    There was a leak in the radiator of our 2001 Jeep Cherokee Sport, so my son replaced it. He also replaced the upper and lower rad hoses as "insurance." The upper one was clogged with rust. Now he needs to know the location of the bleeder screw to finish up. This is an in-line six, with Auto transmission.
    Many thanks
  • I hope someone here can give me some advice. I know NOTHING about car mechanics and I'm sick of car repairmen (and salesmen) cheating me.

    I bought a 2000 Jeep Cherokee Sport with 45k mile (yes, that's right) three days ago. Had them change the timing belt at the dealer before I took it. Have driven it 200 miles. Pulled in the driveway just now and fluid (I think it is coolant) pouring out from under the front.

    Of course, dealer now closed and I'm without a car until Monday or Tuesday.

    Any ideas would be helpful. I've read on other sites that the water pump should have been changed when they changed the timing belt. Would that cause all the fluids to pour out?

    HELP! :cry:
  • The best thing to do is call the dealer that installed the timing chain maybe they damaged the raditor when the were working on the front of the engine. Either way it sounds like a dealer screw up and they should take care of it for you.

    Never overheated before replacing with new radiator (old was leaking) and new thermostat. I was told about air pockets so I install Prestone Reverse Flush Kit. Did not work. Changed the cap to higher pressure but it still filled the tank.

    Don't know what else to do besides the water pump. But either it works or don't...doesn't it? I don't want to remove the pump only to find nothing's wrong with it. Should I replace the pump or should I donate the truck.

    Not sure if you'll recieve this as it is an older post, but the only info i have for you is not much i'm in the same boat, my 2002 jeep GC laredo does the EXACTTT same thing, there was a recall on the radiator fan because they were basically chit, but once it blows out, your radiator fan relays blows out as well, this has happened to me the past 4 yrs all in june or july, and every year they replace the fan for free since it was an inital recall but it costs me 340 out of pocket for the relay that it blows out, alos i get the exact same message about coolant low and yadda yadda, i have no idea about that, i keep a full bottle of coolant in the jeep along with a jug of water at all times because honestly i have no idea when its going to happen so i take no chances, however if you do get this and have any other further knowledge on this problem let me know would ya, thanks.

    :confuse: my jeep has started overheating about two weeks ago, the cooling fan is running, i have canged the thermostat and flush the cooling system, it only overheats when i sit for long periods,while im driving its fine.Whats wrong
  • Ok So far I still can't figure it out. I changed the relay behind the headlight to find out the one I bought is bad. So I put my old one back in (because the over heating problem is intermittent most of the time until recently)and of course the fan is spinning. But the temp is still going past 210. Tried the laser idea ,and If I point it at the fan it will hold a continuous dot form the laser in a still position(if that makes sense) so what else can I do or need to resolve the over heating problem?

    if over heating is intermitant the fan could still be bad and not running up to speed could still turn but not fast enought to cool raddiator

    I wish i had more info for you, it took me 3 weeks just to get an appointment at the jeep dealership to have my radiator fan and relay replaced (for the 4th continuous yr in a row) and when i got there i told them to come up with a legit reason why this happens every year but then they told me they needed to keep the jeep for 3 days to do a 4 hr job because they were backed up so i just said screw it and left as the jeep is my only vehicle but i swear if i find out why jeeps are so [non-permissible content removed] and constantly have these over heating problems i will post the solution as soon as possible
  • Sounds like my jeep had a leak in the radiator,changed water pump,changed radiator, changed thermostat, and had radaitor cap checked. Bleed cooling system. Still ran hot. Removed thermostat still ran hot, The temp sensor was not completely bad, but it was reading off. My jeep was running 212. Changed senor runs 204 now. Also check and make sure your cooling system holds the correct pressure. If it was ran low on fluid it could of damaged your water pump.

    has probly installed the belt wrong as the water pump turns bacword on the l 6 engine take it back and have them make sure that the belt is installed right
  • I had my cooling fan on my 2000 JGC Laredo 3 times and it just went out again. It is fine when I drive, but when sit idle too long it over heats. What gives? got any suggestions for the underlying problem and how to fix t.
  • Hey there starz8235 I have a solution but i'm not going to guarantee you 100 percent this is the correct answer but i will tell you it's what happened in my situation. I live in las vegas and the for the past 4 yrs my radiator fan has blown out and in return so has my radiator fan relay in my 02 JGC laredo. Every yr i bring it into the same jeep dealership and every yr they replace the fan for free but i pay 340 out of pocket for the relay since the fan itself was originally a recall but not the relay so i get stuck there. I consider myself lucky when it happened this past june. I brought it into the shop but they were so backed up they said they needed to keep the jeep for 3 days and i said screw that, so i went to some rinky dink auto shop and found AN HONEST MECHANIC if you can believe that.

