The thermostat is like a valve that opens and closes as a function of its temperature. The thermostat isolates the engine from the radiator until it has reached a certain minimum temperature. Without a thermostat, the engine would always lose heat to the radiator and take longer to warm up. Once the engine has reached the desired operating temperature, the thermostat adjusts flow to the radiator to maintain a stable temperature.

What does a Catalytic Converter do?

A catalytic converter uses a chamber called a catalyst to change the harmful compounds from an engine's emissions into safe gases, like steam. It works to split up the unsafe molecules in the gases that a car produces before they get released into the air.

PCV valves are often times replaced during preventative maintenance;

The timing belt (not to be confused with a serpentine drive belt) is there to make sure that the movement of the camshaft or camshafts is synchronized with the movement of the crankshaft. Some vehicles have a timing belt, others have a timing chain; Timing belts have recommended mileage intervals for replacement, timing chains are usually "lifetime" but can stretch/break over time/mileage.
