As always, Thank you in advance for any and all input. I am moving on to tackle the AC in my 94 K1500. Due to a ruptured line from trying to change the high side service valve, I am replacing the AC lines, as well as the accumulator, orifice tube, and condenser. I will be flushing the evaporator as well with the system open. The compressor works fine so I wont be replacing it.
Upon researching replacing the oil in the system, I found a chart on the Mitchell DIY program as shown below. The tag on my compressor is faded and I cannot see the ID information. The chart says Harrison HD6, HR100T, HR110 etc. Does anyone know if the GM OEM compressor from the factory falls into any of these? The only model numbers I found when I checked for new compressors hoping to find an OEM replacement number was LT4.
Also, if this was correct and I placed 3.5 oz in the accumulator, 1 oz in the condenser, and 3 oz in the evaporator, would it be smart to remove the compressor and drain the oil, and refill with new oil to ensure the system accurately had all 8 oz?
Thanks, Mike.
