You are right…. when your car’s engine temperature is running hotter than it is suppose to it will start to create an odor.  The engine is designed to operate at a range of 180 F to 210 F. To help it stay within this range, the engine uses a thermostat. 

The thermostat responds to changes in the radiator’s   coolant temperature.  This happens when a valve opens or closes to control coolant flow between the radiator and the engine. The valve operates through a wax type capsule.

The thermostat starts in a closed position when you start your car. As coolant temperature rises, it begins to open.  As the thermostat opens, it allows hot coolant in the engine to flow into the radiator, while the water pump pushes lower-temperature coolant from the radiator into the engine. When this lower-temperature coolant reaches the thermostat, the expanding fluid begins to contract, closing the thermostat’s valve.

A failed thermostat will prevent the engine from operating within its ideal temperature range and affect its performance or making your car inoperable.  You will want to have your vehicle looked at by an auto technician for an accurate diagnosis soon.
