Hey, Randy
That adjuster knob you have is cool! That's an adjustable thermostat, I think ... and that means you can set your fan to turn on sooner, or later, depending on the temps you're reading. If your temps are reading too high before the fan comes on, you should be able to turn that knob and make the fan come on sooner, and keep your engine cooler. Or if the temps are reading too low, you can make the fan wait longer before it turns on. I plan on putting one of those in soon ... only I'm gonna install my adjustment knob in the cab where it's easier to regulate.
I've heard that electric fans are better than mechanical fans for cooling things down and the electric fan I have now sure is doing a better job than the mechanical fan I had before!
It may not matter much if you have a fan pulling or pushing, but I prefer a fan on the engine-side rather than in front of the radiator -- I think it'll turn on less when cruising if it isn't blocking the front of the radiator.
The only thing I don't like about them is that they draw so much juice!! When a 30 amp fan turns on, the initial kick is more like 60 amps! So it's VERY important that they are wired and GROUNDED properly! I'm gonna be rewiring my whole electric fan setup this weekend (and a few other things, like my headlights) -- the RIGHT way -- and I'll be posting all the info and pics at my sight by the early part of next week.
