I have a 01 2.5L that still has the stock clutch fan. I just remembered I had a 16" EFan in my shop and thinking about installing it on the Ranger. I just want to make sure that the CFMs that the EFan has will be as much or more than the stock clutch fan. Anybody have an idea of the CFMs for the stock fan?

Thanks

This is the fan I have.

Can't really compare mechanical fan and E-fan CFM

Reason being e-fans are on or off, some may also have a high and low, but their CFM will be constant when ON, i.e. 0 CFM(off) or 3,000 CFM(on)

Mechanical fans spin at engine RPM which doesn't stay the same, hopefully, lol.
So how would you rate CFM?
At idle RPMs
At, 1,500 RPM
At 4,000 RPM

E-fan CFM is also rated with free-flow, no radiator in front of it, so e-fan with CFM of 3,000, would probably be 1,500-2,000 actual CFM when installed

The mechanical fan CFMs I have seen were "real flow", installed in place with radiator and shroud
And the 1,500-1,800CFM comes to mind and at "mid-RPM" so may be 2,000 rpm

An e-fan delivering 1,500 CFM "real flow" constantly would be more than enough IMO

Radiator fans are only needed at lower speeds or when stopped because vehicle moving provides enough air flow thru the rad, which is why e-fans are better, they are off when on the highway so better MPG and power, and then they come on when you slow down or stop when MPG and power are not a concern.
Mechanical fan is on when engine is so............always using MPG and power
