Clutch Fan

Should I keep the clutch fan or go with something else? If I go with something else any suggestions on fans would be great...
Thx

I gave my clutch up for a 575 Flex-A-Lite electric fan and have been very happy with my choice. I got mine off of Ebay for less than $200.

When I got my cj PO had taken off the clutch and put on the direct drive........ just don't do that to yours! My waterpump sings to me everytime I start it up. I'd replace the clutch or go electric..... great for water crossings!!

Maybe my clutch fan isn’t working right. Should the fan spin when its cold (starting up in the morning) My fan does… The longer I drive at highway speed the temp gauge keeps creeping higher. I have about a 15 mile commute to work and 10 of those miles are highway. I go about 60-70mph The only time I see my temp go up is those 10 mile on the highway.

it should spin slowly when cold and then as the thermostat in the clutch warms it should "catch up" to the water pump speed, if not it needs a new clutch...

How high does the temp go? I would keep the clutch fan. maybe the clutch just needs replacing.

I have the fan clutch test procedure in PDF file. I'll gladly email it to you if you pm me your email address.

The temp goes up to the middle between Cold & Hot then once I'm off the highway its goes back down closer to Cold mark

Its seems to spin at the same rate as the engine.

I wouldn't worry too much about that, my thermostat doesn't open till a little past that middle mark. If anything, your jeep might be running a little chilly.

What's the ambient temp during your drives?

I have a 180 degree thermostat in mine and the temp gauge sits constantly at slightly past center. I think you're in good shape assuming your temp gauge is operating properly (we're talking stock Jeep gauge). You might check your thermostat. Sounds like you may not have one, one that's stuck open or one that is set for too low a temperature.

I second that motion counselor... thermostat could be stuck or out, maybe a little flush and fill too.