    He told me the fan was perfectly fine as well as the relay, (which the jeep dealership would never tell me, and it was the exact same problem for the past 4 yrs with my jeep overheating.) He said the problem was in my electrical motherboard or something like that. He said it the electrical system just wasn't working properly which made it to where my fan wouldn't run right. For 100.00 he connected my fan to the battery (i believe) so that the second my jeep turned on the fan started right away. I've never had an issue with the overheating ONCE since he did that. Now i'm not stating it's the perfect solution for the long run, but if your short on money i'd suggest looking into it as a short time fix. Down here in vegas it will stay hot until mid to late oct so this was the perfect solution for me until i can get the money to fix the main problem. Personal opinion i love my jeep but i think i heard it best from 1 person, with a jeep you either get a real winner or you get a lemon. As i've stated i've had issues with the radiator fan, which i now feel was unjust. All of the window regulators have went out and i've had to replace them all, the power seat on the driver side has had issues with 2 of the buttons, Check ignition light comes on for no reason when it wants to, sometimes it stays on for days, to weeks and then for no reason like putting 5 dollars in gas in it when its 3/4 filled already it goes away all of a sudden lol, it shutters when your stopped at a stop light like it wants to die, and like most jeeps once you get it up to 60 or higher mph it vibrates and hums like crazy. Sorry for long response, i hope this may have helped in some way.... Doug
  • I guess i honestly couldn't tell you the reason jeeps seem to have this problem, either its just coincidence amongst millions of us, or i'd seriously ask someone to look at the electrical situation and see if that's not the real problem as it seems to be in my situation.
  • it is kind of strange because there is just a ground and power wire going to the fan. Thinking it may be the fan motor itself. Jeeps are nice, but now after seeing all these problems I am thinking it may be time to get rid of it
  • You and me both brother... as much as i like my jeep as well, it just has way to many problems, and last night while driving home from the store i noticed something for the 1st time i've never noticed... the interior on the roof is supposed to be a grayish / cream color, and when i looked up it has brown spots and large brown circles all over it ????? It has never been smoked in or had any water damage at all, so i'm really intrigued by this new situation. Yeah but about the fan problem i really have no idea what the mechanic did, i'm not a "mechanical person" all i know is he rigged up my fan to where the second my jeep turns on the fan turns on automatically?
  • Wondering if there's a way to access the fan relay without dropping the entire front bumper? Can you cut a hole somewhere behind the headlight area? I have the fan jumpered right now. Its always on... I'd really like to do it right but last time the relay died it cost me $600/labor the part is only about $28.... Any tips about getting to that relay? Thanks
  • hi how does the joins come apart on the condenser pipes can any body help so i can replce the condenser and rad.thanks
  • I don't know anything about cars so please help!

    My 01' JC has 82,000 miles. All winter the heat would not work and it was leaking coolant and the check engine light would go on and off.

    Two weeks ago I had a new radiator and thermostat installed and a new belt (something to do with the alternator) installed. When I picked up the car, I drove it around for about 30 minutes and the heat worked fine and the check engine light did not come back on. The next morning, it had leaked reddish fluid and when I started the engine there was a loud screeching noise. I went back to the shop and they suggested I drive it for a few days and see what happens. The leak stopped that day. But, the screeching got worst... now, I hear it every time I start the engine, when I turn on the heat/air, when making turns and even sitting at stop lights! I never had this problem before.

    I'm taking it back tomorrow so any suggestions would be helpful because I don't trust the mechanic! :sick:

    Thanks!

    May be completely unrelated problem. I had the same issue(s) with mine. Turned out to be low power steering fluid. Will make you engine sound like a jet when it is cold outside. May not be your problem but it is an easy thing to rule out.
