@house, whenever I top up my fla batts with distilled water, and I look inside, the whole electrolyte appears very cloudy or dirty, and then clears up after a while. it appears I have lots of sediments at the bottom, is this a cause for alarm, should I drain the electrolyte and refill with fresh one?

mosbus:
yes pls do it.

lol, was wishing you would not say this, I would be sad, if the super cooling fails because of this.
you feel the air inside would cause the system to develop a leak in the future, and is even preventing my ac from chilling even better?

is any refrigerant beta?, ie the big 5kg green bottle of gas vs the small 1kg bottles, is any better than the other, I intend to refill with Cheb
refrigerant, as its said to be better than maxxron

so I have my evaporator recently replced, and ac shaft seal repaired.the technician doesn't have a vacuum pump, thus didn't vacuum it. this is about 4wks after the job, car chills ok, have seen another technician who has a vacuum pump, would you advice me to go and have it vacuumed and refilled properly
