Help ID 2 engine parts: 1999 GMC Suburban

[w140amg]

Need help identifying two hoses.

1) Passenger side hose, behind the alternator.

2) Driver’s side, looks like other end it’s going to the intake manifold.

I need to order the two parts to replace bc they will not come off, so i will have to break them off. And get new replacements.

Thank you in advance.

Heater inlet hose and EGR line.

The one on the passenger side is GM’s awful quick connect for the heater hose. I’d replace it with a 5/8 nipple with 1/2 NPT thread. That’s what I’m doing with mine.

Snap it off and get a Lisle 62200 to get the nub out.

Why snap it off? How abought try unscrewing it first, THEN, if it snaps off use a easy out to remove it.
