REPLACING A THERMOSTAT

2004 Mazda 3 • 2WD Automatic • 114,000 miles

How easy is it to change out a thermostat on a 2004 mazda 3 2.0, and where can I find a schematic. Will I need any special tool. What are the dangers of doing it myself, and how long should it take. My experiance is that I do 90% of all auto maintenance
