Hi,
Replacing the thermostat isn't too difficult to do. Make sure you have a place to put the old coolant after it's drained. You don't want any animals drinking it.
To get you started, here is a link that explains how in general one is replaced. You can use this as a more detailed guide when doing the job. The directions specific to your vehicle are attached in the pics below.

If you look at the pics below, the location of the thermostat is indicated.
I hope this helps. Let me know if you have other questions.
Take care,
Joe
