How do in know if my check engine light works? When I bought the jeep, the previous owner had cut the O2 sensor wires, I'm guessing because it's bad. Also exhaust is cracked all over. But anyways, wouldn't that make the check engine light come on if he did? My trans also slips at take off, getting a new one soon, but wouldn't that make check engine light come on? Is there a fuse or somthin that he pulled?
Anybody?

What do you guys run in your xjs for a electric fan swap? I'm currently running a right hand drive electric fan in place of my clutch fan but it's not cutting it over here in az in the summer... Any suggestions?

My first question is, Why do you want an electric fan instead of a clutch fan?

My second question is, there's several write ups on this topic and people say what they use. Did you look around at those yet?

Brake upgrades?
I was wondering what are some good brake upgrades you guys run? I'm running 32x11.5x15 Goodyear MTRKs on 15x8 w/4.5"bs steelies and I knew XJ brakes are crap to begin with and I'd have more rotational mass to stop, but I didn't think it would be that hard on my stopping distance. Really have to plan 3 or 4 cars ahead and almost rear ended someone who cut me off when slamming on the brakes. Right now I have stock drums, pads, and rotors (NAPA or CarQuest I think) that are about a year old now. I know about and plan to do either the ZJ rear disk mod, or if I'm lucky enough to find, do the KJ 8.25 disk mod because IIRC it's a direct bolt on to the XJ 8.25. Do you guys run preformance brakes setups? Drilled and slotted and all that, or just go bigger in size? Any other vehicle front brakes worth an upgrade from the XJs? I have V8 ZJ steering on mine as well.

Anybody want to give me a recommendation? I'm farting around with the idea of buying a crate motor (stock) and switching out mine.
My engine is 25 yrs old, is way up there in the miles, and leaks as much as you would expect of a 25 yr. old motor.
It quit running on me the other day, which I think was caused by the timing chain jumping a link. I've got a set of gears and the chain here because I was anticipating having the problem.
I'm pulling the front off today to check things out. But, the idea popped into my head that maybe it's time to drop a new engine in there.
Any comments on crate engines? Where to get one, and a ball park price?
Suggestions or comments are welcome.

Any junkyards down there? I was able to find a low-mileage 99 in a salvage warehouse for $500.
Otherwise they are all pretty much the same and the big question is who will give you the best warranty if there is a problem

An 09 XJ, huh? Idk what you drive, but I'll assume you got the year right. This section won't be of much help, we have other sections for other vehicles, WJ, KL, etc. that will be more specific.
