Hi,
Replacing the thermostat isn't a difficult job. You will need to drain the radiator. There is a petcock at the bottom that you loosen and the coolant will drain.
Also, two things to remember. There is a bleeder valve on the thermostat (some refer to it as a jiggle valve). Make sure that it is in the 12 o'clock position when you install it. If it isn't in that position, bleeding air from the system is more difficult. Additionally, make sure to lubricate the new o-rings with coolant before installing.
Here is a link that is a little more detailed. It explains in general how to replace one, but it isn't specific to your vehicle. You may find it helpful as a guide. The second pic shows the drain I mentioned. Yours may not be at the same spot, but it will be at the bottom of the radiator.

If you look at the pics below, I attached the directions specific to your vehicle.
Let me know if this helps or if you have questions.
Take care,
Joe
