What does the temperature of the coolant mean?
If the temperature gauge reads high, your car could be leaking coolant or have a bad water pump. The temperature gauge in your vehicle is designed to indicate the temperature of your engine’s coolant. This gauge will tell you if your engine’s coolant is cold, normal, or overheating.
How can I find out the coolant temp in my car?
If you have an OBDII scanner, you may even be able to graph coolant temperatures in your app and track them that way. The best place to start in comparing your vehicle’s normal engine coolant temperature to see if it’s correct is with your thermostat setting.
What causes an engine temperature gauge to stay on cold?
Reasons Why your Engine Temperature Gauge Stays on Cold 1. Faulty Engine Coolant Temperature Sensor 2. Faulty Gauge/Cluster 3. Broken wires to the sensor or to the gauge 4. Bad Thermostat 5. Corrosion in connectors 6. Air in the coolant system 7. Broken engine control unit
What does the coolant temperature sensor do on an engine?
The engine coolant temperature sensor’s job is to measure the coolant temperature for the engine control module. With this information, the engine control module adjusts the air-fuel mixture depending on the temperature. This article will discuss the most common symptoms of a bad coolant temperature sensor, location, replacement cost.

Is it normal for a car temp gauge to be cold?
If your car has sat immobile for a few hours, it’s normal for the temperature gauge to show a cold reading for a few minutes after start-up. Of course, it may take a bit longer for it to come up to a normal temperature in extremely cold temperatures.
What does the temperature of the engine tell you?
Average rating from 17,638 customers who received a Change Oil and Filter. The temperature gauge in your vehicle is designed to indicate the temperature of your engine’s coolant. This gauge will tell you if your engine’s coolant is cold, normal, or overheating.
What to do if your car’s temp is too hot?
If this still doesn’t work, pull over on the side of the road, turn off the engine, open the hood carefully, and wait until the vehicle cools down. Never open the radiator cap while the engine is hot – coolant can spray and burn you. Once the vehicle has cooled, take the car to a mechanic right away so they can diagnose the problem.
How many miles do you have to drive to turn off Check Engine light?
You have to drive 50 to 100 miles in several individual trips until the system reads the status of all the components again. “Several trips” means that you shut off the engine and start another trip.
What happens if you open the radiator cap?
Never open the radiator cap while the engine is hot – coolant can spray and burn you. Once the vehicle has cooled, take the car to a mechanic right away so they can diagnose the problem.
How to change coolant without causing engine to overheat?
Check your car owner’s manual or vehicle repair manual. The purge valve will expel any air that gets into the system after adding the new coolant. This will prevent the formation of air bubbles or hot pockets inside the engine that cause overheating. Another way to purge air from the system is to use what I call the jack stand method.
What happens if you remove the radiator cap on a hot engine?
Never attempt to remove the radiator cap off of a hot engine. The radiator cap is designed to pressurize the system so that the water doesn’t boil as easily. Removing the cap from a hot engine will cause the coolant to start boiling and the steam will most likely burn you. Once the engine has cooled, check the overall fluid level of the coolant.
What causes coolant to boil on hot engine?
Removing the cap from a hot engine will cause the coolant to start boiling and the steam will most likely burn you. Once the engine has cooled, check the overall fluid level of the coolant. If the level is low, you can add just water temporarily so that you can drive somewhere to get the car checked out.
Is it safe to drive with the coolant temperature warning light on?
Is it safe to drive with the coolant temperature warning light on? While the car is still driveable, you run the risk of causing significant damage to the engine by letting it run too hot. As mentioned earlier, if the light comes on, you should pull over as quickly and safely as possible.
