Here is the breakdown of the repairs:

Water pump replacement:
Labor 605
Material: Water pump $380; Multi-rib belt $80

Thermostat replacement:
thermostat with gasket $100 plus $200 for the labor.

Inspect the old pump impeller to see if any vanes came off, if they did they can lodge in the coolant manifold & cause overheating. Running the engine hot can crack the head. If it is already back together just watch for intermix or any coolant loss.
