One of the most overlooked factors affecting one’s driving experience would certainly be the temperature of the vehicle.

If your car is too cold when you try to start it up, you will probably encounter some issues when you try to start it up.

If it’s too hot in your car, the engine can overheat, causing additional problems.

Now, while almost all vehicles are routinely equipped with a thermostat (which regulates the flow of coolant to your car’s system), it’s also useful to have a thermometer in the passenger area, too.

The thing is, a thermometer will let you know exactly what the temperature inside the vehicle is, so you can fine-tune the cooling or heating system. This, in turn, will help you save energy.

In this article, we’ve prepared a list of five different models of thermometers that you can use inside your vehicle’s passenger area or for measuring the temperature of the motor and other components. Also, we’ve ventured to answer some of the most frequently asked questions regarding thermometers in cars, so you can have an easier time finding the perfect thermometer for your needs.

Without further ado, here’s the deal.

Thermometers are useful contraptions that can come in handy in a wide variety of situations. For example, if you need to check the water temperature in a bowl with a plant in it you hope to grow, or see how hot the milk is for your baby – one of these contraptions can be a lifesaver.

Of course, owning a thermometer is a must if you own a car or some other vehicle.

The reason we mentioned that stuff in the first paragraph is that this model from KETOTEK can be a great option for a person looking for a thermometer they can use both for measuring the temperature in their vehicle and measuring the temperature of some other surface or matter.

Setting this model up is a piece of cake, as it comes with a USB power cord, so all you need to do is stick it to a nearby USB port or even a computer and this thing will boot up, so to speak.

Frequently Asked Questions:

1) Are car thermostats accurate?

More often than not they tend not to be.

The thing is, the thermometer that is inbuilt in cars are not thermometers, but thermistors, which is a special subtype of a thermometer.

Since thermistors measure temperature by measuring the changes in resistance to electrical current rather than featuring something like a mercury-based system in those old thermometers, they tend to be inaccurate if they are placed somewhere where they can pick up multiple different readings. (To the front of the car, for example, where the temperature of the ground plays a role.)

That said, you can always install an additional digital thermometer to get a more accurate reading inside or outside of your car.

2) What is the best place to put a thermometer in your car?

If you want a regular thermometer for the inside of your car, you can simply place it on your dashboard. As long as the heating or cooling vents are not too close to it, you should be able to get a pretty accurate reading of what the temperature inside your car is.

3) Why is my car temperature high?

There are three main reasons why your engine temperature gets high:

  • Your engine is in poor condition and it’s overheating (especially if it’s a hot day),
  • Your cooler is not working properly, or there’s not enough coolant inside it, or
  • The thermostat (or thermistor) that measures the temperature is off.

4) Why is my car overheating when the coolant is full?

Other than some sort of imminent engine failure (if you forgot to add engine oil, for example), a common reason why your temperature gauge suggests your engine is overheating is that the thermostat is damaged or kaput.

So, before you do anything else, if you get a high-temperature reading for your car’s engine, check if the thermostat is working properly first.

All in all, whether you want to measure the temperature of your car’s engine with a thermometer with a probe, or are just interested to know what the temperature inside and outside of your car is, obtaining a thermometer for your vehicle would be a valuable purchase.
