  • hi, i also had exactly same problem. at first, i had a coolant leak somewhere, then i decided to use those sealant, then the problem gone away, immediately after that, my oil pressure start dropping to 0 psi upon warming up. have you figured this out by any chance?
  • i'm having exactly same problem on 2001 grand cherokee limited I6. searched on the internet for months, and still havn't found anyone that claims a definite solution. since money is really the issue, i really dont' want to replace oil pump, oil pressure sending unit, etc etc until i can be sure it's really the cause. before the oil pressure problem popped out, i had a coolant leaking issue, i fixed it by dumping some stop leaking sealant, then the coolant leaking problem is gone, but oil pressure drop to 0 problem came immediately after that. i found some other people also had coolant leaking problem prior to the pressure problem. my guess is the coolant leaking and oil pressure dropping are related. i'm not familiar with the mechanical details, but could somehow the coolant leaking hole is connected to the engine oil tunnel? such that the nasty "stop leaking sealant" product flow into the engine oil tunnel and causing the oil pressure sensor to read low? this is such a painful experience, could someone give some advice?
  • Stop leak is nothing but a band aid on an artery. Just covers the underlying problem and does nothing to fix it. (not trying to be a jerk) Sounds as though you may have a blown head gasket. Do you have milky oil? :shades:
  • there's no milky oil, engine oil looks normal. i'm so stressed out about it driving to work every day... help!

    go and get a oil pressure gage from auto zone pep boys etc
    install it with a line to read pressures (gage is mechanical so tells you exact oil pressure ) run engine see what oil pressure is if stays up sending unit is bad if falls off oil pump is bad

    Is it possible to have a blown head gasket if oil is clean and not loosing any coolant any where. On a 2000 JGC 4.7 engine have milky oil in the oil cap only.Replaced oil cap and o-ring. Replaced PCV and hose. At first thought was a head gasket but not showing any of the signs. Do have a little smell of coolant in cabin. Rad is full. Oil is clean. I thank that some how steam is getting there and doing this not sure though.Thanks
  • Because of heat/cold, it's possible that it may just be condensation on the cap.I have seen this happen on other vehicles. A coolant smell (sweet smell) in the passenger cabin probably means a small leak on the heater core.Keep an eye on your coolant levels and your oil. Does your exhaust smell like antifreeze? A blown head gasket doesn't always allow coolant to mix with oil, it may be forced into the cylinder and burned with the fuel. Good luck! :shades:

    i have replaced my battery and alternator and still my battery keeps going dead. What can cause the battery not to charge right.

    First I had an alternator that was over charging up to 19. I replaced it then went back to auto zone had them check the battery and alternator again. My battery was junk so I replaced it right there at the store Had them run a check and the alternator tested bad. So I then replaced the alternator again making sure we checked to make sure it was good before I took it home. Now I should have a good battery and alternator. However after replacing the alternator again. I started up the jeep and let it run. Well it died and couldn't restart it. The battery was dead. I hooked up a battery charger and let it charge. After the battery was charged. I ran my jeep only to have the battery light come on again and the battery to keep draining.

    What can be going on here?

    You have to pull the steering wheel and tighten the bolts inside. Chilton shows you how.

    Check the ground. Sounds like you have a bad one.
  • paulepaule Posts: 382
    I concur with believing this is a ground issue. Trace your ground cable from the battery to the sheet metal where it attaches. Remove the bolt, grind the sheet metal until you have bare metal, reattach the ground wire and spray the bare metal with a clear corrosion spray.

    Also check/clean the ground from the engine block to the body.

    It may look perfectly fine but it most likely isn't. You cannot tell a corroded ground by just looking at the cable.
  • When I attempt using the a/c, it barely cools and the compressor clutch chatters. Why?
  • Is it difficult to change the right rear axle seal on my 2002 GC? Its leaking...
  • paulepaule Posts: 382
    My best guess is the bearings in the compressor are going bad. Also, check the belt.
  • paulepaule Posts: 382
    Not sure about the '02 but those are typically a little more than the average backyard mechanic will want to attempt. I'd do a google search on it. Odds are someone has done them and has photos of the procedure.

