Your engine produces a lot of heat and needs a way to get rid of it. The cooling system is that way. By transferring heat from the engine to water flowing through the engine it can carry the heat away. The water is then cooled in the radiator before being circulated back through the engine via the water pump to remove more heat.
When your cooling system is functioning properly it allows the engine to overheat which can cause serious damage to engine components, most commonly blown head gaskets.
Always have leaks repaired quickly and never allow the system to run out of water/coolant. Your cooling system should always be inspected during service visits for signs of damage or failure. This may not prevent all failures or issues but it can definitely prevent many.
Your cooling system is also responsible for producing heat in your vehicle during winter months. A heater that is blowing cool air could be a sign of low coolant. Check it immediately and top it off. Then schedule an appointment to have it inspected.
