A/C Compressor help (Page 1/1)

I am in the process of replacing my compressor on my '87 GT and retrofitting my system to R134a. I have searched for the answer to two specific questions and was not able to find them. I have already done all of the system flushing, replace the accumulator and orifice tube and clean the condenser. Shortly, I am about to start with installing the compressor. I bought a 4 Seasons compressor which states that it has 3 oz of oil in the compressor but does not state what type of oil. I certainly do not want to mix two different types of oil. I searched online and at 4 Seasons website to see if I could identify the type of oil with no success. To those who have installed this type of compressor (HR6):

1. Do you know what type of oil it came with?

2. For the high and low pressure switch with the two pigtails, is there a write up on how to wire them up to vehicle the wiring harness?

Thanks,
Alex

1. Call Four Seasons with the part number of the compressor and ask them to be sure

Customer Service toll-free: 888-505-4567

2. Existing wire to new pigtail wire (either wire), and the leftover new pigtail wire to a ground. Most people use a ground eyelet, and one of the compressor mounting bolts as the ground. The original compressor switches grounded through the compressor body.

I poured out the oil and replaced it with Ester

I recently did the exact same thing on my 87GT. I added PAG 150. Worked great. I also replaced the pressure switches.
