Frequently Asked Questions (FAQs)
1. Are fan shrouds necessary?
If you rely on a belt-driven fan for engine cooling, a fan shroud is a must to pull the air through the radiator. Without a shroud, air will take the path of least resistance, pulling air from over and under the radiator instead of through it.
2. What does a shroud do for a fan?
Fan shrouds are passive air-flow improvement devices. They mount behind your radiator and around your fan blades. In this position, they channel air-flow directly over your radiator and improve cooling-rates in the process.
3. Is a shroud fan better?
A fan shroud does much more than just dress up the engine compartment. A properly built shroud will greatly improve the efficiency of a pull fan as it draws air through the radiator. The circular area of even a large fan is significantly smaller than the rectangular surface area of the radiator.
