Re: 1999 Venture 3.4l Engine Exchange

I used a two ton engine hoist to lift the van off of the sub frame. I let the sub frame rest on a floor dolly (the subframe weighs about a thousand pounds).
You need to remove the fans and radiator. Unbolt the compressor and starter and move them aside. Remove the front engine mounts. Disconnect and label the wiring harnesses (3 of them). Remove the transmission lines from the transmission. Remove ground wires that are bolted onto the transmission bell housing bolts (front drivers side).
If the engine is not locked up, remove the three bolts that join the flywheel and torque converter. You can get to them once you remove the starter. If your engine is locked up, wait until your remove the subframe.
Make sure your wheels are pointed straight and remove the front wheels. Disconnect the calipers and put them aside. Unplug the ABS wiring connector. Unbolt the two large strut bolts that connects the strut to the spindle.
Rest the subframe on the dolly and remove the FOUR subframe bolts. Once you remove them, you can raise the van up and off the subframe.
If your engine is locked, remove all of the spark plugs and see if it will turn. One cylinder on the compression stroke can lock up an engine. If your cam shaft broke, you could have a cylinder locked on the compression stroke. Do not worry! You can remove the engine with the torque converter attached.
Once you unbolt the transmission bolts and the passenger side engine mount bolts, the engine should come up and out of the subframe.
I believe that is it. I hope this is not too long.
I used a white-out pen to label my electrical connections (it dries really fast) and I put all of my bolts and small parts in sandwich bags and labeled them with a magic marker. If I think of anything else, I will let you know.
