MANILA, Philippines - Most motorists are unaware that merely using tap water to fill a radiator won’t be enough to prevent overheating. Car experts believe keeping a car in tiptop shape requires regular use of a coolant instead of water, since the right coolants can prevent overheating, rust and corrosion, thereby keeping your car’s cooling system safe from damage all year round. Prestone encourages Pinoy motorists to start a better habit in good cooling system maintenance, and one easy way is to use a coolant concentrate with the right mixture of distilled water. Car owners can also visit the nearest service center to have their radiator systems checked annually, make it a habit to change old coolant at least once a year, and always check the level of coolant at least once a week to top up using ready to use coolant. For best results, always use Prestone coolant (available in concentrate and ready-to-use). It works better than just water alone.
