I have a (as said in title) 1997 Jeep Grand Cherokee Laredo 4.0L that I’m going for a more of a street look to it and I was hoping for some pointers on the largest tire size(all terrains) I can put on it with 17 inch rims and absolutely no lift. Im okay with slight rubbing on the well on turns.

I just recently picked up a 2000 Cherokee Sport 4.0 for free. However, there are issues with the engine. It starts up fine, but after only a few minutes the engine starts to overheat. The guy who owned it before me just recently took it on a trip from NJ to Maine and told me he had to make...

I just replaced the exhaust manifold on my 99 XJ, 4.0L. I installed a new gasket as well. When I try and start it, it goes full throttle and I have to switch the key back off. I have reviewed every wire and hose location. I need some suggestions.

I have a 1987 cherokee pioneer w/ 4.0 ac 4x4 4 door wagon that I removed the engine and front end down to the frame, cleaned and painted everything, then put back together. I have (3) brackets (see photos) that I cannot seem to identify or locate what they are for or what they do. I got the...

I recently blew my head gasket, radiator, and thermostat. I don't want to replace the gasket and have the bottom end go out on me, so I am on the hunt for a replacement motor. I would love some more power so I am considering a stroker or a beefed up 4.0L. I'd love to throw a 350 and a manual...

I have a 98 xj with a straight six. When ever I let up on the gas pedal I hear a high pitch whining. As soon as I hit the has even in the slightest it goes away. I did just have a new exhaust system put in so its actually a lot quieter so I dont know if it was there before as well. Any...

My 97 TJ finally took a dump. The 4.0 L engine started to get a ticking noise and we looked into what it might be and could not figure it out. When we did find out what the problem was it was too late. We had driven it across town and it started to over heat really quickly so we shut it off, I...

I have a 1989 Comanche and I having a issue with my truck "studdering". It is not backfiring or anything like that and happens at idle and constant speeds. I also have noticed it happens when it is warmer outside. Im not sure if it is a CPS or mabye a ECU? I did a tune-up 18,000 miles ago...

I have a 2006 4.0 TJ. Recently my check engine light came on and now I have problems revving past 2450 rpms. Usually this happens after the engine has warmed up and I have driven a few miles. It doesn't matter if the jeep is moving or not, or what gear it is in. If the engine goes past 2450rpms...

Hey, was wondering if replacing the head and upper seals, rings, gaskets would be considered a minor rebuild? Or am I just wasting my time without getting new pistons and cylinders re-bored? It's a 4.0L with 300+km.. Cheers, hope everyone's well!

Hello I have a 1997 4.0 Sport. It sat for four days, and then this morning would not start at all. It sounds like it wants to turn over, and comes close, but nothing. A friend came over and tried helping, but it is a little dark out already, he will check it out again over the weekend. I can...

Gentle people, I'm working with a 1987 Cherokee Laredo 4.0L inline-6 that has a repeatable, distinct problem of cutting off at 150 degrees and not starting until below 100 degrees. It cuts off immediately. No cough, no sputter. Turns over fine, not ignition. Replaced coil, rotor, dist cap...
