Review of Flex-a-lite Radiator Fans FLX418

Today we're going to be taking a look at a Flex-a-Lite 18-inch nylon engine cooling fan. The Flex-a-Lite nylon fan moves a lot of air and weighs only 11 ounces, so it's a nice, lightweight design. It's going to be ideal for race and performance applications when cost and weight are very important. This is a belt-driven fan. Now, keep in mind that belt fans must be used with a fan shroud. It's going to feature standard rotation. Fan diameter edge to edge is actually 18 3/8 of an inch, so it's in that 18-inch diameter category.

To be exact on the overall diameter it's 18 3/8 inches. The bolt pattern, you can see how some of these holes are elongated here. This will fit 1 3/4 to 2 1/2 inch bolt pattern applications. The project width or thickness is around two inches. That pilot hole diameter, center hole right here, that's 5/8 of an inch. As you can see it's a six blade design.

It's going to have an RPM rating of 8,000. It does come with some new hardware. The hardware that it comes with, it's going to come with four flat washers and four serrated washers. That's going to do it for today's look at the Flex-a-Lite 18-inch nylon engine cooling fan.
