My car is a 2007 Xfire base. I have read the excellent tutorial on this forum on how to do a coolant flush. But in the tutorial it speaks to replacing the thermostat. I am just curious for all of you guys who did a coolant flush did you go the extra step and change the thermostat.

I had just wanted to flush the coolant and dod not know a thermostat change factored into it. Will you guys weigh in as to whether this is necessary
