Vw Radiator Fan

by : John Garett

The Volkswagen engine packs a mean combustion process that goes way beyond normal temperature level. This is important in order to have an efficient combustion process on the air/fuel mixture inside the engine cylinder. A certain amount of percentage of fuel is converted to heat along the process. But if this heat goes into excess levels, chances are, it will melt out the internal parts of the engine. The pistons expand that they would not be able to fit the cylinders. Thus, overheating may occur. It is in this premise that a cooling system is required to keep engine temperature at bay and to prevent it from overheating. Not only that, the cooling system makes use of this excess heat to warm up the innards of the vehicle during cold weather. The two types of cooling system in the Volkswagen consist of: a) liquid cooling and b) air cooling. On the former, a liquid which is commonly called a coolant (usually water mixed with anti-freeze) circulates through the pipes and and passageways along the confines of the engine. It absorbs the heat from the engine and goes out to pass through the heat exchanger (or radiator) to transfer this heat to the air blowing through the exchanger. While for the air-cooling type of system, the engine block is concealed in aluminum fins that conduct the heat away form the cylinder. A fans blows off potently over the fins, cooling out the engine by venting this heat through the air. Be it a condenser fan or an automotive fan, the draws air outside the radiator, aiding the radiator to dissipate heat more conveniently. Snugged fit in front of the radiator, the VW Radiator Fan comprises vital elements like the fan blade, fan motor, fan belt, fan clutch and fan shrouds. Different specifications may be preferred as to the blades. The configurations may vary according to the needs of the owner, like the blades may be ranging from four to eleven blade set-ups. Usually made of high-grade plastic, these blades spin at top speeds to help the radiator in cooling off the heat passing through its fins. But it should not be at all times that the VW Radiator Fan be spinning at optimum speeds. Like the thermostat, it has to be regulated to maintain the ideal engine temperature. A thermostatic switch or a computerized chip signals the VW fan to activate when the temperature of the coolant goes beyond set point. They turn back off when the temperature goes below it. As for rear-wheel drive Volkswagens with longitudinal engines, an engine-driven VW fan is mounted. The one that acts as the thermostat is the clutch, installed at the fan's hub. They are very much alike with the viscous coupling found in some all-wheel drive Volkswagen cars. With the different specifications of the VW Radiator Fan according to the desired requirements auto parts dealerships provide a wide range of fan assemblies for the different Volks vehicles---be them model or year. Over at cyberspace, a great deal of inventory of fan assemblies await for online purchasers, with great deals on the parts, themselves. The buying public is assured that these products are not run-on-the-mill types, as they are precision-made to meet the strictest standards that even exceed industry expectations.
