For a 2010, you're about due for a coolant change anyway. It's 5 years or 100,000 miles, whichever comes first. Assuming yours was built in '09 it should have new coolant sometime this summer or fall.
At $50 it's practically a no-brainer. I agree with JKM asking about the t-stat; they don't last forever, and it's a lot less work to do it while the coolant's out. That should save you some labor fees.
