Are you actually serious? A "aftermarket" fan will flow much more CFM than any stock fan of the same size. You also act like new electric fans are expensive. I got mine for $75 and it flows more than 2400CFM you find a stock fan that can flow that cfm and I will eat my shirt. $75 IMO is not a lot of money compared to what it will protect against. If you do however consider $75 expensive then you might want to find another hobby...
"Probably one of the biggest mods that many 4x4er's want to do at one point or another is to upgrade the factory cooling system. One of the options available to us is to replace the stock mechanical fan with an electric one. Very high-power electric fans are expensive, so many hot-rodders, rockcrawlers, and general off-roaders have turned to what is considered by many to be the .44 Magnum of the Electric Fan World. The Ford 8C607 2 speed fan. This fan is found in 90-95 Ford Taurus and Lincoln cars with the 3.8L V6 engine. It is also known as the Lincoln Mark VIII fan. It is identifiable by three wires coming from the fan itself." (substitute 4x4er's for 240er's)
quoted from a website i found while trying to find the cfm of the ford fan..it is a two speed fan, on high it is said to pull between 2000-2200cfm. which is more than sufficient to cool the sr20det even with the stock rad. One of the main benefits is that it comes with a shroud that covers the rad almost perfectly which allow it to get the most out of its cfm. im pretty sure that almost all aftermarket ones do not come with a shroud which makes all that cfm less effective (the 300-400 more).
as far as the cost goes i dont consider $75 alot of money for a worthy upgrade..like a hks wastegate actuator...or some rocker arm stoppers.
why pay $75 when you can pay $20-$30 for something that will do the same job.
i think you overpaid for your fan, end of story
would you like some fries with that shirt
