#1963 of 2589 Jeep 1993 - jsut purchaced quit running
May 06, 2006 (4:42 pm)
We just purchased a used 1993 Cherokee with 162K miles. It had been sitting for about a year, but was run every day before that. The oil had recently been changed and they charged up the battery before we took the car. On the way home we noticed a loud ticking from the engine after it really heated up well. Originally I thought they might have left some oil out, but it checked full and clean. I was teaching my son to drive the stick when it started having trouble starting after he inevitably stalled it a couple of times. Need less to say it finally quit for good just down the street from our house.
So far I have charged the battery, then replaced it. I recrimped the battery cable and have checked the voltage at the battery, fuse box, and alternator. It all looks fine. The car does not want to turn over at all. The battery cable wire get really hot when we try.
What should we look at next. Any advise/diagnosis would be greatly appreciated.

Here's some info from
"The transfer cases used are all chain driven with aluminum housings. NP stands for "New Process" which is the brand, if you will. The newer ones are NV instead which stands for "New Venture". It is the same transfer case just a different name.
NP207 - "Command-Trac" part-time only - 2.61:1 ratio low range - used 84-87
NP231 - "Command-Trac" part-time only - 2.72:1 ratio low range - shift pattern 2H - 4H - N - 4L - used 87-01
NP228/NP229 - "Selec-Trac" - 4Hi(full-time) - N - 4Lo (part-time) - used 84-87
NP242 - "Selec-Trac" part-time OR full-time - 2.72:1 ratio low range - shift pattern 2wd - 4part-time - 4full-time - N - 4LO - used 87-01"
If you want to use 4WD on dry hard surfaces, I think you want Select-Trac. You probably can find more info on the each at that site.

When you hit the starter, does it make any noise at all??? Can you physically turn the motor over by hand?? What was the oil pressure running prior to this?
Just off the top, I'd look at either a jambed up/locked up starter motor or a locked up engine. You should be able to put a socket and rachet wrench on the harmonic balancer bolt and rotate the engine fairly easily. The harmonic balancer is the large belt pulley on the bottom of the engine.
#1966 of 2589 AC not working
May 08, 2006 (4:52 pm)
I have a 2001 Cherokee Sport 4X4 and the AC stopped working. It blows luke warm air. I checked all the fuses and they are good. I am told the next logical step is to recharge it with a can of R-134a. Here's my problem. I don't know a whole lot about vehicles. I have the can to recharge with but I can't locate the exact spot where it goes. Can anyone tell me where the service port is and what it looks like? Thanks.

Well the saga continues. After replacing the battery and rewiring the wires at the terminal we finally have the car running. Not running well, but running. The starter seems ok, the alternator is putting out juice. The car is not over heating. It just runs really bad. We have replaced the spark plugs, new cap, new rotor. It is running very bad when it heats up. The engine still makes a lot of clacking noise from the rockers. The oil light comes on intermittantly ... It's off during idle, then comes on when we shift into 1st gear. I have given up on the home mechanic portion and taken to an expert. I'm still interested in hearing ideas, so that the shop doesn't take all of my money.

Chapter 4: We had the car towed to the mechanic. Yep - blown #2 cylinder. Needs a new engine. Next question is we are $2000 USD into this adventure. Do we put a new engine into it or get out now and sell it for parts? What do you think we could get for a 1993 Jeep Cherokee with a blown engine? What and where can I get the best price on a new/used engine?

Probably worn valve stem guides/seals. It's not a terribly expensive job to have done. If the shop uses compressed air to hold each valve in place, then all they have to remove is the valve cover, rocker arms and valve springs.

I don't know, what condition is the Jeep in? Is it worth it to you to spend another $2,000 on it??? Professionally rebuilt engines can be purchased in the $1,500 and under range.
If the rest of the Jeep were in really good shape, I'd say go for it. But then I'm a Jeep nut, and I'd rebuild and replace the engine myself. And I'd also know the condition of the tranny and t-case. There are too many variables for me to tell you what to do.
If the rest of the Jeep is in good shape, and depending on the mileage and what other goodies are on it, someone would give you $750 to $1,000 for parts or to build it up as a trail rig. If it's beat all to heck and has a ton of miles on it, then you might be stuck.

Before you try this... you can visually check the charge by looking at through the sight glass (I believe it's below the compressor). With engine warm, turn A/C on, adjust to coldest setting and fan on highest speed. Keep doors open so A/C system doesn't cycle on/off. Let run a few minutes making sure the compressor stays engaged. Look in the sight glass. If refrigerant looks foamy or has bubbles, it is low. Also, at the compressor, the larger line should be cool and the smaller line should be warm. I'll go look at my '99 to find the charge port, may be same as '01. Keep in mind that if you need to add refrigerant, there is a leak that will need repair.
