I unfortunatly blew the motor on my 1999 Chevy Z24 2.4l, recently I have found a new engine for it and I am totally lost on how to install the new one into the old body. Does anyone know of a website or a book that tells me step by step on how to do it. Obviously I would go to the Chiltons manual but I am looking for something that only specializes in motor remomval and installation... it would be a big help if you could leave the website to wwhere I could get the info online or a manual website to where I could buy it

If you've never done mechanical work before, no book is going to help you. There are several ways to do a motor swap and ways of dropping engines. Some people drop the whole subframe, others just pull the motor and leave the trans in the cradle.

If your using the same motor, is all plug n play. Just unhook everthing, yank it out and plug it all back in.

But I am talking with 7 year experience with working on J-bodies alone.

Ok, then it might be worth my time...

0) Disconnect battery.
1) Lay a tarp on the ground to catch liquids.
2) Chock rear wheels.
3) Loosen front wheel lugs
4) E-brake on & Jack car in air and secure with jack stands.
5) Remove wheels
6) Disconnect fuel lines at rail, you will loose a bit of fuel, so catch it in something.
7) Disconnect power steering pump from drive apparatus in your case, from the cam tower, and lay it over the fender on a rag or towel so you don't scratch your paint or tuck it out of the way. It doesn't need to be disconnected at all.
8) Disconnect exhaust manifold from down pipe and unhook rear O2 sensor from engine wire harness.
9) Disconnect all other electrical connections from motor. I would personally take the time to quickly label everything as it saves time re-connecting everything. No guessing, you just know what the pig tail connects to.
10) Disconnect coolant hoses from radiator and catch the coolant in something. Also do you heater core coolant lines at back of motor. A lot will spill.
11) Remove your A/c compressor from the motor and secure it out of the way so you don't have to disconnect the lines and loose your R-134a.

Next steps is your personal call. You can leave the transmission in the car or pull it out with the engine. Its the same amount of work either way.

If you leave it in, you need like a 3 foot 3/8th extension to get one of the tranny bolts out, which is the hardest chose of leaving the tranny in the car and support the tranny near the bell housing when you pull the motor.

If you pull the tranny with the motor, you need to pop the drive shafts out, and then unbolt all the motor mounts. Pull it out the top with a friend helping. Motor will have to be in a 45 degree angle to make it out.

Thats about it really.

Last one I dropped myself, and it was a pain in the ass. But I am stubborn and no one could conform to my schedule to help me.

I found that pulling the crank pulley and mount is much easier with the transmission in the car.Remove the intake manifold makes it much easier.You only have to take off the right wheel off.Another thing and do not do this: DON'T TURN THE CRANKSHAFT BACKWARDS!You will bend the valves this way and turn the crankshaft as you are tightening a bolt.
