How to maintain a radiator

Yes, the radiator takes care of your engine but you also need to maintain the radiator to make it last longer. We suggest that you keep the coolant or fluid-filled at all times and place the radiator cap tightly to ensure that the coolant chamber stays pressurized. Also, make sure that you have the radiator flushed, cleaned, and filled at least once a year.

Can I put water in the radiator

When riding long distances, you may sometimes be tempted to add water to your radiator. While it may be done, we suggest that you use a mixture of coolant and water for the best results. Plain water reaches boiling temperature before coolant, hence it may cause your engine to overheat.
