Here's a well-done, blow-by-blow description of how to change the expansion valve on a W126 chassis.

That's a great writeup.

More work that I would have thought.

Thanks for the link.

Good deal. Now what do I need to do so I can flush the evap core...

In the end, it was all for naught (I had to replace the evap anyway) but I pulled the old TXV, drilled it out so that fluid could flow through it, reinstalled the drilled TXV in the car and blew the flush though the evap from the engine compartment using the liquid and suction lines from the cabin.

TXV? Is there a DIY on how to do this?