  • I have an 01 sport with I6 motor. My a/c will cycle for about ten to fifteen min the the compressor will stop working. Have had pressures checked and was told that the oriface tube was clogged up. Also I have changed the coolant fan radiator switch on the high side because the electric fan doesnt work with the a/c. I know switch is used for telling ecm when pressure is too high, but that is not the problem, ecm is not telling fan to engage. Could this be a R134 flow problem? Dont want to throw money at this problem, could be costly.

    I was just curious to see if this problem was resolved. My daughter's '94 jeep cherokee has the exact same problem except that now after restarting, the problem still exists. I did find that if I turn the ignition back to acc., everything works. Heater, wipers etc.. Appreciate any help.

    Just picked up my new cherokee, great riding suv. Went to put my child seat in rear and had problems with headrest. Anyone know how to remove or raise the rear head rest so car seat is flush with back of seat. Car seat is leaning on headrest, feels sturdy but there has to be a way to remove. All suggestions aprreciated thanks
  • loosenutloosenut Posts: 165
    my-98 gcl has a "collar" around the two steel posts..
    one has a "taper" kindaymbol on it..turn that one-(clockwise?) and pull the headrest out... then when you want to fold th rear seatsfor cargo,you'll find the same buttons that hold the rest-so yaon't loose it-on the bottom seat-flipped up!

    All of a sudden, after leaving a fillup at gas station and entering highway, my Jeep started jerking repeatedly, evenly, between 45 - 65 mph. It has never done this before. I could keep up with the flow of traffic. After an hour on the road trying to get home, I pulled off an exit and stopped at sign. The motor died, and Jeep will not start even though battery turns over. I had it towed home. About 4 months ago, Walmart would not change the oil; man said he heard a noise in the engine. A Napa station I regularly go to did change oil. A neighbor says sometimes the sensors do not communicate correctly, and this happens. Any ideas? This is a 5 speed, 4 wheel drive Jeep.

    I own a 93 JCS as well and have to replace blower motor. I do know that you may not need a switch because the "resistor" is what slows the voltage down to allow your blower motor to run at lower speeds that high. So more than likely just replace resistor for bout $15 bucks and should fix the switch problem!
  • 2002 Grand Cherokee Loredo 4.0 Engine. I am going nuts as well just trying to replace the spark plugs. I am an ole mechanic from the 50's-60's and the stuff that is on the engine does not make the identification of location or proper removal readily identifiable. Looking from the front to the back of the vehicle, are the plugs on the left or the right?
    The left has some sort of bar with additional 4 extrusions that are long enough for two spark plugs. This bar has several bolts heads that would appear to be holding it in place. Is this where the spark plugs are located?
    The electronic ignition has really small wires in a harness that runs behind the oil stick and lays against the block. What I cannot see is whether or not those wires go up to and through the bar on the left or to the conduit bar on the right. Very confusing.
    Anyone know where I can find a schematic to the 4.0 Liter Engine?

    sounds like the electrical ignition switch to me..
    take a simple circut tester,with a light,and pull the cover plate just behind the steering wheel,to expose the wires..three t-20? screws hold it on..
    i.installed a remote start this way,and there is one wire that suplies all those things you describe,the other is to run the engine..
    i suggest first finding the offending circut by turning it to acc-finding if it works on "on" as well,if not,the contact in the switch is bad..try to clean it with wd-40,but odds are,you're gonna have to replace it...my hillbilly side would try a toggle switch-branched from a switched(one that goes off with the key),cause if you go from a always live switch,you'll probably do what i'd do,and forget it-just once-and come out to a dead battery ! ! good luck!

  • i have a 1993 Cherokee with a auto in it with the 4.0 high output 6. i also have a 1990 Cherokee with a auto and the 4.0 inline 6. but not the high output its got the old computer in it. what i want to know is i want to put the motor from the 93 into the 90 will the computer harness from the 93 plug into the firewall and work in the 90 Cherokee? so basically i need to know can i put a motor and computer from a 93 into 90 jeep and just plug and play?
  • Hauling that heavy of a load and driving so fast and kicking it down to pass cars is whats doing that. I have a 1994 Jeep Grand Cherokee Limited with a 318 and i have changed everything you have except for the clutch fan and mine does just fine. It gets hotter than normal when my other half has me haul more than its made to haul. But I baby mine. The fastest I had it was 65mph on the highway which is the speed limit. Mine has 209,495miles on it and still going strong. But I don't drive it hard or hot rod it like your saying your other half does. Hope this helps you out. :D
