r-34a
Factory R-12 Should be conveted to R-134
Dexron III should be a safe bet.
the kind that it takes
A 1998 Buick would use R134a refrigerant.
R 134A (hint it is also in your manual)
If it's later than 99 should be 134A
my 2000 buck century smells of gas from outside and air condition vent
the kind that convert co2 and oxides of nitrogen into other stuff...
Chains are made of metal. What engine?
It takes 5w30. Use synthetic blend.
10w30 says it right on the oil cap.
R134 _ Well Mine did
