I have not been able to find the system capacity of the original '67 A/C system using R-12.
Does anyone have a service manual with this information?
Thanks,
Mike

3 lbs and 4 oz of R12 refrigerant.

Do you have the correct amount and type of oil??

Probably, the shop is going to do it.
What is the correct type and amount of oil for an R-12 system?
Thanks,
Mike

Powershift

R12 Refrigeration Oil, a wax-free mineral oil with a viscosity of 500 SUS at 100 F. NAPA #TEM209500 or equivalent.

Total system capacity is 11 oz.

6 oz in compressor (A6 type)
3 oz in evaporator
1 oz in condenser
1 oz in receiver drier.

Ester oil can also be used for R12 refrigerant , but it is not as good as the mineral oil. Use viscosity 100 or 150 CSt.
