E-Fans?? Pulleys??........

[bigterp]

Sounds good jmwilso. How tough were the fans to install? Do you have any power issues since installing the e-fans, like lights dimming at idle etc.?? Thanks for the reply man!!!

The install is pretty simple as long as you get a fan clutch removal tool. I got one at Part Source. They have a loan program where you pay full price ($190) for a used tool but get your money back when you return it. I had to slightly relocate what I think is an ABS control unit of some sort. But I only had to move it a few inches back. I've experienced no problems with light dimming or anything of that nature. I set my gryphon to show battery voltage for a while and it all stayed normal. The only problem ive had is that I forgot to check what my engine coolant temp was normally at before the install so I just guessed at what temp to set it. Its currently set to 194 F but I think this may be too low. Ive been looking on the web for what the normal operating range is but can find nothing. If anyone here can tell me I'd appreciate it though.

From what I have seen, my truck usually operates between 195 and 200, but from what i understand anywhere around 200-210 degrees is perfectly normal and healthy, and a little hotter from what I saw on one website will get better gas mileage... just a little though if any at all is what I would say. from what I have seen in my research for E-fans that is pretty close to what they recommend them to be set at, they will never keep the engine at the temperature where they are set at, they will just start working then. Hope this helps

Thanks Ticopowell. I'll tweak mine today then. Maybe it will give me fuel economy a little closer to what I was expecting to get with it. As for holding temp this one does a pretty good job of that. It kicks in at 60% when the ECT reaches the set temp then gradually increases to 100% if the temp continues to rise. It also turns on whenever the airconditioner compressor engages which I'm not sure is competely necessary but doesnt seem to be hurting any.

Thanks again

I installed a Flexalite FLE270 dual fan on my 04-5.4l a while back. I love it.
It opened up space between Rad and and engine,you can change pulleys after install.
The hardest part was figureing out the wiring connection points.
I finally figured out a good fix that made for a clean install. I reinstalled the to deflector over the rad. to push the air down over the engine. My engine coolant temp usually showed 192. I used an infrared thermometer to chec temps a several locations (this is an unbelieveably valuable too and worth the cost) With the fans running and the fan stat set at 190 I was getting rad. outlet temps as low as 160. This caused the thermostat to close and the truck to run at cold Idleor run which uses more gas.
With the thermometer I could adjust temp. control to 220 which gave me an outlet reading of 194 and no more cold run conditions. Saw about 2 mpg increase if I keep my foot out of it like thats gonna happen. Fans don't run very long and stage in so I have not noticed any electrical loading at all. Hope this helps.

Oh, I bought the fan clutch wrench set at AutoZone for 29.50. I have already lent it to a couple of friends for a six pack. that puts price at 15 bucks at this point!

I appreciate all the helpfull info.!!

Tonto87, I plan to do the e-fans and then eventually take care of the pulleys, as these seems to be the most logical progression. The more and more I check out FF Dynamics efan kit, the more I like them. They come with dual fans that have a 6000 Total CFM Rating, which should be plenty for my daily driving and occasional towing. They also come with color coded wiring, which HOPEFULLY will make the wiring process easier. I HATE DEALING WITH ELECTRICTY. I'll be sure to give you all a heads up on the FF Dynamics kit once I get them ordered and installed. Thanks again!!!!

I had the same issue with mine. It was running way too cool. I have since adjusted it up by sitting parked and reving the engine up a bit and then setting the fan to kick in at 210 F but the coolant temp reading on my gryphon still seldom goes over 195 just from ram air flowing through the rad. I'm thinking I should maybe put in a different thermostat valve to get the temp up into the 200s.
