HOWDY. .

Want to put electric fans on my 12 valve (98 2500)... . Been running with out ANY FAN FOR 2 YEARS,,,,,but going to do alot of CITY STOP and go on vacation soon!!!

Its hard to beat the stock fan setup. I have been wanting to add a electric fan to help out the AC at stop lights and that would have to go in front of the radiator but its tight between the grill and the radiator assembly.

It seems like I read somewhere that "puller" type fans are more effective. With a puller you are not blocking the flow over the radiator by placing a fan in front of it so it seems like when the fan is off the radiator could cool more effectively via the air flowing over it while driving.

Last I checked there wasn't a electric fan on the market that flowed enough air for our mighty engines. Your best bet is to get a Horton Fan Clutch.

This is true, but depending on your climate and use of the truck there are several electric fans that will do the job. There are several TDR members running electrics with good success.



FWIW - I run a Horton fan and the only times it ever comes on are running the AC in city traffic, letting the truck sit too long at idle during the summer months, or severe stop and go traffic, and the occassional backing up of the trailer. All other times the temps stays below 190 even with the fan disengaged. One thing to keep in mind though is I live in a moderate climate and I rarely tow over 5,000 pounds.

Cooker, this is a little off topic but... .



How does the Horton know when to turn on? Obviously you cant run a wire to a object that turn up to 3300 RPM's.

Horton Control

It has a couple sensors that turn the fan on when the coolant temp reaches 205 (or is it 210) degress. It also has a pressure switch that connects to an AC line that will turn the fan on when the pressure in the AC system gets too high. And of course there is a switch to turn it on manually.

OK, but how does the signal get to the fan itself. Like I said, the fan is spinning. Maybe I am missing something.

Chipstien,

I know it sounds strange, but yes, there is a wire loom that runs to the Horton fan clutch. The fan is engaged electrically. In a way, it works a little like an A/C compressor clutch.

I installed one on my truck almost 4 years ago. It is really nice. Quicker warm up in the winter, much quieter when not engaged, no belt chirp on shut down, and it pulls more air than the stock fan when you need it - going up a big grade with a big load.

I run electric fans with no problems at all. Here's a couple of links on how my setup works.

It almost sounds like the Horton fan clutch is mounted somehow to the motor. Am I right.

The Horton fan is belt driven just like the stock unit but has an electro-magnetic clutch instead of the fluid style temp sensing clutch the stocker uses.
