Cooling System

When a car over heats it is not a pleasant experience for the driver. There is plenty of smoke making it difficult to see as you are driving and once you park the car, it can not be driven without further damaging your vehicle. There are two main parts of the cooling system, the radiator and water pump. If a car is running too hot or eventually over heats and shuts down, it is usually due to a failure in the radiator or water pump. Your car may also have a cracked or leaking radiator hose. If you suspect that your car is running hotter than normal you should bring your car in right away before it turns into a serious problem and you are stranded on the side of the road.

Keeping your car from over heating

The engine in your car runs best at a fairly high temperature. When the engine is cold, components wear out faster, and the engine is less efficient and emits more pollution. So another important job of the cooling system is to allow the engine to heat up as quickly as possible, and then to keep the engine at a constant temperature. Inside your car’s engine, fuel is constantly burning. A lot of the heat from this combustion goes right out the exhaust system, but some of it soaks into the engine, heating it up. The engine runs best when its coolant is about 200 degrees Fahrenheit.

The cooling system circulates a liquid (coolant) through pipes and passageways in the engine. As this liquid passes through the hot engine it absorbs heat, cooling the engine. After the fluid leaves the engine, it passes through a radiator, which transfers the heat from the fluid to the air blowing through the radiator.

The cooling system in your car has a lot of plumbing. The pump sends the fluid into the engine block, where it makes its way through passages in the engine around the cylinders. Then it returns through the cylinder head of the engine. The thermostat is located where the fluid leaves the engine. The plumbing around the thermostat sends the fluid back to the pump directly if the thermostat is closed. If it is open, the fluid goes through the radiator first and then back to the pump.

Water is one of the most effective fluids for holding heat, but water freezes at too high a temperature to be used in car engines. The fluid that most cars use is a mixture of water and ethylene glycol (C2H6O2), also known as antifreeze. By adding ethylene glycol to water, the boiling and freezing points are improved significantly. The pump circulates fluid whenever the engine is running.

5 signs your cooling systems needs attention:

  • Coolant leaks.

  • Engine temperature higher than normal.
  • Low coolant level.
  • Dark colored or dirty coolant.
  • Water pump squeaks or leaks.
