Question about 2003 Chevrolet Impala
The location of the thermostat also
The thermostat is located on the drivers side of the car under the throttle body assembly. just follow the hose to the thermostat housing. the easiest way to change it is to take off the throttle body. the throttle body gasket isnt expensive to replace

the best thing to get is the Haynes manual for your car at advanced auto or autozone or somewhere like that and the book will tell you how to take everything apart and put it back. i think the manual is about $16.00

There are two sets of 02 sensors on most cars today. On set is set directly behind the header, one on each side, if it is a V engine. This set is used for the engine's ECU to control timing as well as other variables. The other set is placed on a bung in your Catalytic converter. This 02 sensor is used for emissions purposes only.

There are two hoses that come from the radiator. The very bottom hose is conneted to the thermostat housing. Looking at the car from the front under the hood just below the first hose is another one same in diameter and there it is two bolts and you done.
