Do I really need the twin fan setup or could I go with a single 16". I don't see how I need that many cfm's even with air conditioning. Just a thought.

 

I've been running a single 16" for years. But then I've also got the coolest setup...a V6 with the 5-sp.

 

I got a single 16 on my 4.6l, had to try it for the price ($90 through Advance) Have had no problems, install was easy, but I did wire mine with out the thermostat control. Haven't had a problem with A/C. Had a A/C guy look at it and said with a duel fan set-up I could get about 4 or 5 degrees cooler but for the price I can live with what I have.

 

I ran one 16' fan the first year that I changed to elec. fans. Did have a problem, first time, pulling a heavy trailer in down town Nashville, TN going one block, stop light, one block, stop light,etc, you know what I mean. Any way the temp gauge started to rise very rapidly and I instantly turned A/C off and rolled down the windows and ran the heater on high to get the heater core to work for me. After a block or two the temp started to go down and I was able to shut the heater off, and left the A/C off till I got to clean air moving thru the radiator. Second time that it failed me I was idling in a parking lot with the A/C on for about ten minutes. I'm rambling on here!
Since I have added the second fan and changed the wiring to cycle one fan on/off with the A/C compressor, very rarily does the second fan run and even then only for a seconds, 30 maybe.
I'm running the single core radiator and a 5.4 I feel one fan is border line and would work if a person watched what they were doing, but then you never know what the person that y ou loaned your truck to for errand would do, or even notice.

The second fan make it fool proof. " No Worries Mate"

Yup....deffinately go with 2 fans. I got the Troyer kit and have been very happy with it. Comes to keeping that engine cool there isn't room for skimping out on anything.

 

Where did you get your dual fan kit? I am thinking about doing the same thing. Also, how much? Thanks.

the above site
has a good kit and they are nice people to deal with. He is also a sponsering member of this board. A lot of the people on this site use his fans.

Thank-you. Have the forum members that have the electric fans noticed the horsepower and mileage increases as noted on their webpage? I could definately use a couple miles per gallen increase.

 

If you do decide to go with the Troyer kit , it comes with two controllers with multiple leads that are not normally utilized with the instructions. I have set mine up where the second fan (the one that does not have the AC input) has a manual control so that I can flip it on at any time. I also have the secondary fan controller leads wired to LEDs so that I can see which fan is currently on .

I installed a two pod A-pillar guage mount and I have the LEDs and switch mounted on a blank in the bottom pod and a mechanical temp guage mounted into the top pod. I have the temp guage sensor spliced into the heater core input hose (Thanks to a posting to Neil I found in the archives). The power for the guage/by-pass switch is tapped into the ACC power wire that is used for the fans. The cost of the guage, A-pillar mount, switch, LEDs, and wire was about $60 and about 3 hours of additional labor.

Good luck with whatever you choose, there are a lot of options.

Tsquared,
were did you purchase your A pillar guage pod? And does tapping into the heater input hose give you a correct reading even if the heater core valve is closed and not circulating water?

Thanks

I picked mine up at an Ace Hardware Auto store. You can get them at Lear Truck Centers, PEP Boys, and NAPA also. Here is a good link that shows a 3 pod install in a F-250. The F-150 works the same way. I recomend that you wire the guages the way that you need them and pull them from the pods to where they need to connect to 12+, Ground, or sensor. A good place to get 12+ is the starter relay on the passenger side firewall. Ground can be found on any metal bolt under the dash (verify with multi-meter).

The heater core has water circulating all the time. It is an accurate account of the temp of the engine water. The cold/warm adjustment on your dash controls a plenum duct in the dash. The design of having a heater core valve has not been around for quite some time.

 

Thanks Tsquarded, I have both Ace and NAPA close by I'll check them out.
