Progress update, Coolant Pipe Replacement:
-setting myself up for success with my workspace is a big task, two days
work.

-cleaning the pipes: they are filthy with manufacturing grease and swarf.
But how do you clean them?  A cloth on a rope?  Use the recovered coolant
as the cleaning solution?  Or is there a soap or detergent which is safe to
use?  How do I know the manufacturing gunk is phosphate-free?

-Radiator: it's not broken; but I'm tempted to change it anyways.  Bad
idea?  How do I clean it or test it?  Just leave it?

-Is there a big difference between the BEHR radiator and the other after
market radiators?

-Draining and capturing the coolant.  I have a big tray to catch any
spills.  What's the best draining connection to open?

-Is high-spec Euro phosphate-free coolant worth the extra 20 bucks?

ps -- after an oil and filter change, my oil pressure has bounced back up
to 28 psi at 4000rpm.
