Geez, I replaced the clutch fan in my 2000 3.0 a few weeks ago. Now this thing "roars" whenever I'm at idle and take off, until I get to about 30 MPH. It certainly works as it should, but that roar is driving me nuts.

Luckily, I saved my e-fan setup I had with a 2005 F-150 I used to own. It used a Mark IV fan setup from a Ford car (2 speed fan), and a seperately purchased DC controller. All that I need to do is install the efan within the stock shroud using plastic spacers at 4 corners with nuts/bolts and wire it up. This should take me about 2 hours to install.

Quieter, more effecient, and less paristic drag on the 3.0.

 

E-fan is a great mod for sure i love mine.

 

It sounds like your new fan clutch is not working properly unless it is happening when the air temperature is really hot.

When I start my Ranger in the morning, I can hear the fan for about a block or less as I drive it. It then gets quiet. The only time I can hear it after that is if the air temperature is hot and the fan clutch engages to draw more air though the radiator for better cooling.

I have nothing against E-fans and think they are a good way to go if done properly. I also think a properly working fan clutch system is very effective.

 

E-fans have a few pluses for 4x4ing
Slow off-road driving(crawling) can raise temp because of low speed(air flow) and low RPM, E-fan keeps temp down.
You can turn them off(if you added the switch) in higher water crossings, anyone who has had belt driven fan in the water knows what engine bay looks like after wards, lol, and hopefully no water got into connectors or engine may stall out and not restart.

And in general you do gain a few horsepower as well.

Downside is, it is another electric motor so one more thing that can fail, like fuel pump or heater fan or shift motor or even IAC valve.
But fan clutch can fail as well.

 

I use mine for DD and its excellent especially when towing in the summer in Georgia. Lets it cool at stop lights because the fan can run faster than the engine speed. But as little as mine runs id bet the motor will last a good while and I'm very particular with maintenance and i keep a spare controller and a used fan in the basement for emergencies.

 

I live in Central Florida, and currently we are into our "Africa Hot" season! With the A/C on, the clutch fan engages more, as it's thermostat locks up more in the stop and go traffic. This is the "roar" I was refering to. In the early mornings, I never hear it, but on the afternoons during the stop/go traffic, with the A/C running, it's there.

I ran an e-fan setup in my old F150 years ago, and liked it, so this ranger is going to get one. Waiting on the Ron Francis AR-88 controller. Already have the Mark IV 2 speed fan.

 

Then your fan clutch is working properly. You just don't like the roar when it locks up. That is understandable.

An electric fan should help solve that problem. They tend to have a better fan design that is more quiet.

 

Yea, I was not doubting it's operating correctly, only the noise this thing makes when it does. I cannot recall my earlier owned trucks making such a noise. I'm guessing because this ranger is smaller, and the engine compartment is closer to the cab then the full size trucks I've owned, making the clutch fan more noticeable I suppose.

Since I already had the spare Mark IV 2 speed fan laying around, and some spare time and cash, I figured buying a controller and installing the e-fan would gain me some quiet, less drag on the newly installed water pump, and a miniscual increase in MPG (any bit helps with this thirsty engine).

Overall, I do like this truck. It's the first small one I've owned, and am really impressed with it.
