Unless it is marked on the can they usually do not have dye in them. They have regular cans, cans with "stop leak" in them cans with dye (they are usually purple) cans with PAG in them. Then you can buy just the oil as well. I did one last week for a guy and told him to buy a can with dye in it and then told him not to leave it in his car. He did and came out now he has dye all over the inside of one of he seats. Then next day he brought in another can and I filled it and ended up needing more I have about 4 cans here and used one. Man that dye sucks to get out.
OP make sure to get the correct amount of oil, I don't remember how much you are supposed to use on an accumulator change out but it's around an ounce or so. Also if your having it professionally done they should know.
