how to remove 3. 7l engine after evertything is disconnected

TwinDmax · **Posted:** Wed Jul 18, 2007 8:16 am

How do you guys mount a chain to this engine? I can bolt it on the front of the drivers side head or coolant gooseneck but where do you guys hook the chain in the back?

also, can anyone do a vin check? This is the jeep I purchased 1j4gl58k02w125566

If you go here you should be able to punch in the vin and look for recalls etc.

Whatever you do you don't want to tie that chain into one of the aluminum parts unless you have a manual saying that part can take the load, or it is a thru bolt going into the iron block. Why are you pulling the engine so soon?
If I remember right the carriage under the engine ties in the front end and the engine as a structural member of the frame and it can all drop out the bottom, I think the minivans and other rigs are also built that way.

From an '02 Manual
Step 29 : "Install Engine lift Plate "

I'm not having success extracting the picture of the lift plate. It looks like the type of rectangular plate that if it had a carburetor, it would bolt to the top of the manifold after the carburetor was removed.

#(29) Install engine lift plate.

Does this beast need a special plate?

most engines have a couple of spare bolt holes you can put in a long bolt and attach a chain

To hell with how to get the engine out, I just wanna know why he's pulling the engine. Is he rebuilding it or swapping something else in? Perhaps a HEMI? :twisted:

TwinDmax · **Posted:** Wed Jul 18, 2007 11:31 pm

The veh. was traded in at my dealership and I bought it for 1,350or so. It had a knocking sound so I bought a 39k salvaged engine for about 1,350. Since I spent so much time installing the twin turbos in my chevy truck I did not want to swap the engine myself. I hired one of my mechanics to change the engine. I went over to his place to see how everything was going and he said he was having troubles w/ taking out the engine/putting the new one in. Since I found out everything I know about diesels on the online forums I figured this was the place to go. As for this vehicle, it will be used as my wifes daily driver. Sorry guys, no hemi. I had to sell my 68(ragged out) drag car camaro for the truck I have. Only one play toy at a time, I am definately not rich like that.
This is the vin off of the engine I bought 1J4GK48K53W599589(03liberty). After pulling it last night the flywheel and valve covers were different. Is there anything else different?

You hired a mechanic who needed online forum help to pull an engine? :shock:

TwinDmax · **Posted:** Fri Jul 20, 2007 8:20 am

our used car mech. was having some questions when I went over to his house to check. I want to make sure it gets done right. By the time I gave him this information he already had the engine out. He used a head bolt on the d/s and wrapped a chain around the exhaust manifold. It sucks that you need a "lift removal plate" for an engine install.

If I find a mechanic who doesn't know more about pulling engines than L.O.S.T., you can hire him all you want and I'll laugh my booty off.

Glad he got it out with issues TwinDmax. Its never fun to drop an engine.

Make sure he's careful when he drops in the new one. The 5 star dealership bent the housing on my transmission when they dropped mine in.

minor issues...like the torque converter not fitting on the 02 w/ the 03 motor... I posted another topic to find out it I can use the 03converter w/ the 02 trans.

KY Liberty · **Joined:** Sat Jul 09, 2005 1:46 pm **Posts:** 1195

I believe the engine computer, transmission computer, throttle body, torque converter, and transmission are all different between the '02 and '03.

TwinDmax · **Posted:** Mon Jul 23, 2007 11:43 am

would that keep the swap from being compatible?

KY Liberty · **Joined:** Sat Jul 09, 2005 1:46 pm **Posts:** 1195

I think if you're just swapping the long block, and leaving everything else alone, that you might be OK. However, I'm a forensic computer analyst and systems engineer, not a mechanic. I have to hire mechanics to help me with the Jeep. Definately try to get some other opinions here.
