I have a 300.i want to remove the fan from the motor and replace it with an electric fan.how would i go about doing this.i know it sounds easy and i could do it,i just would like to know any tips or how tos on the matter.and who of you have done it.
Thanks

 

F-250 restorer has excellent write-ups and pictures posted on this. Do a search of his postings.

 

you don't mention what year truck, but- first step is an alternator upgrade, if you don't already have something putting out 100+ amps.

second step would be finding a way to mount a temp sender that'll trigger the relay.
third step would be mounting the fan and hooking it all up.

 

It is a 96.what does the year of the truck mean for this change out?

 

this forum covers ~35 years of trucks, so there was no way of knowing what alternator you've got.

the 3G was installed in the mid-90s, so you may already have enough amps.
time to ID your existing alternator.

 

My 96 F150 XL came with a 90A alt. i had upgraded to the 130A unit though.

I run my fan from a switch havnet needed to change that yet. Using a fan from a 98 Cavalier. Had no issues with it last summer in the 30*c heat. Warms up in the winter so much nicer too. and the couple of ponys it free up were nice. picked up about 1-2mpg as well

I agree its much simpler to use a setup that turns it on and off all on its own though.

 

Just installed a fan kit on my '94 that I got off Ebay. It came with all hardware, relay, circuit breaker and temp sensor. Works great. The sensor is 3/8 NPT (pipe thread) and came with a 3/8 to 1/2 adapter. There's NO good place to put it on an EFI truck as all the existing tapped water jacket holes are used. However, I recently replaced the thermostat housing. I got one at Autozone for around $10, and when I picked it up I was pleasantly surprised to find that despite the big "Made in China" stamped into the back side of the neck, instead of being made of the factory Ford unit's "break if you look at it wrong" pot metal it was cast iron! Also had a nice, beefy unused boss on the side of it. I drilled and tapped this for my sensor. As I said, works great (although I think I'll find a different switch as this one comes on too soon and runs too long). Here's the one I bought: 16" Electric Fan CFM with Wiring Install Kit Complete Thermostat 50 Amp Relay | eBay

 

Why not let the fan control switch regulate the radiator coolant temperature and the thermostat regulate the engine coolant temperature.

Switch on the cold side of the radiator.
That's essentially how the clutch fans work.

 

200000+F150- thanks man i look at the link. I might go with that one.are you getting pretty good airflow out of the fan?

 

I went to the junkyard and bought a fan out of a '93 Taurus. If you turn it longwise vertical, it is almost perfect height for the radiater in my '81 F-150.

I had already purchased an electric fan, and simple adjustable temperature control from LMC. The LMC fan mounted too close to the radiator and was cavitating (not drawing air). The Taurus fan has a nice shroud on it, is capable of running at two speeds (three wire hookup) for the future when I can afford a two-speed controller setup. I would also like to put some sort of starter capacitor in my system to prevent fuse blowing. The first time I started it with a 20A fuse in line, it popped handily. I think the surge current blew it, not the run current.

Any ways, just a thought for a cheap way to do it, instead of blowing $100+ and then throwing it on a shelf like I did...

I did an article for True Blue Truck magazine on the conversion. You can do the conversion for about $80, and get a fan that blows away the ones on ebay. What you want is the dual fan out of a circa 2000 Contour or Mystique, with the 24 valve engine. Space is tight with an inline 6, so, although the Taurus fan is a great fan, it just won't fit. The Contour fan is low profile, thin, and moves 3500 cfm!

The controller you can get at A.Zone for about $20. Then take the relays from a mid nineties Taurus with the 3.8 liter engine. In my write up I posted a wiring diagram and all the goodies. You can also use the alternator from the same taurus, 130 amp. Do a search and find my write up.

The oem Ford fans are FAR superior to any of the aftermarket ones. Also, they are cheap at the j/y's and easy to find. I also took an extra motor, and wired each fan independently in case one goes out the other will still function and I can get home.

I always laugh when I remember what one guy said about this fan: "It will suck a cat through the radiator." I have been running this system for ... about 1 1/2 years w/o incident. It cools the engine in about 2--3 minutes of running time. I can even tell when the radiator coolant is low--due to a leaking heater core--because the level drops below the sensor in the radiator, and the fans kick in when the temp is a bit higher than normal. It is one of the best upgrades I've done on my truck.

 

You don't happen to have a scan of that article do you?

Used the cavalier fan as there was one in the shop.
