How does an automotive thermostat work?
The thermostat is basically a valve between the engine and the radiator. When the coolant in the engine gets too hot, this valve opens, letting it pass to the radiator where it will cool down. If it is not heated, the thermostat stays closed, allowing the coolant to continue circulating inside the block.
Which car thermostat is best?
A 180-degree thermostat is better for engine efficiency—aka better fuel mileage and decreased emissions. A 160-degree thermostat is designed to maintain a lower engine operating temperature, which tends to make a little bit more horsepower and torque.
What happens when the thermostat goes out in a car?
Because your thermostat controls temperature of fluids from the radiator hose, a bad thermostat will cause your car to overheat. If the thermostat becomes stuck in the closed position, antifreeze doesn’t flow from the radiator, causing overheating.
How long does a car thermostat last?
10 years
However, most car experts recommend car thermostat replacement after 10 years. However, this is an optimistic number. Thermostats are more likely to stop working much earlier than a decade. Some factors that induce an early thermostat failure include harsh weather, rough driving, bad engine or thermostat parts.
Why is my car overheating with a new thermostat?
You could be having a problem with your radiator being clogged up. This will cause the flow of the coolant in the system to be restricted, causing the truck to overheat. A clog in the heater core could also cause this problem. The most likely cause is a clogged radiator.
Will a lower thermostat help overheating?
A low-temp thermostat gives the cooling system a head start. This will help to prevent Engine Detonation and overheating.
How do I know if my thermostat needs to be replaced?
Signs You Need a New Thermostat
- Heating or cooling system will not turn off or on.
- The temperature reading is incorrect.
- Recent spike in your energy bill.
- Frequent temperature fluctuations.
- Thermostat is 10 years old or older.
What does an automotive thermostat do?
The thermostat in most cars is about 2 inches (5 cm) in diameter. Its job is to block the flow of coolant to the radiator until the engine has warmed up. When the engine is cold, no coolant flows through the engine. Once the engine reaches its operating temperature (generally about 200 degrees F, 95 degrees C), the thermostat opens.
What direction does an automotive thermostat go?
This is a trick that if you remember it you will never install a thermostat in the wrong way, and you’ll always be able to bleed the cooling system easily. The shorter end (Arrow B) of the thermostat always points toward the radiator hose, and away from the engine.
What is the best car thermostats?
“We find that the best smart thermostats are the ones that use or take advantage of the latest technology, like touch screens and sensors and GPS,” says John Galeotafiore, who manages thermostat testing at CR. “Combining this with a well-designed user interface and the ability to sense and learn by itself is what makes a great smart thermostat.”
What is the function of a thermostat in a car?
– Preparation: Disconnect the negative battery cable and drain some of the coolant from the system. This will prevent any spillages when testing. – Removal – Remove the upper radiator hose. This will then allow you to remove the thermostat housing and finally the thermostat itself. – Testing – Fill a pot with cold water and insert a thermometer.
