Model: Wrangler TJ
Engine Size: 4.0
Refrigerant Type: R134a
Country of Origin: United States
I suspected a leak in the system after purchasing the vehicle due to the compressor cycling on and off every few seconds. I charged the system, added uv dye and found the leak (the manifold on top of the compressor). I had the refrigerant reclaimed from the system by a local shop, and I've replaced the seals on the manifold. Before changing the seals, I put the system under vacuum, and it lost 4" Hg overnight. After replacing the seals it lost 2" Hg overnight. First, not sure if this means the leak is fixed or not. Second, I need to determine how much oil to add to the system when I recharge it. (I plan to replace the accumulator before charging again, but have not done it yet.) Any assistance is appreciated. Thanks.
2 to3 ounces if you change the accumulator. The issue will be how much oil was lost form your leaks. There really is no way to tell other than judging the oil around the leak areas.
I hadn't thought about the leak, I was thinking about possible oil loss through the refrigeration reclaiming process.
Reclaiming generally doesn't remove enough oil to worry about. Leaks don't lose much oil either unless it is at the bottom of a component where there is oil pooled inside.
