A car engine produces heat that reaches 280F in only a few minutes. This is why a cooling system is included to maintain the engine's temperature at a tolerable level. The radiator, fan, and fan shroud are parts of that system, and the focus of this segment is on the fan shroud. It may look like a part your car can live without, but it actually provides an irreplaceable function. Read on to find why, and discover more information.
What's a fan shroud and how does it work?
Basically, a fan shroud surrounds the fan, that's it; but there's an even deeper explanation. Since the fan assists the radiator in cooling the engine, the radiator needs all the air it can get. The fan shroud is designed to gather the moving air from the fan to the radiator. If there's no fan shroud, the air from the fan will scatter, and the radiator will not cool the engine effectively.
Are fan shrouds the same for all types of cars?
Fan shrouds are mostly different for every car type. Although the difference can be minimal, you should remember that it has to equate the size of the fan, and the need of the engine. The material used also varies; it can be plastic, aluminum or steel. Another factor you should consider is the single or dual fan types. To make it easier, check your current fan shroud and see whether it has only one fan or two.
How difficult is it to put a new fan shroud?
If you have a wrench at home and some safety gear, then there's no difficulty at all. Fan shrouds have been designed with bolt-on installation. Keep in mind the size of the fan shroud though, it ranges from 16-20 inches; make sure to get the size you need.
