Hello,

I am new to the group, and was looking for a detailed write-up for replacing the engine in a 1992 s-10/s015 blazer/jimmy. I have a 1992 4 door, 4 wheel drive Jimmy that needs a new engine, and I will be using another 4.3 L to avoid having to do any changes to the computer, etc. I am hoping to remove the engine alone, and leave the transmission in place. Is there a write-up that details this process available on this forum, or has someone else done this that can lend some guidance? I am very adept at engine replacement/rebuilding, and have done so on numerous types of vehicles, but have been told that this vehicle is a nightmare to replace an engine in, and I am looking for helpful hints (I've been told that the body must be lifted off the frame, etc). Thanks for your help.

really not that hard to do, and i dont know of any indepth writeups, Haynes is pretty good aboutdealing with the engine removal. the oonly real problems are the tranny, which is a pain to disconnect from the engine, with top bolts almost being impossible to get to, and the oil pan and the clearance with front axle. I have done this on my 92 s-10 blazer already,

Best way, jack up truck, support front frame with stands, disconnect the axle,providing clearance with oilpan, and uknbolt the entire engine and tranny and remove the whole thing at wonce,(also, remove front clip entirely for clearance) then its just a matter of yankin it out, bolt up tranny to new engine and slide back in. took me and my buyy about 6 hours for the removal and replacement.

Tip, get a few of those plastic containers,(flat with seperators and a lid) (sold at craft stores or with tackle boxes, for the bolts and label each compartment as you take them off, and label all wires and where they go.

 

Thanks HillBilly! Question: Does the transfer case then remain in the truck? If so, your way does sound far easier. My main thing is I did not want to get into removing the transfer case and all, as that is not a fun job! I was already planning on removing the front clip, so will take your advice and just rip the entire thing out, then re-assemble on the floor, and re-insert into the truck. My uncle really does not want to remove the trans for some reason (he always left them in when rebuilding his race engines). I customarily take them both at once. I am certain it will work well. Thanks.
