Is it possible to install an engine from a 2005 trailblazer into a 2007 trailblazer

change the brain box with it..

I'm assuming that would be the only difference? Some mechanics have told me that they wouldn't work but could not tell me why? So replacing the computer would make the interchange possible?

i have the same problem im intall a 2003 eng to a 2006 is fit perfet but dont want to star what can i do

True. That is what I am going through. 4.2 engine for 2006&7 work together only across other models. Envoy, trailblazer and Sabb 97x or what ever it is.

I had a mechanic pull my 2006 trailblazer 4.2 engine to place in my 2005 Envoy and he said it would not work (after he pulled it). He changed me only $200 for pulling the engine out. I still have it if anyone needs one. It has 8,800 on the newer engine and 127,000 on the trans. They are still married together. I am looking into a cheap body but having difficulty finding one. So if you want it email me at jrfortman(at)livedotcom.

Hey Gurus49JH I have a 2001 trailblazer body for sale if your interested in it

I just put a 2004 4.2l motor in my 2007 envoy. Perfect match. Just keep the newer computer because the plugs won't fit and extend your temp sensor wires v because they're in the back of the motor and the 06 is in the front. Everything worked great started up and runs great!

Hows that possible when i have a 03 traiblazer 4.2 2wd and i bought and 06 due to the heads being better and im having to buy the ecm...06 harnesses and the fuel dilvery is different

Because he swapped the intake, injectors and all

Does anyone know if I can put a 2005 GMC on boy 4.2 l engine in A04 GMC envoy 4 by 4

I have a question

What years will interchange with the 2002 Chevy Trailblazer? I have the option to buy two different years for parts and I need to know which would work best for part replacement, any suggestions?

Do I have to change out engine harness also 2004 envoy I have a 2008 in it now

Have a 2008 trailblazer trying to put a 2004 motor in a 2008 will it work

Hey GuruBSRBS I currently have a 2002 Trailblazer 4.2 IL6 entire vehicle for sale. Motor threw some kind of bearing but still runs just wont make it far. It has a brand new radiator, water pump, plugs, ignition coils, and i honestly cant remember everything else we've replaced on It. Just got an offer on a 4.2L envoy motor to drop in it for $450, but I just want it gone. Nothing but problems from the start. I'm the 3rd owner with clean title in hand. If I can't sell it it'll be going for scrap. Guess my question is will the envoy 4.2L fit in my 2002 Trailblazer? I haven't been told yet what year the envoy motor is tho

DO YOU STILL HAVE I'M LOOKING FOR A FRAME FOR MY 2006 WITH 49000 MILES ON IT BUT IT'S BEEN SETTING FOR ABOUT 2 YEARS AND FRAME IS ATE OUT AND DO YOU KNOW IF MY BODY WILL FIT MOTOR AND ALL

in not a few words. 2002 to 2004 are interchangeable for those years only 2005 is a lone wolf 2005 only 2006 to 2007 are interchangeable for those years only 2008 to 2008 are interchangeable for those yeas only the differences are in the crankshaft timing built into the crankshaft they have different number of teeth for the sensor to pick up on.
