Air Con Notes
Previous systems up to Oct '00MY used R12 or Freon as a refrigerant.
Later systems used R134a.
Previous systems' lubricant oil is NOT compatible with R134a systems that use PAG oil.
Hoses need to be changed for "Barrier style". "O" rings too as R134a is more leakable than R12
R134a is nore inefficient a coolant so an uprated condenser of the "manifold" or "parallel flow" type is needed
A better alternative to R134a is R406 that doesn't need the lubricant to be evacuated. But does still need the hoses and "O" rings changed out
Kits: two known brand names are Diavia or Eberspacher
If installing a second-hand system, get a new "dryer".
