Cooling system hoses 2016 XC60

[mlarsonatx]

Hi. I have had nothing but issues with all the hoses in my cooling system since I had it flushed. It’s been a can of worms that’s cost me $2000+. This connector is now leaking antifreeze also. The engine hasn’t overheated-yet-but I have to keep adding coolant to the reservoir because it’s triggering the sensor for the coolant being low. I know more than the average woman about cars. I grew up at my Dads shop and am able to change my own oil, do my brakes, replace an alternator, and recently replace the main battery and the alternate battery for the start/stop function. Is replacing this going to be too difficult for me to do on my own? If not, any ideas of potential cost? (My funds are currently pretty tight.). I drive an average of 300 miles/week for my job as a PT seeing people at their homes. I can’t be without my car. Any ideas and or help are much appreciated. See pics please. Thank you in advance.
