There should be at least 1 inch of clearance between the two. The last measurement you should check is the distance from the face of the fan to the radiator. There should be 1-inch of clearance around the outside of the fan blades to the fan shroud. This can damage the fan shroud and the fan. If there is not enough clearance, you run the risk of the fan contacting the shroud with natural engine movement and body flex that affects the radiator and fan shroud mounting. If there is too much space here, the fan won’t be as efficient as it could be in pulling air through the radiator. The other very important fan to fan shroud measurement is the distance around the circumference of the fan and the circular opening of the shroud. This causes dissimilar resistance along the length of the fan blades, which stresses them. It’s also important that the fan blades do not extend past the top, bottom or sides of radiator surface. Make sure you use Flex-a-lite spacers using any other brand with a Flex-a-lite belt-driven fan will void the warranty. You can use 1 or more spacers – up to 3 inches in total. We manufacture a variety of fan spacers to move the fan forward and rearward, letting you achieve the optimal position. If the blades are not far enough inside the shroud, the fan will pull air from around the shroud rather than through it. Instead it will create turbulence inside the shroud, spinning the air, but not efficiently pulling it through. If the fan is too far inside of the shroud, it won’t pull as much air through the shroud as it could.

Looking from the side of the engine, the fan blades should be half in and half out of the shroud. If you have a fan shroud, the position of the fan blades in the shroud is very important to maximize airflow. Most people that have cooling problems with a belt-driven fan at idle and slow speeds don’t have a shroud – their fan is drawing very little airflow through the radiator, and most of their cooling comes from ram air being driven through the radiator at speeds above 40 mph. Without a shroud, air will take the path of least resistance, pulling air from over and under the radiator instead of through it. If you rely on a belt-driven fan for engine cooling, a fan shroud is a must to pull the air through the radiator. The first thing we want to make sure is that you actually have a fan shroud. It’s critical that the fan be positioned properly within the fan shroud and that there is just enough clearance around the fan blades.

High Quality Light Weight Full Aluminum Construction Shroud Investing in proper maintenance though will considerably benefit the ride and driving quality in maintaining the ideal working conditions of the engine. With excellent operating temperature management, allowable levels of engine temperature are stabilized. The fan shroud basically houses the fan blades securing it in place and keeping it from damaging the other engine components that may disturb the smooth and even operation of the engine. The fan and the fan shroud effectively drive the heat over and out the engine compartment rather than thrusting it into the front of the engine. It facilitates the function of the radiator fan as it contributes in the maintenance of the ideal range of operating temperature in the engine. Crafted from heavy duty Aluminum materials, the part efficiently addresses harsh working environment. Among the less frequently seen part of the cooling system is the fan shroud. This is where a vehicle cooling system comes in focus.
