Did the repair earlier today, think it took about 45 min although I didn't do a full bleed.

Haven't looked at the tank too closely but from what I can tell the bottom o-ring was giving out so good thing I waited for the hose. First time working with those quick disconnect hoses which I guess are easier to work with but if they only last for 10 years and with the extra cost.... Makes me miss the ol hose clamp.

Got coolant everywhere so I'm sure I'll be smelling it for a while, but I'll be monitoring the level best I can to see if there's any loss. If it is the o-ring like I think I'll definitely be replacing all the hoses I can reach when I do the wp later on.
