Hi, I have done this and it is not too bad, but will take you about 4 hours if you are good, and longer if you have not done much mechanics.
The trick is to find a reasonably priced turbo, check ebay. There is a dude on there that just does rebuilt turbos. Very good, got mine for $
I have been reading up on turbo replacement procedure and I have found this list: First, there are a couple of questions that I have about the list:
2 air openings, pretty easy to figure out
2 exhaust openings, pretty easy to figure out
3 round openings in the center, all banjo bolts?
1 round / two bolt opening in the center.
1 Hose fitting off of the waste-gate
1 Hose fitting off of the air side of the turbo.
STEP 1 Open the expansion tank cap to release the system pressure.
STEP 2 Raise the car & Remove the lower front cover under the car
STEP 3 Drain off the coolant & Remove the turbo brackets
STEP 4 Loosen the return fitting and the pipe from the turbo to the block
STEP 5 Loosen the oil pipe between the filter adapter and the turbo
STEP 6 Lower the car to the floor & Remove the bypass valve & Unplug the connector from the control valve
STEP 7 Disconnect the mass air flow sensor connector & Loosen the hoses to the turbo
STEP 8 Remove the crankcase banjo bolt from the intake manifold and unscrew the bolt from the cam cover
STEP 9 Move the pipe and wiring aside & Remove the engine lifting eye
STEP 10 Remove the mass air flow sensor and air hose
STEP 11 Remove the exhaust manifold heat shield by removing the nut and two clips from underneath
STEP 12 Undo the intake manifold clamp at the turbo & remove the intake
STEP 13 Disconnect the hose clip on the hose between the intercooler & turbo & plug it to keep something from falling in it
STEP 14 Loosen the front exhaust system from the turbo & lower the front exhaust system away from the turbo (DO NOT BEND -THE FLEX HOSE)
STEP 15 Remove the oil pipe from the oil filter adapter & grab the copper washers
STEP 16 Loosen the coolant pipe by the turbo & grab the copper washers & loosen the coolant pipe bolt
STEP 17 Remove the coolant return pipe from the cylinder head & pressure sensor bracket. Once again, Grab the copper washers
STEP 18 Undo the coolant return pipe bolt by the turbo
STEP 19 Undo the nuts securing the turbo to the exhaust manifold. (spray the nuts with WD40)
STEP 20 Install in Reverse
Just did this for the first time. Here are a few hints that may help others.
1) PB BLASTER is your friend. Remove the exhaust top front heat shield and hit exhaust nuts with PB Blaster as soon as you start the job, or night before.
2) Make sure that you have 12mm closed end wrench with AND without ratchet. Also a 1/2 size 12mm socket if you can find / make. These will help.
3) You don't have to remove the oil filter, but there one bolt that it would be nice for. I did not and did manage to get the job done.
4) Take you time. More of finding the right tool combination for each bolt.
5) Two banjo bolts on the turbo were really on there. Needed to use a mini-acetylene torch to eat up.
6) Have extracting sockets and bits ready just in case there are issues getting bolts / nuts off.
Turbo had quite a bit of end-play, but spun fine. Classic symptoms, blue smoke at start up and from time to time when driving. It was also making a bit of noise at idle.
Also, should get new copper washers. I did not have I have some micro leaks from time to time but nothing bad.

Just replaced my 2005 envoy thermostat, and it might be the same. Here is what I had to do.
1. First, the thermostat was located on the driver side behind the alternator. The hose comes from the bottom of the radiator, not the top like most vehicles I have worked on.
2. You need to remove the belt by taking tension off of it. The tensioner is on the passenger side, under the steering pump. I used a socket wrench, placed in in the square hole on the tensioner, attached a pipe for leverage to the socket, and pulled until the belt was loose.
3. Next is removing the alternator. Best if you first disconnect your battery, as there is a hot line to the alternator. Disconnect the wiring harness located on the top. Remove the bracket bolts that hold the alternator. You might want to place something under the alternator to prevent it from damaging the small wheel under it as it will be heavy and free after you remove the bolts. I also removed the bracket to get full access to the hose and thermostat. There is a red wire that connects to the alternator, remove it and now the alternator can be pulled out and set to the side.
4. Once all this is out of the way, you can remove the hose to the thermostat (I assume you have drained the radiator).
5. Remove the two bolts hold the thermostat to the engine.
6 Replace the thermostat and reverse the order of the steps above.
I read that some can do this without removing the alternator or just loosening, but it is tight and makes the job a lot harder.
Hope this helps...Joe
