooling problems. So, if you have a damaged or worn out radiator cap, do not put off its replacement.
