Default Difficulty for switching out turbocharger?

It appears my turbochargers needs to be replaced.. Leaking oil, squealing, etc. Just wondering how difficult removing and re-installing (a new one) the turbo can be?

Thanks for the help.

I haven't replaced on on this particular car, but from the looks of it I'm gonna guess less than 2 hours.

Haven't replaced one on my 9-3 yet but I have on my '90 Volvo. Getting to the manifold bolts are likely the only hard part and also dealing with possible metal fatigue. Use plenty of pb blaster and slow patience to prevent breaking studs/bolts and it should be as simple as removing some hoses, unbolting a few bolts and repeat in reverse. Rebuilding though is a world I know nothing of

It will be at least a morning, not counting time spent applying PB Blaster to nuts on the manifold and on the downpipe flange.

I've removed the turbo and manifold as a complete unit before, but this might cause other issues.

Apply the PB Blaster (or any penetrating solvent) the day before you try this while the engine is warm -- NOT HOT! -- tap the nuts with a hammer and repeat a few hours before trying to remove them. Even after this, odds are high that the downpipe bolts are rusted tight and will shear when you try to loosen them. No prob: You should probably go to the dealer and get two replacement downpipe bolts in advance, just in case.

CRC's Freeze Off is a far superior product working in minutes.

On completion put oil in the turbo. B4 start, pull the fuel pump fuse and turn the engine over. I did this 6 or 7 times with the plugs out (faster spin) to be sure oil was pumped through the system.

I lost a turbo once on first start by only turning the engine over a few times so lean on the caution side.
