300E Engine Removal

I've been looking all over the internet for something that would tell me how to do this. I haven't been very successful so I'm asking anyone at this forum if they can point me in the right direction. I want to remove my 300E engine and replace it with another 300E engine. I just don't know where to start and what bolts to loosen. Anything would help me immensely. Thanks

Have you ever picked a motor before? Its a pretty big job for a first timer.

Above ground.....
You first need to go around all sides of the motor, and disconnect fuel lines, power steering hoses, engine harness, remove fan clutch etc, etc. Unbolt transmission dipstick from cyl head and detach kickdown cable from linkage. Also the throttle cable needs to be removed. Then, either recover the freon, or remove the a/c compressor and let it hang with manifold hoses attached.

Remove all bolts around transmission bell housing. DON'T FORGET THE TORQUE CONVERTER BOLTS!!!!! Remove engine mount bolts.

Go back up top, and visually make sure you are free everywhere, then put a block behind the tire, and get to picking! You may have to roll car backwards a little bit as you lift the engine out. JUST BE CAREFUL!! Make sure you have a helper with you

Tip..... the front of the transmission will want to fall down when you separate from the motor. Have a block of wood, or some long bolts handy, and you can let the bell housing rest on your steering links.

Have fun
