Howdy - Just wanted to post that if you run through some mud and you start getting a cycling vibration, check out your cooling fan. It seems like it doesn't take much mud on that thing to unbalance it enough to create a pretty disturbing vibration. A quick hose-off resolves the issue. Concerned me at first, until I figured out what it was

Great tip! Thanks.

if you are really good at getting it muddy a hose wont be enough, you may have to clean each blade off with rags, been there

Well I don't have a viberation, my fan is just not working! Went out wheelin today and on the way out my temp gauge started spiking the red line. Once I got engine cooled off we were able to get home but fan still isn't working:(. Any suggestions?

Mine died at 30,000!
I have replaced it with a SPAL sealed electric fan, 1000x better at cooling. Simple to wire it up to the factory plug.
You can mount it in the OEM shroud with some trimming and a handful of homemade mounting brackets.

thanks. upon further investigation i was able to bump the fan directly from the battery, but only once also i was not able to read a voltage thru the wiring. fuse is good, are there any sensors that people have had trouble with after getting a little wet?
