4.0 fan clutch replacement??
Can I get some help with this?
I've been noticing this really annoying sound coming from my fan I am told it is the fan clutch and I'm going to reLace that and the fan... I was wondering instead of buying factory parts can I upgrade them to get better performance or is it not worth it???

The factory uses up some horsepower to run since it's always being turned when the engine is running.. The electric warms up quicker, runs only when it's turned on. The less accessories the engine runs, the more you free up in power/mileage. That's why most cars have switched to electric fans.

Don't forget that you are putting a load on the alt, which in turn robs the engine of power. Which is greater (more draw from the alt or mechanical clutch) I have no idea.

You can get a fan switch the turns on 10-15 degrees after the thermostat opens and turns off right around when the thermostat would start closing again. So, if you have the factory thermo, they can open somewhere between 192-197, get a switch that turns on around 200-205. That way it will regulate and won't stay on all the time or run too hot. For the most part it will run while you sit in traffic. It will cool enough on it's own while you are driving. Also, get one that has the a/c option. That will turn it on anytime the a/c compressor is engaged or it won't cool. Find a 16" fan that is at least 2000 cfm and higher. The higher the better, it'll cool better. Zirgo makes some decent fans for the price/cfm rating. 3000 cfm for around $100.

There's usually a temp sensor that turns it off and on, others also wire in a manual switch( good for water crossings if you offroad).

Yeah, you'll remove the fan/clutch and shroud. I bought an aluminum shroud from Jegs and modified it to fit the radiator and mounted it. Some people just mount the fan without a shroud and it works well but I have the supercharger so I wanted it to be more efficient. I was going to post a pic but I guess I deleted it from my computer. I suggest get some mounting straps to mount the fan and not use the plastic rods that mount through the radiator. The plastic rods can wear a hole in the radiator and are a pain if you have to service/remove and replace the fan.
