All,

I recently purchased a 3800 swapped 88 Fiero and have had a string of issues. Most recent is the header exhaust has a big crack. I was told the entire engine/trans/axels can come out in about 2-hours. While I don't think it will be that fast, I'm a little worried about just disconnecting things without any procedures. Seen some posts on jacking and/or hoisting rear end, but not much on order of things to disconnect.

I am relatively handy, but no where near a professional mechanic. I am really good a following procedures (military background), so I was wondering if anyone has a "checklist" of the order of things to disconnect to pull the entire unit out?

Any help would be greatly appreciated so I can get my new prize on the road.

Thanks, Benjamin

I`m no expert but I have had mine out a few times and while some of the stuff you disconnect is mostly the same it really depends on
how the swap was done. Such as coils left on engine or remotely mounted. How the coolant lines were run. How the heater lines were run.
How the fuel lines were run.
I had never pulled a 3800 out of a car when I did mine but I just looked at how everything was run and made a note of it.
I`m sure some more experienced people will chime in.

This is for a duke, but TopNotch just did a writeup on dropping everything together.

You mentioned you are not a mechanic, and have never done this before. That being the case, you will have no way to tell one bolt apart from another by looking at them. Trust me, I know this

Buy your self a box of ziplock bags, and as you take bolts out, put them in groups in the bags and label them. It will take a few more minutes, but it is well worth it. Also, taking a TON of photos as you go along for reference to put things back together is also a good idea.

Simple answer; anything that is on the engine that attaches to anything else (not on the engine) must be disconnected. Things like water lines, trans lines(auto) , vacuum lines, fuel lines, wire harnesses , air intake pipe, battery cables/ground lines, brake calipers. eBrake cabes, throttle and transmission cables. Then you support the cradle, remove the six strut bolts, remove the four cradle bolts and drop the whole assembly down. Figure 6 hours of work for a first time attempt.

Taking pictures before you start removing things can help with hose and wire routing.

I know people say to place the 4X4 just in front of where the cradle is. But does anybody have any good pictures or at least an idea of what areas to avoid?

I know the width of the Fiero is a bit under 6ft. Do you need notches (never seen any in the pics that people use) for the scissor jack points? Don't want to bend anything. Is 8ft 4X4 a bit of an overkill sticking out the side a foot in each direction? Should it be shorter than 6ft?

I have everything disconnected from the engine, ready to unbolt the cradle, but securing exactly where the 4X4 is where I need some advise.

By all means keep track of where all the bolts go. When I pulled my V6 out of my 86 gt. I took a piece of cardboard , about 3 by 4 feet and punched a hole where every group of bolts went. Then drew a circle around that group and wrote what they were. All goes back together so quick. I used a Haynes Repair Manual for all my work. No internet back then. I just purchased a new manual off eBay for $18.00 shipped. Worth it's weight in gold to me. IMHO

The 4x4 runs directly below the oval cutouts on the floorpan, and just a bit shorter than the distance between the cooling tubes.
Having the lumber forward of the point shown on the diagram allows for more work area and supports the weight just as well. Put the jackstands about 6" from each end of the lumber.
