How many CFM's to easily cool the engine?

ISpamWithAnime · Jun 30, 2017

First off it's a 1992 2wd

Right now it has a single 700 CFM pusher but still gets warm at idle. I'd like to either mount a puller or upgrade but I'm still using the stock alternator as well.

Is there a preferred electric fan swap?

Taurus fans are well liked by many, seem to fit well, and are readily available.

+2 on the Taurus fan, I have had one on my truck for years, I have a Delta current controller and have had zero issues

Only question for me is do you need to run the fan when on A/C?

JP02XLT · Jul 1, 2017

Yes, you need to create some airflow over the condensor when the AC is on, I run my fan on the low speed with the AC on and its ice cold and have never had an issue with it that way.

Is that a manual switch or automatic from the controller?

E-fan needs a Relay to work, temperature activated, a manual switch is just asking for trouble.
If you do alot of 4 wheeling and water crossings you can add an off switch for e-fan to keep engine bay drier, and you put a BIG RED light on that switch so you know when it is off, lol.

If you have AC then you add e-fan relay activation to AC clutch activation, how you do that is based on your e-fan relay setup and AC activation circuits

Temp & AC needs are all controlled by this controller, I have tried other controllers this one is by far the best I have seen. I have also done the seperate relay setup for temp & AC, this blows all other methods out of the water, if you want something trouble free.

All done automatically for you

Thanks for link!

Factory mechanical fans will move a few thousand cfm, I try to keep that in perspective when selecting fans. Taurus fans work great or dorman 620118

What engine do you have? Why go away from the mechanical fan?
