There are actually 3 parts. Black is outboard and white is inboard with the 3rd straight black connector plugged onto that. I would do them all because they are all equally prone to failure:

thank you. that will. make it much easier. I'm guessing you just squeeze the tabs and pull? no tool needed to remove?

it's got 140k on it and a 2011. so yeah it's due for a coolent flush anyways. good time to do it.


thanks again.

Squeeze the tabs and push in on the hose before you pull. I used a pair of pliers to help me squeeze the tabs.

Wear gloves when working in that area, as the firewall insulation is quite aggressive, and your hands will itch like H-e-l-l for the next few days.

I just did this on my truck. I ended up using a small saw from my friend to cut off those crappy connectors. Ill go with the gruven maybe next month when i address every hose in the cooling system. But what about the rear? I didnread that the rear heater core has some problem with the line breaking or something.
