replacing lown 12a with new 12a

i dont post on here uch, but i check through here alot just to read up

i recently blew my engine back over the summer, i found another engine from a guy on here with 84k on it, tested the engine couldnt find any problems with it.

to the point-

i have never done an engine swap and this car is really the first car i have had that ive done my own work on.

i plan on sticking the engine i recently purchased in for the time being, and rebuild the blown engine in my free time.


im not too sure where to start with this project since its all new to me. i guess im just searching for a few starter tips on taking the ld one out and replacing it.



thanks, anything helps

Buy a haynes manual.... Keep it close, try reading it all the way through once and get a basic Idea of how the process goes... Then take the book outside and look at the engine bay locating the bolts as you RE-READ the "engine removal" section. MArk any areas you feel may cause you trouble..(with a highlighter)

Take PB lube, or wd-40, or a penetrating lube and shoot ALL the bolts you plan on removing like the DAY BEFORE you start. (to ease the pain, trust me)

Buy a BOX of ziplock bags and a sharpee, LABEL EACH BAG as you remove the parts and place them into the appropreate bag. (this keeps it organized)

Go one step at a time and TAKE YOUR TIME... Double check everything, then check it again..

Remove all gaskets from the waterpump area, carburator area, intake area, anywhere that becomes exposed and COMPLETELY remove the gasket, and replace with new... (or you'll be sorry)

do regular tune-up on the car while it's apart, also consider a carb rebuild too.... (why not?)

Belts, Plugs, Wires, Coils, OIL, filters (air and liquid), paint anything you want painted PRIOR to re-install... Also Bleach and wetsand your engine bay nothing looks worse then a nice new engine in a dirty nasty bay.....

Anyways, it's a piece of cake, just keep organized..

Good luck

and take lots of pictures before removing anything...and Finally, once the engine is out, have someone take your pics while you're in the engine compartment.

What year is your car and what year car is the enigne from?

You may have to mod the exeheast if the two are not from the same year or series.

There is a bolt in the top of the engine that has a lift ring, the bolt goes throught the bell housing and has a nut on the back side. Remove the nut, not the bolt. The bellhousing is not threaded so you leave the bolt in to hold the lift ring.


Get the car in the air. I jack it up and then use car ramps under all four wheels.

Pull the engine with the tranny. It is much easier.

General procedure.

Remove drive shaft.
disconnect wiring to starter and trans, including the spedo cable.
disconnect the exheast at the header.
put a jack under the trans.
Remove the trans mount.

Remove the hood.
pull the water lines.
remove the rad.
disconnect the electric connections and fuel lines.
disconnect the throtal cables.
If you have the AC, you can remove the pump and hang it to the side, living the hoses connected to it.
Get in the car and remove the gear stick.
Remove the nuts that hold the engine mounts to the brace.
Remove the oil cooler lines if you have them.
Take off the coil wires.

Should be ready to pull. Give it a once over and pull it.

Every wire and hose you disconnect, put a piece of tape on each side of the connector and number so that you can hook everything back up again correctly.

One by one, consider replacing every piece of rubber vacuum hose as you reconnect, will minimize the mysterious vacuum leaks.

Good Luck
