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.
When should I replace my thermostat?

Your Energy Bills Are Unusually High. Your Thermostat Gives Faulty Readings. Your Thermostat Doesn’t Respond to Settings Changes.
What are the signs of a bad thermostat?
Signs My Car’s Thermostat Is Going Bad or Has Failed Completely Odd Temperature Gauge Readings. Your temperature gauge should register cold when you first start your car and slowly build up to normal as the engine warms up. Air Temperature Changes. Coolant Leaks. Strange Sounds. Heater Problems.
How do you test a car thermostat?
Start your car’s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
How long is a thermostat good for?
They generally last about 10 years but can last longer depending on the make, model, and type of thermostat. Over time, these systems start to age and a thermostat may malfunction because of normal wear and tear, dust accumulation, wiring issues, and rusting.
How does a car act when the thermostat is bad?
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 do I know if my thermostat or water pump is bad?
You should be able to turn on your heating or cooling system from the thermostat, or change operation back and forth from heating to cooling. If you make changes at the thermostat and get no response whatsoever from your furnace, air conditioner, or heat pump, it could mean the thermostat is bad.
How do I know if my thermostat is working properly?
When a thermostat is working properly, it should display an accurate temperature of what it feels like inside your home. But if the room feels much hotter or colder than the display temperature, that means your thermostat can’t accurately measure the room’s temperature.
Is it OK to run a car without a thermostat?
Generally it should be ok to drive without the thermostat fitted, as it will only cause the engine to take longer to reach operating temperature. The thermostat is designed to allow the engine to reach ideal operating temperature as quickly as possible, so it would not be recommended to drive without it.
What can a bad thermostat do?
Effects of a Bad Thermostat A thermostat can fail in either the open or closed position. When the thermostat stays closed, the engine will begin to overheat, potentially leading to extensive engine and cooling system damage. When the thermostat stays closed, the engine will begin to overheat.
Will a bad thermostat throw a code?
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.
How long can I drive with a bad thermostat?
Yes, but not for very long. Thermostats typically “fail closed,” which means your coolant won’t circulate and you’ll overheat very quickly. I wouldn’t – even removing the thermostat is better than leaving a failed thermostat in place (it will take longer to warm up, but it won’t overheat on you!).
How do I know if my car needs coolant?
5 Signs That Your Vehicle Needs An Antifreeze/Coolant Service The temperature gauge reads hotter than normal when the engine is running. Antifreeze leaks and puddles beneath your vehicle (orange or green fluid) A grinding noise is coming from under the hood of your car.

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.
Is 160 or 180 thermostat better?
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.
