Could be,
low on coolant (a leak in the system),
a stuck closed thermostat,
a faulty temp gauge sending unit,
a bad head gasket or cracked head (worst case scenario).

normally the gauge should be in the middle.(between hot and cold) that is concider operating temp.
Low on coolant or a sticky thermostat, replace it.
In the engine block of a vehicle, the part which is responsible for sending information to the temperature gauge is called the temperature gauge sending unit.
Make sure it is full of coolant. There probably is a small leak causing the smell. Check it cold as sometimes it leaks cold but not hot.
