When any of your car's heating or cooling equipment goes wrong, it can have harmful effects on your car and make you, the driver, less comfortable. The design of modern cars gives you a constant flow of fresh air to keep you comfortable when driving with all of the windows shut. This air enters your car through a large duct at the front, or through grilles on top of your bonnet. Designers place the ducts and grilles in just the right position to force the air through at high pressure. From there, the air goes to the heater to warm you up when needed. Your car also includes an electric fan to cool you down when your car is stationary. Meanwhile, valves attached to a thermostat allow you to change temperature. In fact, the system includes many valves, hoses, clips, pumps, gaskets, an intercooler and more. Every one of these parts, no matter how small, is vital to the efficient running of your engine. So when it is time to change any aspect of your car heating and cooling system with quality components, you can be sure that Euro Car Parts has exactly what you need.
