2.8 V6 Fan

074EC86D-A56B-4997-88EC-A49A533666AF.jpeg I’ve been pondering what approach to take with regard to the radiator fan for my V6 conversion project and come across this one. It’s from JEGS.... part # 17013...part of their heavy duty stainless flex fan line up...it’s 13” in diameter and has a 2”depth. It clears the water pump inlet fitting nicely. Once we get the engine into the car for mock-up purposes we can determine what size of spacer, if any, will be needed to obtain the best position between the engine and radiator.

It is not an outrageously expensive part...about $45 and bolts right on with no adapters. I know a number of folks have been going with the Volvo fan alternative but since this didn’t require any cutting or modifying of the fan itself I thought it to be a bit more straight forward.

Of course, the proof in the pudding will be if it adequately cools but with a new custom radiator, hopefully there won’t be any issues.

You might need to construct a shroud in order to utilize all of the radiator surface area. But that fan should be adequate.

The shroud is a given...I guess I should have mentioned that...I'll have that built along with the radiator.

An electric fan was my original thought but a mechanical one is cheaper and easier.
I have found they are also more effective, unless you use a monster electric fan that draws 40-50 amps. But if you have room for one of them, you have room for a mechanical fan. The mechanical fans only downside is the constant power drain. That can be mitigated with a viscous drive, but that takes space which you probably do not have.

We're using an electric fan, 16"diameter on the V8 , no shroud, runs at 180 degrees, draws about 30 amps so far we've not needed a relay. I do have a double pass alloy rad.

Bill E I found the listing for the 13" fan.... But had to add the full part number as: 259-17013. It is a Derale manufactured fan made in the USA. Has a depth of 2 and 3/16" Cost $44.00

Also found another 13" with depth of 2 and 1/8" Part Number 259-17213 Price is up to $72.00

The depth difference may could be critical in some cases.

I also looked at the #17213 fan....decided to go with the other primarily due to the price. I don’t know if the 1/16” of depth difference will be enough to be critical but we’ll see...won’t know for sure until I get the radiator specs finalized...

One aspect I recently heard about is that with a mechanical fan without the clutch, will actually decrease airflow since it spins to slow at speed.
Has anyone else heard of this phenomena?

No, and I do not believe it. They do not spin slowly. About 1 1/2 times engine speed. At speed, say 3,000 rpm's, that translates into 4500 R's.
