Where is a thermostat in Chevy Beretta v6?

The thermostat in a Chevy Beretta V6 is located on the engine, usually at the back of the engine block near the water pump. It's often tucked away and can be difficult to access. You'll likely need to consult a repair manual specific to your Beretta's year and engine to get a precise location and understand the removal process. A repair manual with diagrams will be very helpful.
