Trying to do my own flush @ 110,000mi. I know to change the lower tstat but those with experience, do you also replace the water control valve?

2011 Versa 1.8L with CVT transmission, are you talking about that component?

Are you concerned your thermostat is bad?? You can test it by heating up some water (on a stove) with a thermometer and seeing when it opens.
Yes, that engine. They way I understand it is that it is wise to replace the thermostat if it is 10+ years old and you are going to do a coolant flush.
Thank you. I am a novice when it comes to doing my own maintenance so I thank you for the advice. I think I will do as you say and if it becomes an issue, I can always reuse the coolant if it is relatively new.
