what do you think about switching to an electrical fan.will i get more horsepower and better gas milage? its for a 2002 explorer

 

It should help some, but don't expect anything too dramatic. Did you figure out your TBS problem?

 

i took the tbs out ive been having trouble for weeks with it.now the truck runs much better.i already have a k&n fipk with a tornado in it i guess thats good enough for now

 

If I were you, I would throw away the tornado. It does nothing except take up space. It's been proven so. My 2¢ worth.

 

The electric fan set up will put about twenty more HP to your rear wheels. This is one of the cheapest mods you can do to get that much HP gain to the ground. There is Perma Cool, Flex a lite and Performance Products just to name a few that all make kits for the Fords. Check mine out in my Gallery.

 

How is the installation? I'm not very mechanically incline so I was wondering if it's a tough job. Are the instructions easy to read?

 

Its not too bad of an install. I've installed both types of mounts with electric fans and I'd have to say that I prefer the mounting system on the FlexaLite or the PermaCool. You basicilly have to remove your existing clutch fan and shroud then install the new electric fan onto the radiator. The wiring is a pretty simple install also, with your power going direct to your battery or alternator, ground and an optional shut off switch for cab mounting. If you are using a 60 amp alternator, you will need to upgrade it to a larger unit also.

 

yes remove the tornado at once it has been proven a gimmick! swriling air down your intake does nothing to help your power.

 

electric fans are defineatly a big improvement. I got one from a 96 camaro for my 351 for 40 dollars and just fitted it into the fan shroud about an inch from the radiator. Save your'e money and do it yourself instead of buying flexcool or permacool for over $200. The improvement is defineatly noticeable when shifting gears and runs a lot smoother.

 

Hi
I am considering replacing my fan clutch assy with an electric fan and have a couple questions please if anyone can help. I have a 94 Aerostar 3.0 extd with dual a/c. What size (cfm of air flow or diamater) fan should I consider? What about my alternator, how can I determine how many amps it can provide? Also I live in Florida, & drive mostly in city traffic, my a/c can't cool very well in stop & go traffic(a/c checked out & all ok), will this improve my a/c cooling?

Thanks

 

I installed an electric fan in my '89 Ranger (see Danger Ranger for specs). It proved to be great for 3 reasons:

Performance - Yes, you can feel the difference. It will also reduce the load on your water pump bearings!

Off -Road - The fan can be turned off for water crossings or deep mud, saving the fan, radiator, and your ignition (from getting soaked) at it's most critical moments.

Efficient cool-down - The fan can be wired from the keyed lead (using a relay) or directly to the battery. With a thermostat and direct power from the battery, the fan will cycle on & off after you turn off the truck and continue to gradually cool your motor. Normally if you park your vehicle right after hard driving, the water pump & fan stop and the radiator has a very difficult time dissapating the heat - especially water trapped in the block. With the electric fan (in this configuration), the engine cools faster and helps the natural convection process - circulating the coolant and cooling it all. This is a love it or hate it mod, depending largely on wherther you can tolerate the sound of the cycling fan after the engine is off. It is great to see people jump as they walk by in parking lots, though!

Very Important!! For A/C vehicles, you must include a relay to turn the fan ON whenever the A/C is turned on! Failure to do so will not only result in the lack of cold air in your cabin, but DAMAGE TO THE AIR CONDITIONING SYSTEM due to overheating refrigerant!!!

 

I decided on passing on this particular Mod and going with an Air Intake by either K&N or AF1 when they are avialble for the 2004 4.0L's, and a flash unit instead. These two Mods will compliment the Magnaflow exhaust and will give me the extra punch that I'm looking for.

 

If your looking for more available HP, the electric fan modification is really hard to beat for a simple bolt on, one of your best increses in HP for the $$ spent.

 

does the relay for the a/c come with it? how hard is it to add in? whats the price too?

 

Nope, you'll have to fab it yourself using a standard automotive relay ( >$5 ) and splicing into the AC switching. It's easiest to tap off of the lead going to the compressor clutch.
