I asked some questions here before about flexalite 180 fan with few responses. So I thought I would post my results after some testing.

Originally I had an aluminum radiator with an advanced auto 16" electric fan. The fan was mounted directly against the radiator with no shroud. I let the motor idle and heat up to 200 degrees then turned the fan on. I was able to get the motor down to only 185 degrees in about 15 minutes.
I then installed the flexalite 180 electric fan with shroud and did the same test. I ran the motor to 200 degrees and kicked on the fan. The motor quickly came down to 150 degrees in just a few minutes. I guess im going to have to install a therostat now.

In case anyone wanted to use this fan, it works great.

test information

Car - Miata
Motor - V12 13.5:1 compression
Radiator 26x19 aluminum 2 core
Core size 21x17
Fan Flexalite 180
No thermostat
76 degree weather

That is some good information.

I hope you don't have the same problem with the shroud, as I had with the "Vette" in my AVATAR. The radiator displaces so much heat it started to melt the shroud. I had to have a aluminum shroud made to fit.

According to the specs, that's a pretty serious fan! 3300cfm@18amps.

The biggest thing that made the difference was probably the shroud.

Not sure how well it would work were I live, summers hit 116+ and with A/C it might not make it. I"ve wanted to put electric on my truck for years, just can't justify the cost.

I had very good luck with the flexalite's I used on my cars. and it get's 110+ here.

I live in Florida, so it gets hot here too. Today I did more testing. I ran the motor on the street today at about 40mph and held 4500rpm for 10min. The motor stayed right at 165 degree's.

Kind of on and off topic, but I found an older 180 that's a 15" fan- not a 16"- but otherwise all specs are the same (CFM, Amp draw, etc). It should work just as well, wouldn't you think? Been sitting unopened in a box since 2003.
