You shouldn't have to fill it unless it has a leak... that's why it's called a sealed system. I would honestly suggest that you are better off having it checked by a qualified tech than attempting to "top it off" yourself. Too much refrigerant in the system can give you problems and impede the performance of the air conditioning.
hahahahahahahahaha !
We took our 05 in to the dealer at 15K miles because the AC wasn't blowing cold air and when they tested it, they said the AC cold air temp was normal.
I went out to the garage and felt it for myself and it was a little over warm at best and I told him this is not acceptable for AC.
He said he can install a can of refigerant for $60 or I can put some in myself but he can't/wouldn't show me were the low pressure valve was located.
I bought a Ford service DVD and they point to it but do not show you a diagram/location/placement of where the low valve is located.
Summer had passed and after several months passing by, I found it in front of the passenger side wheel behind the splash gaurd.
They put the low pressure valve right on top of the accummulator.
I turned on the car, turn on AC to MAX high, connected refrigerant with gauge, gauge showed low, I inserted/pumped refrigerant until the gauge said it was normal and wala, I have cold air.
Also, there's nothing in the manual/warranty that says you void the warranty for adding refrigerant. That's like saying if you change your own oil that you void the engine warranty.
