Try Item #1 first it is the easiest.
Then Check the small water pump belt, it is not the serpentine belt.
The next step is to either check the Block with the following block tester available from NAPA
The part number is 700-1006
or change the thermostat dealer cost about 60.00 AUTOZONE about 40.00 You will need to purchase the Gasket with which ever you purchase from.

I had written a detailed note and the system dropped it. I hope this helps. coolant system drawing is available from:
