some additional information for you would be 'do it yourselfers'. Yeah, it's not a bad job but there are a few 'tricks' that I haven't found anyone mentioning before.
This is on a 2002 liberty, 3.7, towing with A/C (did they all come with AC??)
First. You will want to remove the front grill. Just 4 torx bolts on the top. The bottoms just kind of clip in. A little wrangling to get it around the headlights but it comes out. Put it in a safe place, you don't want to step on it.
As mention in other threads, the radiator support is held on with 4 bolts on the top. The other two bolts are close to the bumper. Some folks drill out the rivits near the top of the support (I did) but I did this before I figured out how easy it is to remove the front grill.
I have the towing package. I was able to do this without removing the mechanical fan.
I read somewhere you don't have to remove the electric fan/shroud. I just don't see how that would work but it might. It's easy to remove even with the mechanical fan. Two bolts, one connector and a little bit of a puzzle to get it out.
There are two bolts that hold both the radiator and the condensor in place. Easy to see. Easy to remove. The condensor is now able to move around a little bit but there are a couple of tabs near the bottom that actually slip into part of the actual radiator. You need to free the condensor from these tabs before you can remove the radiator. You can tell this was made for ease of 'quick assembly' at the factory but not so much for service. There are a couple of soft rubber like pieces that help make sure the air is pulled in past the radiator. Mine kind of blocked me from being able to lift up the condensor. A little bit off work and some slight trimming of the rubber type stuff and I was able to get it out of the brackets.
On my early 2002 liberty I also had two additional bolts that ran from the front to the back. These are not easy to see initially. They go through a couple of rubber insulators but are hidden by the fore mentioned rubber like pieces. To get to them you have to pull the rubber like pieces (RLP from now on) plastic tabs. There are three on each side. They come out. I mangled the crap out of the one that is just behind the bumper and didn't even bother to put it back.
On the driver side you will need to unbolt the aux cooler to get the RLP out of the way. The RLP also has some square holes in it where the condensor mounts are. You need to move these off of the tabs on the radiator or they will hang up on you as you try to pull it out.
So once you the the RLP out of the way you will see two more bolts with some very large washers that go through the the rubber insulators. Remove these.
Then the hoses, the transmission lines and the overflowl. The slide it out. There are a couple of plastic pieces o the bottom of the tanks. Maybe it doesn't just 'slide right out' but at this point you should be able to coax it out of its mount.
Intallation is the other way. Get all 4 of the radiator bolt started first. Then put on the hoses and trans lines. THen tighten down the radiator bolts and then the trans lines and upper/lower rad hose.
Here are some pics:
Here is the tab on the bottom of the radiator. There is one on each side. The rubber comes out with the radiator so move it to the new one.
Here is a shot of where the rubber goes into. Slips right into place no issues.
This is the insulator. It has a bolt that goes through it. You can't see it without pushig the RLP out of the way.
And a shot of the insulator where it is mounted. No bolt. RLP moved out of the way.
You can see the plastic tabs that hold the RLP and the hole that the top one goes in. You can also see the aux cooler. You have to unbolt it but you don't have to remove it.
