Factory R-12
Should be conveted to R-134
r-34a
the kind that it takes
A 1998 Buick would use R134a refrigerant.
R 134A (hint it is also in your manual)
R-12
If it's later than 99 should be 134A
my 2000 buck century smells of gas from outside and air condition vent
Chains are made of metal. What engine?
Dextron III or it's equivalent.
Dexron III should be a safe bet.
manuel says use ONLY fluid labeled DEXRON-III made for this transaxle
first off its not freon.second you have to find out what kind of system you because if you put the wrong refrigerant in you can damage the system. the right way to do it is to take it to a professional the system has to be tested and ran through various machines. plus theres a high pressure side and low pressure side you dont want to get the two mixed up
