Putting water in your radiator tank is a common practice among car owners, but it can actually be harmful to your vehicle. Here are a few reasons why you should stop doing it:
Water can cause rust and corrosion in your radiator. The metals in your radiator are not designed to withstand the elements, and over time, water can cause rust and corrosion which can lead to leaks and other problems.
Water can also cause your engine to overheat. Water boils at a lower temperature than coolant, which means that it can't absorb as much heat from the engine. This can lead to your engine overheating, which can cause serious damage if left unchecked.
Water can also cause damage to other parts of your car. For example, if water gets into your transmission fluid, it can cause rust and corrosion which can lead to expensive repairs.
Using only water in your radiator does not provide the necessary corrosion inhibitors, lubricants, and anti-freeze properties that coolant does, and can also lead to clogging of the radiator.
It's important to use the correct type of coolant in your radiator to protect your engine and other parts of your car from damage. Be sure to check your owner's manual to see what type of coolant your car requires and have it serviced regularly.
