Just kill the fan clutch and be done with it?

With the offroading environment in the Midwest, we're in a lot of mud and water. Not the best environment for radiators and fan clutches. I've lost 1 radiator, 2 fan clutches and 2 thermostats in the last year. Wondering if I should just put a spacer in place of the fan clutch and power the fan all the time? Since she's not a DD, mpg's are not my biggest concern. Overheating is a much larger issue.

Thoughts?

She's an around town and weekend toy as well as an offroading addiction. She has gone 150-200 miles to get to an off road park before, and will again.

Seems like a good situation for an electric fan

I know, but I have so many other things to sink that kind of money into. It's on the longer term list. If a $15 spacer will get me through until the fall/winter upgrade season, I'll be happy.

If you solid mount it, go with a plastic fan to keep the weight at high rpm spinning down. There are cheap ones like 20 bucks at parts store.

And carry a spare or two.

I can see where that would be a good idea. If I stay with the metal fan, and it gets caught on something on the trail, it could do a hell of a lot of internal engine damage before the blades rip off. With a plastic fan, the blades would crack "fairly" easily compared to the metal fan.

See? This is why we ask the questions. Sometimes the simplest thing (in the OP's mind), isn't so cut and dry.

The thing is, once you do that, THEN you upgrade to electric, that $15 you just spent on a spacer is money out the window.... put that $15 towards a Taurus (or comparable) fan from a u-pull and you won't have to put out much else.... depending on the yard, you MIGHT even get change BACK from that $15

The fans around here are $25-50, plus the relays, the wire, the temp probe, the time, etc. Add it all up and it's a $75-100 project plus a weekend's time.

While it's a project that's on the books, what I'm looking for here is --- does anyone run a traditional fan without the fan clutch? Does it work? What are the good sides and bad sides of doing this simple, 10 minute, change out?

Thanks.

I had my radiator come loose and the fan dug into it. Fan was fine, just needed to to shaved a little to get the rough spots out. Plus its SO LIGHT.

From the looks of it, I can get a NEW e-fan from RockAuto for about $100-115, including a unit that has a reversible fan on it so it doesn't have to be flipped over, etc. Personally, I'd feel much more comfortable putting in a new part than a part from a 150k+ mile vehicle that may die at any moment. Bone yards aren't exactly well known for testing and warrantying their parts. 10 minutes or 10 miles, whichever comes first, is the motto around here.

With what you have already spent in replacement parts, you could already have installed a brand new electric fan.

When running in mud and water you want for the fan to turn off so that it doesn't propel itself into the radiator. If you just yank out the fan clutch and replace it with a spacer, install a flex blade fan, (they are of a two-piece unit), one that the fan blades will flatten out if they ever come into contact with said mud and water.

But heck, with that kind of money do it right, I would follow the advice of these kind people by installing an electric fan from a Taurus and installing a remote fan switch to kill the power to the fan when you run through the heavy stuff.

Your sarcasm is not lost on me, but is always appreciated.

I know I'm looking to do things in a slightly unconventional way, that's why I'm asking the questions. When a buddy of mine and I were talking earlier today, he brought up the idea and it sounded intriguing so I figured I'd let nature run its course.

At this point, my only planned wheeling trips are local and at a private farm that won't have me out for very long, or long enough to make me overheat. I'm starting to lean into letting bygones be bygones and moving to the e-fan this fall.

As I indicated in a previous post, I can get a new e-fan from RockAuto for a respectable price (compared to local sources). I may read up some more, develop my plan, and just go down the e-fan route. It's just so d**n frustrating that she won't keep cool. She did fine for over a year, then after 1 specific trip she started running hot. Now no matter what I do, she won't settle down and play nice. Women.
