<p>Lots of people don’t maintain their car cooling system properly which can lead to lots of engine problems. Too, many people don’t use the manufacturers’ recommended antifreeze/coolant which can contribute to premature water pump failure. Many coolants today don’t have silicates (kinda like fine, small, small sand particles) in them that can prematurely wear out a water pump…best to use the coolant recommended in owner car manual. There are many types of coolant out there and they don’t all mix well.</p>
