[W126 Coupe] air conditioner Refrigerant question

[Mike R.]

I have R12 in the 560SEC and R134 in the 560SEL. Both exhibit this problem -
not much cooling when stopped but 5 mph and it blows cold.

 

Later,

HOT town (pun intended)

That's what's in my system. Works well, but when the temperature starts to
get into the mid 90's and higher, I do find my cooling at idle to not be
optimal (but still, it's cool, just not cold). Just moving a tiny bit
alleviates this.

Duracool, works great, 3 years now with no problem. Charged and topped up 8
cars last year and about 7 so far this year.

Larger molecules, lower head pressures, reasonably priced, no licences
required, Use less. Direct top up for r134, r12 systems should be evacuated,
before charged with Duracool. I get great technical support, and get to talk
to real live technicians.

EDUCATE yourself before using, you DO NOT use the same amount as R134, etc.
You CAN'T rely on the sight glass, If you fill until all the bubbles are
gone, you are overfilled. Need any other help, let me know. Iain
