Compressor seized on 96 passat tdi. Causing belt to burn through.
car is still drivable short distances (no ac of course and no alternator).
I have ordered a rebuilt compressor, drier and...
What is my best strategy?
My plan is to drive to ac service shop and have them evacuate ac system.
Remove and replace components leaving stuff disconnected.
At this stage I assume I have to flush the old components.
Can I flush and clean system myself?
Or do I go to service station and have them flush everything.
Check out the procedures Karl has listed for flushing in the flushing forum on this site. With the correct equipment and some effort you should be able to get your system clean of debris and old oil.
Thanks for the support and let us know if you have some follow up questions.
Is the compressor completely seized, or just the pulley bearing? If you can still turn the inner shaft that drives the compressor itself, the internals should be OK, and debris would not be an issue. Heat from the bearing may have melted the shaft seal and caused a leak though, best solved by replacing the whole compressor.

New compressor says SDV7AB on it. The same??
Mitchell has 4.5 ounces listed for this system.
Different that it's not going to work for you?
I got the rest of my AC toy box today.
The drier looks to be a good match so I took the
band saw to the old one. Nothing too bad in there just some black
dis-coloring that wipes off. Is this a bad sign?
That pretty much describes it. gray residue that
I flushed the condenser today and replaced the evap
valve. The evap valve came with 5 orings. Damn if I
could find where that fifth one went. Did I miss something???
Glad that wife has another car to drive while
I play car scientist.
