Trailblazer Envoy 4.2 Engine swap , Part 1

[@blueeyedscorpio7]

I'm debating if I should get a new engine.. if that's what's wrong with mine or just getting rid of it😕

[@snoopdog6793]

Hopefully the customer had enough money to get a alignment and replace them horrible bald tires.

[@MrPetervp14]

What did you do with the AC system.? Did you recover or did you leave it a sealed system and work around it.?

[@jaysgarage3616]

Sorry for the late reply , the system was evacuated and refilled after. I can usually find a way not to drain the systems but this one I was not able.

خواجه وما يعرف يشتغل فاكي الصدام والكشافات والله إني افك المكينة من غير فك صدام ولا كشافات افك واركب في نفس اليوم لو القطع جاهزة

[@waynethomas1726]

Assuming you still have the vehicle, the washer solvent hoses separate further up. You don't have to remove the hose at the pumps and cap them to keep them from dripping. Look further up and see how they separate.

[@jaysgarage3616]

I seen that after but thanks all the same.

[@rogerlawson1818]

Very good instructions and tips. Thank you. How many hours would estimate for the R&R?

[@jaysgarage3616]

First time , 30 hours for a weekend novice.

[@jeffe7532]

Hey. Love the tips. I had to scroll through a lot of Jay Leno's videos (who I really like) to find you. :-)

[@jaysgarage3616]

Ha , I like the Jay Leno stuff as well. Sometimes I find my channel easy and sometimes it's all Jay Leno but thanks for scrolling through and leaving a reply.

What tools should I have whenever I tackle my engine swap I just want to have everything so it saves me as much time as possible

[@jaysgarage3616]

Basic had tools , two long extensions for both starter and transmission (top) bolts. Fuel line disconnect tool , clutch fan tool (should be able to rent) and a 35mm deep socket for the front axle nuts. You will need a hammer , pliers , screw diver and a pry bar , I had to use map gas to heat up the exhaust bolts before I could get them out. Hope this helps!

Last week I ran across a 2008 with an LH6 5.3l in it at the local pick and pull. I’m just not in the need for a GenIV aluminum block engine right now, wish I was. It’s in the car section and it’s pretty much untouched other than someone got the front seats.

[@joeyh2083]

Please keep going with these videos. This is definitely the best video I've found on Trailblazers. Your very good at showing and explaining things

[@jaysgarage3616]

Thanks for the comment Joey , I will be continuing with the Trailblazer video and the second one should be up soon. Thanks.

[@roguetrail9495]

Ditto.. Very well done..

[@Isaac-lo7yc]

about how many hours labor will take you from start to finish on this engine removal and install

[@jaysgarage3616]

I'm actually not done. No hoist , some issues with bolts , top end disassembly , drop crossmember to get top trans bolts , front suspension disassembly , pull , r&r parts , reinstall , charge A/C change seal in front diff etc. 16 hours is my guess. It will take some people longer , I might be 20 but I only work on it in small amounts.

[@terrancesmith1276]

20 hours start to fired up motor ? And cost on this with out the junk yard motor

[@jhargrove1108]

I need the front engine hook for pulling one. Did you have an extra?

[@jaysgarage3616]

Sorry John , I do not.

[@sugarwalker89]

great job young man!

[@jaysgarage3616]

Thanks for the comment.

[@bensonkilpatrick9981]

How do you find out if a 09 Trailblazer I6 will fit in a 06

[@jaysgarage3616]

Should be fine but you can verify by checking the vin from both engines. 8th digit will be an S

[@kravmaga7070]

next swap i do will be in a bigger vehicle than a gbody. Maybe an old truck , van bronco, el camino... cuz that G body was a tight fit, especially around heater box. i couldve made it fit better by removing the intake, and entire front end but you dont know about these problems unti they happen and turn out to be more work then the removal i mentioned. but overal it was pretty good candidate cuz it was 99% rust free, almost everything worked with exception of washer pump motor... then the hood latch broke in first 2 weeks. Do you happen to have any tuning expertise with tunerpro?

[@jaysgarage3616]

Swaps are always a learning curve , the first one is always the hardest. If I were to do the Sonoma again I would do it different. I do not have any experience with "Tunerpro" nor have I done much tuning so I was going to spend many evenings learning , I was going to use HP Tuners.

[@kravmaga7070]

@@jaysgarage3616 yeah Hptuners is probly better is you plan on doin more than 1 pcm. Tunerpro was easy enough once i found the XDF but when you run into random error problems then it gets anxious wondering what to do in fear of bricking only pcm.

[@kingnasty5381]

Brother I beg of u. Help me.. I have a 2005/6 trailblazer 4.2ls and swapped to 2007 engine . Do I have to change out the ecu? Bcm?? The engine is different 292 hp vs the 275 I had but wire harness fits everything. Codes p2769 p1815 and the shift light isnt illuminating when in gear nor is the speedometer now working and it's fairly new swap. Any help is appreciated. You def know what ur doing . HELP

[@jaysgarage3616]

Ok , don't really remember to much but.... The temp sensor wire need lengthening? The coils are different , you need the PCM and maf from the donor vehicle and possibly a few smaller things. 1815 Check the trans harness , big sensor on the side 2769 Torque Converter clutch circuit , again check for harness damage and go through what was done , pinched wires etc.
