Now you can install the condensor and the evaporator coils back into the truck. You can also install the compressor (rebuilt $199.95) . Before connecting the lines you'll have to add the new ester oil ($12.00 for 32oz) into the system. My system calls for 10oz of oil. It needs to be spread around a little. I put 5oz in the suction side of the compressor, 1oz in the condensor, 1 oz in the new accumulator, and 3oz in the evaporator. Now you can connect all the hoses and fittings using new o-rings soaked in the ester oil. You can also put on the R134a conversion ports ($12.50) to the high side port above the compressor and the low side port on the accumulator. Check the instructions with the ports that you get because sometimes you remove the old valve cores and sometimes they stay.
