I have a coolant link coming from a plastic "Y" fitting.
It is located directly underneath the front of the intake on the drivers side.

Any idea what it is called? attempted searches turned up nothing for me.

Any idea how difficult it is for a backyard mechanic to replace this or should I just take it to an independent shop and if so, any idea how much I should expect to pay? is this a $500 repair?

See the picture, thanks!
