I changed everything to fit for R134a (better say - my Garage changed it
) - But we didīnt know how much ml (or kg) fits. At one time someone gave us a limit of 200 - 300 ml / thats 0,2 - 0,3 kg - but that
was not the goal
. We canīt get cool air.
So i searched my Manual but there is no Info in ml - it help my to hear that 1,75lbs is about the minimum, thats about 800ml. Now there are 750ml filled, and it is cool, but it could be cooler
so i try 900ml - because you schould fill up 10% less than R12 with R134a.
That schould fit.
I donīt know, but i think i havenīt a Warning sign for too low Climatic compression. I disasabled the car and know most every screw, because i
restore my Caddy and i have 2 of them.
If anyone have a Fleetwood Brougham 1988 or 1989 with 5l engine, every
tip and hint is welcome.
But i think after reading your post and calculating lbs into kg - 750ml are the very low minimum,
so i will fill up to 900 and check again.
