Refrigerant Type: r-134a
Country of Origin: United States

I am getting a lot of late mid size and small gm cars.
That come in with low charge.
Customers have had most of them recharged other places and leak dye added to most most almost all recharged within last 2 mo.

I pump out and recharge and check for leaks with leak dye and light and sniffer and look for oil spots and can not find any leaks.
So far none of them have come back with any cooling problems.

Can the leak be sealing there self up or just taking a while to leak off or maybe improper re charge at other places?

Thanks for any info.
