Why does my car overheat when sitting in traffic?
If the coolant level is low, that tells you there is a leak somewhere in the system. If there isn’t enough coolant in the system, the engine can easily start to overheat while you sit at a stoplight or in traffic.
What does it mean when your car goes from cool to hot?
Cars overheat most often in very hot weather. Although hot weather is the most common cause of overheating, many other factors can cause the same problem. If your vehicle overheats in traffic in normal weather, one of the following may be the culprit: The water and coolant and water level in the radiator is low.
What happens when a thermostat goes bad?
Because your thermostat controls temperature of fluids from the radiator hose, a bad thermostat will cause your car to overheat. When the engine temperature has reached the operating level, it should allow coolant to flow to the engine and regulate the heat.
Why does my car heat up when I’m not driving?
If you have an electric cooling fan that isn’t coming on, this can cause your engine to overheat. This fan draws cooler air through your radiator when your car isn’t going fast enough to do the job naturally. You can test this by letting your car idle long enough for the engine to heat up.
What causes a car to overheat when idling?
That said, some of the the basic things you can check when your car overheats at idle include: The coolant level. Only check when the engine is cool. Low coolant can cause overheating. Air bubbles in the cooling system can also cause issues. Only use the specified type of antifreeze to top off the system. Fan belt problems
Why does my car blow cold air when the car is moving?
My car has 165 miles. My car has an automatic transmission. When the car is moving, versus stopped, there is more air flow over the condenser (the heat exchanger in front of the radiator) and that airflow is essential to system operation.
Why does my car overheat but no water flow?
If the engine starts to overheat but you don’t see water flow, then have an assistant rev the engine up for a moment. If water doesn’t move, or suddenly rushes into the radiator, then you probably have a problem with the thermostat or water pump, or an internal water leak.
Why does my car heat up when I idle?
As you may know, the heater core is a small radiator like unit that circulates the hot coolant from the engine through the heater core which then uses this warm coolant to heat the inside of the car with the help of the blower motor that blows the warm air through the vents inside the car.

What happens if your car engine is too hot?
An overheating engine is a big problem. Engines that run too hot are at risk of complete destruction, as the engine block itself can warp when there’s too much heat.
Why does my car overheat all the time?
Intermittent overheating problems can also be caused by low coolant, air in the cooling system, a bad coolant temperature sensor, or even a faulty gauge. Before you proceed, it’s important to remember that some things can’t be checked when the engine is running or right after you shut it off.
