Heater Core Hose

How do you take off this quick disconnect plastic piece from the heater core. Its leaking and I bought all the tools but it still won't budge. Plus this piece is a Tee, what do I do?

I had the same problem ,used the tools nothing worked finally got one end off but the pipes are so stiff i gave up on the others,i was up dating to the larger tee's for the rear heater.I don't know the secret but it is very tight to work on.Sorry not much help.

Same with me, I didn't have any luck taking any of the fittings off when I was wanting to flush out everything separately when I last changed my coolant! Didn't wanna break anything so I left it as is!
