Electric fan for better AC at slow speed ?

[hertfordnc]

I'm not looking better performance or better MPG

But i would love to have cold AC when i'm sitting in a parking lot waiting for my family or crawling slowly down the beach.

Is this attainable? How much fan does it take?

On my 04 explorer living in SC in upper 90s my A/C always seemed to have plenty of capacity. I just would put it on recirculate/max A/C which sucks in the cold(er) air from inside the vehicle instead of pulling the hot outside air. I would check your fan clutch is operating properly and also confirm your A/C is in good working order. Check the refrigerant hasn’t leaked out (not uncommon now that vehicle is older).

Having said, that my brothers 2001 Nissan Pathfinder after all brand new A/C system and brand new fan and fan clutch wouldn’t pass enough air through the A/C condenser and it would heat up at stoplights. This is a common complaint with pathfinder owners, and Nissan did install a small electric fan on ones sold in the Middle East.

So I installed 2 generic 8” pusher fans from Summit Racing on the front of the condenser (left the oem mechanical fan) and wired them with a relay to the A/C clutch so they would only turn on when the clutch was engaged. These are amazing and it always has ice cold air even at a dead stop. Brother lives in Las Vegas and works great. In his truck there is a radiator support bar in the middle which is why I did 2 - 8” vs 1 larger fan. The 8” both flow 800cfm which isn’t a ton but in combo with the mechanical fan are plenty. So to specifically answer your question you don’t need much to get it icy cold.

Big recommendation: Make sure to get a quiet one.

The AC in this car works great I have everything i need when it doesn't work great.
I just want more. i want to start the car 15 minutes before it's time to leave work and get into a cold car.

At 800 RPM idle i don't see the clutch fan getting rid of enough heat.

I'm told the Lincoln Aviator has a fan on the front of the radiator just for this purpose.

That might be the better solution.

Yes the Aviator does have a small electric fan in front of the clutch fan behind the radiator. All you probably need is the Aviator fan and shroud and wire it in to come on when ac is selected.

@hertfordnc
Though I favor the mechanical fan setup over electric, I cannot complain about my clutch fan set-up in my '04. In my location, Southwest Desert, we have at least 90 or more 100+ degree days each year, and the dang thing will sit and cool adequately at idle for as long as I need it to.

Still, I gotta admit, the electric fan is more controllable, and is normally always "ON" when AC is turned on. The Aviator idea is IMO a dang good one. imp

Most Aviators I’ve seen in the yards don’t have this. Allegedly some Ex’s came with it.

Still looking as there’s no jumper harness for a quick install. Wanting to see how it’s wired.

Ford uses a lot of jumpers, meaning if your vehicle didn’t come with the accessory, the main harness is typically prewired for it. All you need is the jumper wire that plugs into the harness and the accessory.

This is a simple install for anyone that knows how to use a relay. Do a google search on the pinouts for a standard relay. Need main power (battery/battery post), ground (find a good bolt or borrow a ground already being used), 2 wires to and from the fans to the relay, and 1 turn on wire (run a wire from the relay and splice into the wire that goes to engage the A/C clutch). Or you can wire up the turn on wire to a switch on the dash if you prefer.

There are some websites that show, how to wire up lights or fans. Any of those should be able to show you how. You just have to decide what tells the fan to turn on. Switch or A/C clutch are easy options. Or you can get fancy with a temperature switch.
