does anyone know the PAG oil capacity for a 2002 xj8?

related question., I did not open the system and it had zero pressure. It held negative 30 bars for 45 minutes just fine.

do i need to add lubricant before filling with 134a?

I do not know the capacity for each individual component or total system capacity. You cannot tell how much or how little oil is in your system unless you drain the oil from the compressor and flush out every single component (excluding the drier, you replace). The only time you need to add oil is if a component is replaced, Since you said you pulled a vacuum and it held, I would only add freon only. I would highly advise against those stop leak along with freon in a can or those oil with freon in a can. In my experience 9 times out of 10 the leak is on the high pressure side of the system anyways and the pressure is too high for a stop leak liquid. If you really must add oil, I would only add an ounce and no more than that.

 

Se the attached extract from the Jag Workshop Manual.

 

Thanks Addicted and M.

I did what you suggested, no PAG, just 134a, and so far so good. The system blows very cold air, the coldest I have ever felt from automotive a.c..

Im chilling the most.

Next, CD player, and repair the dent on my trunk lid created by me dropping a giant wooden beam on it.

Thanks again, Jeff xj8.
