E fans??
Am thinking about upgrading to Efans on my 1989 bronco with a 351W... What is the best way to go?? I know wrecker taurus Efans are easy to come by and are 2 speed I think... and the price is good... are they worth it though?? or is that a good aftermarket one that costs less than an arm and a leg??
Thanks!
Bob

I would not consider an electric fan and upgrade unless I drove mostly highway miles. Around town is when you need the fan, and whether you drive it mechanically from the engine, or electrically from the alt which is mechanically driven from the engine, I don't see much difference.
Now if you did a lot of higher speed highway driving, then I can see eliminating the drag of the mechanical fan and advantage. You can't turn it off, but you could turn the electric fans off, since you do not need a fan with all that airflow.

I have e-fans on my 90 302 in the 150 and they rarely come on in the city. they kick on at 200 and of at 185 with a 180 thermostat. I have on off a taurus I paid 20 bucks for. From summit racing you can get a thermostat for 20 bucks and wire it in yourself. I have mine automatic with a switch for manual override.

Got headers?
When I put e-fans on my '86 E-250's 351W, the fans worked great for the radiator, internal engine temp, etc.
Come to find out that, while idling, the fans were not blowing enough air to blow away the heat from the headers. Started getting vopor-lock symptoms, engine parts got too hot to touch, even the metal part of the fuel line was too hot to touch.
Make sure you get a large enough air flow for your application.

Munrow a van is a very tight area anyways. if the headers were putting off that much heat your motor is running lean.
now running electric fans is a good idea but remember its electric and if you have an issue out on the trail you will wish that stock fan was still on there. but those taurus fans will keep the motor plenty cool even out on the trail.
Franklin at hwy speeds the fan is barely going to be turning because of the clutch. its at slow speeds that the fan would be creating more drag like in town or offroading.

Thanks for the leanness tip, Kemicalburns.
I tried the E-fans on the other engine, and, very probably didn't have the carb set for the correct fuel mixture.
On the new setup, I turned the fuel inlet screws all the way in, then backed them out 1+3/4 turns.
Exhaust is too loud to tell if any pinging is going on. I've consigned myself to re-rebuilding this engine soon (stroker 393), so it doesn't matter much.
Can't wait to rebuild! I reaaallly like how the engine compartment looked without the stock fan.
Thanks,
Munrow

I've been running FAL 295's for two years on my supercharged rig without any issues.
They're pricy, but they work very well in this GA heat. If you're looking for something a little cheaper then a fan from a Lincoln Mark 8 and Painless E-fan kit will be less expensive.

I haven't put on an electric fan but have been considering it, my 302 has been overheating in the 100F+ heat here.
I think Franklin has it backwards. I have little trouble with highway! But in town, when not only is there no forced air from forward speed but the engine thus fan RPM are low, the temps shoot up. An electric fan would provide MUCH better cooling in these conditions.
The fan out of the Lincoln Mark 8 (VII)- look on eBay ($50-$100)- is the fan to use. Aftermarket fans are a joke! The CFM of airflow is quite poor and it covers little of the radiator. The Mark 8 fan pulls very high CFMs and the shroud it comes with is well sized for a Ford radiator. This fan will take a substantial amount of current.
The stock Motorcraft 2G alternator- comes with retarded plug for the power rather than a stud- cannot power a fan. It will burn up internally, burn up the plug, or simply let the battery run down. You must upgrade to a 3G (also eBay) which is one of the top alternators made. Extremely high output and extremely reliable. The alternator bracket must be removed and ground down a bit to be made to fit.

I'm not going to dispute that the Mark 8 fan is an excellent upgrade (as I stated previously), but to say aftermarket fans are a joke is ridiculous. For example, if you're running a set of FAL 210's, then I can see why your rig gets too warm (especially if you live in the south)...the fans and the shroud are too small for a full size pickup. Now an FAL 295 or 298 covers the ENTIRE radiator, it has a VSC that can run at two speeds and it starts up slowly ease the load on the electrical system, A/C trigger, Manual operations etc... If all he is looking for is a switch on/off fan that is triggered by a probe, then the Mark 8 will work great!
I have ran the 210's and now run the 295's, and the 295's have yet to let the temps even flirt with "a little too warm".
