Car: 2015 Malibu LTZ 2.0l Turbo.

Does anyone have any tips on removing those extra lines for the coolant and oil? Do I even have to remove them all the way?

In the pic below, coolant is red and oil is green. I think I can just disconnect the coolant one and get it out of the way but I do not know what the fitting is at the engine for the oil line. Do I need a special took to disconnect?

A closer shot of the fitting.

Lastly, I think the oil connection at the turbo is also some kind of quick disconnect?

Thanks in advance

In case anyone comes looking for answers, these are all part of the PVC system. The connectors can be tricky to remove so you may want to consider all new parts. Here are the part numbers and prices as of March 2025

12673868 <-- pvc valve hose $158.52
12663027 <-- pvc valve $28.74
25201122 <-- second hose $36.75

Here is a youtube video that shows the whole process: Youtube video link

If you need more info, look for the "2.0 pvc valve Cadillac Malibu" on YouTube. There's a lot more content for the Cadillac 2.0t then the Malibu 2.0t.
