I have a system that did work several years ago but lost refrigerant and I want to tune it up a bit. I am replacing my compressor (york) with a new Sanden SD-508. I plan to stick with R-12 and will be replacing all of the old hose's. I have removed and flushed the condenser and evaporator with lacquer thinner and have a new expansion valve and drier. I plan to use the service valves that were originally on the york compressor, they will attach to the sanden perfectly. The compressor I am going to use has never been mounted, and has oil in it, mineral I think. I have the following questions:
1. What is the refrigerant capacity of my jeep R-12 system?
2. What is the oil capacity of my system (SD-508), and how should it be split?
3. Should I drain the compressor and refill with Ester oil or is this bad for the Sanden?
4. Should I put some oil (from the system total) into the evap, drier and condenser or just let it circulate from the compressor?
5. Any problem using the original york style service valves?
1. Check the Napa listing.
2. 7 ounces for standard Sanden. Check supplier if it's a knock off.
3. Depends on the ester used in my opinion. If your running R12 use mineral oil unless it came with a PAG. Then use BVA Auto Glo.
4. You need to have the proper amount for the system.
5. Depends on the fittings on your replacement compressor. I would have asked the suppler about this before ordering.
1. Thank you for the link, that is great info!
2. 7oz it is.
3. I have just ordered BVA auto glo from this site and will use it in place of whats in the comp now.
4. I understand I need the proper amount for the system. Do I need to split it up among the components or put the entire amount in the flushed out system. None of the hoses, evap or condenser currently have any oil in them. I have heard/read it could be done either way?
5. Already have them installed, just wondering if anyone thinks its a bad idea to use them instead the type with a shrader valve.
Thanks for the reply back, I appreciate it.
80% Compressor 20% drier should be fine. Everyone has their own method.
