Still need to know which engine you have as the 4.0 and the 4.7 V8 are all different animals. the 4.7 is a Mercedes Design and the 4.0 is a american motors design . their all different. The 5.2 is the most common engine.is the 4.0 inline 6. the procedure is about the same for both. the flat rate manual allows for 6 hours to do the work. I have done the job a few times and I'm a chysler dealer mechanic. I take all day as the airconditioner needs to be recharged too and it's best to change the evaprator core while your in there as it fails more often than the heater core and if we're after the evaporater core we change the heater core as the labor job is the same. The first step is to remove the entire heater box from the car which requires removal of the steering collum and the dashboard assembly. The combination of things that need to be done requires you to be a master mechanic, as you get intoo all the systems of the car to complete the repair work. On a scale of 1-10 this is a 8 as for difficultly and theirs plenty of times you need a second person to hold and staey things and line things up. I remove the front seats too and if your a big guy you have too. I recomend that you spend the money at the local auto parts store for the car as thiers lots of hiddin bolts and safty precautions that had better be followed or your breackage rate of parts will be higher than if you paid the highest place in town thier highest rate and you'll still be working a very diffacult job. I expect that you local garage thart does this kind of work, ( dealer, Raditior shop, full line, auto service shop, some tire stores ( not all)) and even some of them don't have the mechanic that can do this work right. Your evacuating the air conditioning system and removing the lines and the epatorater blcokes, after that your draining the cooling system and removing the lines from the firewall and you'll need to be careful as the heater box is easy to damage. disconnect the two vacume harnesse that are under the hood these operations are best done with the hood removed. and with the hood out of the way it's easier to et the box back in when your ready to put the repaired bax back in the car. with the ateering collum disconnected from the bottom of the dash and set it in the front seat and the passengers seat removed from the car. remove all the bolts holding the dash in and pull it up and out. the instrument cluster has to be removed as do the heater controls and the radio just so you can get to all the bolts that hold the dash in, Disconnect the main wire harnesses and thwith the air bags removed the dash can be removed from the car.. on the engine side of the firewall theres 6 studs sticking though with nuts on them remove the nuts and the condesate drain hose. on the interior side pull back the carpet and remove the bolts holding the top and the bottom of the heater box to the friewall. slowly with a helper remove the heater box and watch for wires and hoses that you may have missed while you wer unhooking everthing, anything you don't wthink you'll remember how it goes you'll need to take pictures draw scheches and tag and number so you can put it back right. Remove the heater box and put it on your workbench being carefull not to drop it or break the little motors theat run the air doors the heater core comes out of the top of the box and the heater tubes are sucured to the heater core with brackets and they fit in the core it'self with O ring seals. put a little sealing grease on the O rings as you go back to gether and get the cre set in the box with the tubes hooked up and pressure test it for leakss before puting the heater box back in the car ( theirs nothing like having to do this job twice.) Change the evapater too as you don't want to do this job again soon, it comes out like the heater core only the tubes are made onto the core. With the box assembled and your helper ready put the box in and connect as many wires as you can as it goes in as there easier to connect with a litle room.. Hold the box carefully as a third person needs to be on the engine side to make sure to guild the pipes though the firewall and direct you to raise or lower the uhit to alline all the bots to thier hols as forcing anything may break the connection between the core and the hears pipes and your back to the beginning. as soon as the box is bolted up again pressure testr for leaks as it's bad to have to find out after you've put ht e dash all back in. connected the heater hoses and again test the whole cooling system. fill it and al. and test again as the teardawn if you have to is four hours shorter if you have to go back and do it over now. reinstall the dash and all the wiring and as it goes together its easier to aline the ducts as it goes to gether than to try to force then in later. connect the lines to the airconditioner and charge the AC unit and with everything hooked up run the car with the hood still out and the steering down and the seat still out checking for leaks. ( i've done this job 3 times after someone broke something doing it wrong the first time. I charge more too.) If your the master mechanic that yu need to be to do this job I don't know why your asking the way to do it on here. Shop around and if you can get a done job for less than $500 and they;ll warrentee all the systems disturbed to work correctly ( heating airconditioning steering seats hood radio all dash gauges shift indicator transmission function wipers turnsignals and all the other lights and the check engine light won't be on, go for it ) I've heard of this job going with extras at over $1000. If your not an experienced mechanic with a good experienced helper then you'll save money paying to have the job done.

I just replaced the engine on my 1995 Jeep Grand Cherokee Laredo. I replaced the V6 4.0 liter engine because of a blown radiator, although before removing the old engine I had the radiator replaced to help solve the problem. That fell through and the water pump needed replacing, after that didn't work "the rods over heated and were bent" is what I was told. Causing a complete overhaul and replacement of the entire engine. After the switch, I was able to drive for a short period of time. Since th

In my sons 1993 Jeep Grand Cherokee there was a dragging grinding sound coming from the passenger rear wheel when you stepped on the brakes. I pulled the drums off and the cylinder was leaking slightly and the brakes needed replaced. I replace the cylinder and the rear brakes. I then tried to bleed the new cylinder and I am getting no brake fluid out of the bleeder valve. I then pulled the line off at that wheel and still no fluid would come out when the peddle is depressed. Any thoughts on why


Hi,\015\012 Have your son pump the brake pedal until it gets hard. Then as you loosen the bleeder screw at that wheel tell him to let his foot ride the pedal and don't take his foot off until you tighten the bleeder screw.\015\012 You se ... 1996 Jeep Grand Cherokee

I have a 2000 Jeep grand Cherokee. Can the bearing and crank shaft be replaced without having to replace the entire motor? They are telling me I need a new motor, but when I told them i couldnt come up with the money, they suggested that maybe I just need to replace bearings and crank shaft. But.....before they were telling me I had some "metal shavings" in my motor now. There were some very tiny groves in the crank shaft. And the bearings were looked like they had burnt motor oil on them.


Yes the crankshaft and the main bearings can be replaced w/out changing out the motor. You can probably get a motor out of a wrecked Jeep and have it installed for under 1,000.00 and have it done quicker than replacing the crankshaft, and main bearin ... 2000 Jeep Grand Cherokee

I have a 1997 Jeep Grand Cherokee Laredo that the top hose that leads from the radiator to the thermostat blew the other day. I replaced the hose with no problems but the gauge in the jeep keeps indicating overheating and the code reader has a code that has the temp sensor error. This sensor which I found on the top of the thermostat top was wet inside from the coolant. Could this have shorted the sensor and does the thermostat need replacing as well?


Thermostats become unreliable and really should be replaced any time the engine overheats for any reason. After replacing it, fill the system using plain water (just in case it overheats again) and run it and check for problems If the sensor had cool ... 1997 Jeep Grand Cherokee
