Yea, yank it off and give it to me. I've never had one, the fan slings mud all over the place. If you have an open filter this is a problem. I had to build a shield for mine. I do kinda wish I had the splash guard, sometimes. It makes it a bitch to work on though, that is a fact.
BTW, my jeep eats alternators, probably due to mud and grit getting in them. I'm on my third one now.
I've been planning to make several mini splash guards, so as to protect stuff, and also allow work from below(which is important). However this will take a lot of trial and error. I'll post pics if I ever get around to making some. Has anyone else tried this?
