After the initial repair, James found what caused my belt to go faulty in the first place. In a non pushy way he showed me where the problem was and the possible fix for it or I had the option to leave it as it was. I knew it had to be an issue because I had placed coolant in the car days prior and it was already gone out. I'm glad I took his advice and got the water pump replaced before it became a major issue later on.

All about Thermostat Replacement

A thermostat is part of the cooling system that regulates the temperature of the coolant in the engine. The thermostat is a metal valve that has a temperature sensor built in. It can either be open or closed. When the thermostat is closed, it keeps the coolant in the engine. When the engine gets to a predetermined temperature, the thermostat opens allowing coolant to circulate. The circulation of coolant prevents the engine from overheating. If the thermostat fails to open, the car will overheat. If the thermostat fails to close, the engine may never reach the optimal temperature (~220F). The thermostat opens and closes many times when the car engine is running. It is the most common component in the cooling system to fail, causing the car to overheat.
