What does the thermostat on a Chevy Impala do?

Designed to open when the coolant reaches 195 degrees fahrenheit, the Chevrolet Impala thermostat is a corrosion resistant design with a unique V-notch that measures the amount of coolant needed at any one time, allowing just enough to control the temperature of the Impalas engine.

Why is the thermostat closed when I start my car?

The fan motor (or fan motors) are tasked with keeping the engine below 227° Fahrenheit. When you start your vehicle, the thermostat is closed, thereby keeping the coolant from circulating to the radiator. This allows the engine to warm up faster.

What happens to coolant when the thermostat is opened?

As the coolant circulates in the engine only, its temperature increases and when it reaches 190° F, the thermostat opens. With the thermostat now open, the coolant can now circulate between the radiator and the engine. Even tho’ the thermostat has opened, the temperature of the coolant will continue to increase.

What should the thermostat be for a gas engine?

This temperature range is between 190° to 225° Fahrenheit (87° to 107° Celsius). The reason for this is that the cooler the engine is, the more gasoline it needs to keep running smoothly (and unfortunately, at these temps, it pollutes more).

The thick black hose runs from the side of your radiator and attaches to the top or side of your engine block with a tube clamp. Use a screwdriver to loosen the nut on the tube clamp and then pull the hose off of the engine. Set the end of the hose aside for now so you can access the thermostat housing on your engine.
