More than the comfort and convenience of being able to control the temperature inside your vehicle, your car’s heating and cooling systems are necessary in preventing your vehicle from breaking down due to extremely high operating temperatures. 
Your cooling system is what keeps your car from having a meltdown, so have it checked every time you have a routine service. All of the parts that make up the cooling system have one goal, moving coolant around the engine so it can absorb and dissipate heat. The system is made up of the following parts: radiator, radiator top hose, radiator bottom hose, water pump, thermostat, thermostat housing, electric cooling fan, and a thermo-time switch.
The radiator is the most prominent part of the cooling system. Every time you drive, your radiator uses up a coolant and water mixture to help lower the temperatures in your vehicle’s engine system. The coolant that has traveled through the engine is pumped through the tubes of the radiator and is cooled off for another round. Coolant, like all the other fluids used by your vehicle, has a tendency to break down over time. This is why it is important to replace or “flush” your coolant mixture. When the coolant breaks down there is more stress on your radiator and your engine runs hotter than normal. Dirt and deposits also build up and reduce your vehicle’s performance. A prolonged use of bad coolant can result in damage to your radiator that would require you to have to replace it. Also today’s engines are built with aluminum, the radiator and heater are also aluminum and aluminum needs much more corrosion protection to keep it in good condition.
How often you should flush your cooling system depends on the type of driving you do and the weather conditions where you live. If you live in an area that has moderate climates, you can flush your system less often. But if you live in an area known for its harsh winter and/or hot summers, and do a lot of driving than you might need to change your coolant twice a year, at the beginning of the summer and the beginning of winter. A basic rule of thumb is every two years or 30,000 miles. But no matter what, you need to ask yourself the question, “is it time for a cooling system flush?”
