The actor remains a friend of his ex-colleague and it is thought that his wife Clare, who works for a private health company, is the person who found Jones his place in rehab.
Kennedy, who played Weatherfield favourite Curly Watts, once battled a drink problem himself but has been sober for 12 years.
Speaking to The Mirror about Jones, he explained: "Someone has got to be there for people when they decide enough is enough."
Jones, best known for his ten-year stint as Les Battersby on the soap, last week confessed that a drunken rage had caused him to grab the wheel of his wife's car while she was driving and threaten to kill them both.
Kennedy continued: "Hopefully he is off to rehab pretty much straight away. Bruce's problem is pretty acute.
"I said, 'I don't want to be stood over a hole in the ground looking at your coffin, because that is the next step for you. If you don't kill yourself, you will end up killing someone else'.
"I said to him, 'I will point you the way, but the hard work has to come from you'. I think he has been sufficiently frightened by the depths to which he has sunk, to finally do something."
