Here are bad car thermostat symptoms you should know.
Being a heat-sensitive control device positioned at the radiator hose, a faulty car thermostat can make your car swelter. Once the engine temperature reaches proper operating temperature, the thermostat will regulate the heat by opening to let coolant flow into the engine. On the other hand, if the device is stuck closed, antifreeze will not be able to flow from the radiator, provoking car overheating. Therefore, when this happens, there is a strong possibility that your car thermostat has broken down.

Overheating can also result in other problems with cooling system including leaking hoses.
When the thermostat is trapped into an open setting, it may cause engine under heating. The open setting here means that the coolant will be continuously flowing into the engine without reference to whether it gets the normal temperature. In lieu of ending up too hot at all times, the engine will then become too cool. Thence, if you’ve been driving for a while and your car temperature gauge needle is still staying close to the bottom, you should have the thermostat checked.
3. Temperature fluctuations
The fluctuation in temperature is also one of malfunctioning car thermostat symptoms. In this case, the thermostat will not get stuck, yet the temperature gauge will still tell you false readings, leading to issues with regulation. The temperature of the engine will vary eccentrically while the coolant is stopped from moving in the usual way.

4. Poor engine performance
The temperature fluctuations will eventually affect the engine performance. In detail, your gas mileage could be reduced and worse still, the damage can cost a small fortune to fix.
In the end, as soon as you notice any of defective car thermostat symptoms above, don’t hesitate to open the hood and look over the thermostat. In case you’re forced to replace it, visit any local car parts store to buy a new one. As stated earlier, the repair is just a pushover. Watch this video for details instructions.
