HI All well I checked it again yesterday, one of the posts said to immerses the can in hot water so the can had a bit of fluid left in it so, a container of boiling water, then reconnected it and toped off the system, my AC is now cold in fact very cold so Im well pleased with the result and as AC system do lose they say up to 10% a year I still have 2 sealed cans to play with
after removing the cone I removed the hose , and only a very small amount of gas came out so the boiling water trick recommended worked well, so thanks who ever said it
and my D2 is a1999, and I have never done the AC before
