The role of the thermostat is to control the flow of hot water through the radiator. The thermostat is integrated and mounted on the engine block, adjusting the coolant flow towards the radiator. … The primary function of a thermostat is to maintain a minimum operating temperature in the car’s engine.
The cost of getting a thermostat replaced in a car is about $200 to $300 on average. Of course, this will also greatly depend on the make, model, and year of the vehicle that you’re driving.
Because your thermostat controls temperature of fluids from the radiator hose, a bad thermostat will cause your car to overheat. When the engine temperature has reached the operating level, it should allow coolant to flow to the engine and regulate the heat.
Most automobile mechanics will tell you it is not a good idea to drive your car without a thermostat installed. … If your thermostat becomes stuck in the closed position, though, this will cause your engine to overheat and make driving your car impossible.

the most noticeable issues occur when the thermostat gets stuck in either the open or closed position. a malfunction can result in a trouble code, generated by the engine’s computer, which can turn on your check engine light.
Thermostat stuck open: When the thermostat is stuck open, the engine temperature drops below normal when driving, especially on the highway in cold weather. A stuck-open thermostat can also cause lack of heat from the heating system. The Check Engine light may come on too.

Look for and address simple reasons why the thermostat isn’t getting power, such as dead batteries or a tripped breaker or blown fuse in your main electrical service panel. If you’re certain it’s receiving power, shut off the thermostat breaker in order to safely take off the cover and examine the inner components.
If the engine gets hotter than the optimum temperature, you know it won’t be able to sustain the heat for more than 10 minutes and will eventually die. However, when your engine runs below the optimum temperature, your engine will die slowly yet certainly — it’s a death by a thousand cuts.
An Integral Part of the Cooling System & How It Works
When the engine is cold, the coolant will not flow through the engine. As the temperature rises, however, the thermostat slowly begins to open. By the time the engine reaches approximately 200 degrees Fahrenheit, the thermostat will be open entirely.
Can I Still Drive with a Bad Thermostat? The easy answer to this question is no. While your car may be physically able to move and get you from Point A to Point B, you will want to refrain from operating your vehicle. This can lead to more parts of your vehicle being damaged, especially if the engine is overheating.
