Howdy folks, am new to this forum, but have done a search, and can't seem to find the answer... and although I hate resurrecting an older thread... this one seemed to make sense, if not, my apologies.

I have an '04 F150 FX4... driving down the highway, she blows nice and cold... sitting in traffic, here in AZ, she gets pretty warm.

Ok, seems to be she is not getting enough air across her condenser during idle and stop and go driving.

Am thinking of putting a pusher efan on the condenser...

Anyone had any luck with that? How did you mount it if you did?

Looks like I may have to mount one either left or right, as my '04 has a bar that runs top to bottom of the center of the condenser... or, do I attach "2" efans, one right and one left... or would a 16 inch pusher mounted on drivers side of condenser suffice?

Any advice/suggestions appreciated. I am hoping to do this this weekend... gets warm sitting in traffic.

Thanks!

Ron F.

 

I think its the Rad fan that's the problem they are famous for the fan clutch going out. You should try an e fan and let us know how it worked.

 

Have had the fan clutch etc checked all appears fine... I'll definitely post an update once I do the efan pusher mod...

Also, just to complicate matters a bit... which do you think may be best... the Heater Core Bypass valve mod.... or the condenser pusher fan?

and again... when/if I do the pusher fan... one fan ok? Mounted left or right... or two fans?

Now, the heater core mod sounds interesting as well... wonder which will be better... both for AC and for the truck - opinions?

thanks!

 

It's easy to tell if your condenser is getting enough air flow When at idle. when you're not getting proper cooling from your ac check the lines in and out of the condenser the in line should be very hot and the out line should be almost ambient temperature.

 

The Ford truck system is not right, I'll grant you that. But, to the question, there are two things working against you in that scenario - no road speed to get air across the condenser and engine RPM below 1500 which is pretty much the low threshold for AC. If you want to see immediate cooling, hold the RPM between 1500 and 2000.

 

OK, have decided on installing 2 12 inch pusher fans in front of the condenser...

For the fan mounts... I plan on using alum brackets to mount.

The two 12 inch fans, draw 25 amps (Hayden) each.

Now, have purchased the following

* 2 12 inch fans
* 2 30 Amp in Line fuses
* 2 30 Amp Toggle switches
* Plenty of 10 gauge wire

My intent would be to hook these up so that they only get power after ignition. that way there, if I forget to turn off... won't drain the battery.

can anyone lay out a step by step to wire this... where to grab power, where to get into the cab from under the hood?

I mean, I can't just run the positive from the fan to the battery post, then splice in one of the 30 amp switches, as that would mean it would run when truck is not running.

you can tell, I am by no means an electrical guru, but would like to do this on my own...

Not sure how relays work or if needed? And how to hook up...

Am I making this more complicated that need be? I want a simple set up... and don't even mind if both fans are run off of one switch.

So, would like power to fan only when:
- Switch is on
- Truck is on

either of those is false, no power.

Have done plenty of searches and found tons of info, but nothing specific to this.

Any help or suggestions appreciated.

P.S. And of course will post results once all is done...

 

My A/C will freeze you out. Idle or going down the road. I put a can of A/C pro in mine after I had to replace a line I put my fat foot on replacing the TB gasket... All my A/C leaked out and I refilled it according to spec with a gauge with the A/C Pro... ever since my A/C will freeze you out. The little temp gauge I got says 37 degrees... I actually have to move the little **** up towards the heat end because it gets so cold.

 

Hmmm, so you think the can of AC Pro made the difference?

How was your ac before adding the AC pro... did it blow cold on the highway, but tough to get cold in city?

Thanks!

Ron

 

well with the heat we have been having i added a 10" pusher fan in front of the condensor for sitting in traffic took care of the problem ac and keeps the engine temp down while sitting in 105 degree traffic just put it on a toggel swith when i want or need extra cooling

 

It had trouble keeping up in the high temps, and my truck is black with a black interior. It cools off faster then it did before, and it I think it blows cooler sitting in traffic.

 

Did you ever get out and check the in and out line temperatures of the condenser when you're in traffic or having cooling problems? That will tell you What's wrong much faster then we can.

 

Re; checking the lines temps etc... a trusted garage and the dealer said all was fine. Sigh.

They both suggested efans. Lol.

I have bought all the equipment now... and was gonna attempt to install my self... but seems a bit trickier than I hoped...

Ideally I was looking at using the AC on to fire the power to the fans, with two manual switches in the truck... but am not 100% how to wire that up... had my garage tell me, for $125.00 he'd install the equipment I bought.

reckon am heading that way... I just don't want to chance messing up the wiring etc...

for one fan with a 4 prong relay... was gonna:

87 - to Fan 12 Volt (+)
Fan (-) to a ground

85 - AC "on" Hot Wire (so they would come on when the AC ran)
Splice into it???

30 - To Battery 12 Volt (+)

86 - To Ground
(any ground on the truck under the hood)

Using the above I "think" it would always come on when the AC is on.

So, then thought... would be nice to also be able to manually override with an inside toggle switch.

More confusion. Lol
