How much Freon and oil to put in a new used compressor

These dont use Freon. Freon is R22

These use R134 -46oz and 13oz of oil. You need to pump down the system though once the oil is added and let it sit with the vacuum pump to remove any moisture. Any moisture left in the system will ruin your expansion valve and compressor quickly. Then add one can of R134 and run the system for a minute to distribute the oil. then add more R134 until the gauges show it at the right pressure for your ambient air .

Oil and refrigerant capacity for 88 chevy s10 pickup

There should have been a sticker on or around the accumulator with the specs.
Oil capacity is the amount drained from the old compressor, plus 3 oz. for the accumulator. Freon charge would be around 36oz or 3 cans.
You would put in 2 cans and then add until the pressure readings are within spec.

How do you convert r12 to r134 on a Ford Truck?

If there are any leaks in the system, they should be addressed first. The system needs to be recovered of any r-12 and remove the oil and the compressor oil. The accumulator (or receiver/dryer) needs to be replaced. The system needs to have the proper amount of r134 compatable oil added back in. You can measaure what comes out of the compressor and add that amount back in. Then add about one oz. per major component (condenser, evaporator, dryer). Ester oil is good for retro fitting because it is compatable with both oils. There are fittings you can buy (kit?) that screw onto your r-12 ports that allow you to evacuate and recharge it with r134-a. Typically, the new charge amount will be approximately 80 percent of the old charge. IE: if the vehicle held 3.75# of r-12 (x.8) is 3# of r134-a.
