They typically come out the bottom. once everything is ready to remove the engine, unbolt the sub frame and roll it out from underneath.
If you take it out the front you have to cut out the radiator support and then either weld it back in or get or fab up a bolt on tab system to reinstall it.

Thanks for the reply. When you say subframe what are you referring to? This is a driveway project using floor jacks and stands.

Here is an example of how the subframe slides out ,,I have a pic of how to remove from front , just cant find it at the moment , it is actually easier to remove the subframe and it makes for a roll around cart till you put it back on the van , there is a nice pic of a late model Ben2 with body raised up on the site , don't recall which thread though

That looks like a driveway project to ;)

I've seen the van lifted with an engine hoist to.

Compared to weaseling it out, getting hung up on something, smashing your hand trying to keep the motor or tranz from smashing something else.. :lol:

Because of the core support being a solid piece, out the bottom the way,on his year van.I pulled a 90 van engine out the front.It really has alot of room coming out.Actually comes out easier than pulling the engine and tranny,at the same time,than out of a normal car.Normal being engine actually under the hood.Chevelle,mustangs and the like.

Thanks for the comments but I am uncomfortable looking at that pic with the body raised and supported in an area doesn't seem to part of the main body support. Is that a safe place to hold all that weight?
What method is used to raise the body? Using jacks or engine hoist? Where is the lift points?
What need to be disconnected between the 2 halves.

Get under, over and around to see what stays with the body, and what needs disconnecting. Things should be pretty obvious, and then when you lift the body, most of the weight will be left sitting on

the ground. It is not as scary as you might think. Be sure to set the E-brake, and chock the rear tires. You will be able to see the areas that can be considered lift points if you look. I would suggest that

you get yourself a copy of Haynes, or Chiltons repair manual, or better yet, look on Ebay for a Factory Service Manual. It's mostly like learning to ride a bike, scary the first time...

Good luck

You would be much farther ahead to pull the motor out the front... It sounds to me like you don't have a lot of experience with this kind of work. If that's the case you probably don't have most of the tools required either. Leave the trans in the van and and use an engine lift plate bolted directly to an engine hoist to lift the engine up and out. Very simple.
Pulling the engine out the front does require cutting the upper radiator support but that is much easier than removing the entire sub. Disconnecting the steering and brakes. trans lines, drive shaft, shifter linkage, etc.

Hello there. I know this is an old post. But by any chance did you ever get to changing the engine? If so, did you have any problems when starting the new engine?
