Hello
I have a thread in General Tech on my dilemma but these
questions might be better here. I have not performed these procedures
before so the consequences aren't obvious to me. I was hoping that one of
you turbo wranglers could spare a moment
With respect to turbocharger removal/replacement…

1. The manual suggests coolant draining as preliminary step
Is this necessary for removing the turbo for inspection/replacement
Any gotchas if you don't

2. The manual suggests removing the catalytic converter as a preliminary step
Is this helpful/ convenient worth the trouble ?

3. The manual suggests unbolting the motor mount and tilting the engine
Worth the trouble / any gotchas ?

For a more detailed look at possible problems
Is it worth the trouble to pull the hood and maybe the fascia ?

For the first two - coolant goes to the turbo, so yes you have to drain. And the cat bolts to the turbo, so you have to get that end off anyway - I'm guessing removing the whole thing gives you more room to work. (For #3, I can't tell you.)

Short and simple, yes to all of the above with the exception of the front fascia. It is able to be done with the hood on as well.

The reason they want you to loosen the engine mount and jack the engine is to allow better clearance for disconnecting the turbo from the Cat. DO NOT completely remove the bolt from the mount, it is a bitch to get back in. Loosen it a bunch (3/4 inch) and then jack the engine using the side of the oil pan.

So…
All is true so far. The turbo could be removed without completely removing the oil and coolant lines and therefore skipping the coolant drain procedure. Having said that it would be more difficult removing the last nut connecting the turbo to the exhaust manifold.

I am sure this is nuts to try without removing the catalytic converter.

The engine tilt is bugging me Just looking at it right now it seems tilted after I dropped
it back down. But it may be that I just need a break

The oil return line port on the block needs a cork or a rag once you pull the turbo

Some of the 15mm nuts and bolts require considerable grunt to move.

The LNF motor is tilted. That's normal.
