I’ve often wondered why my vehicle’s temperature gauge spikes in heavy traffic. It returns to normal when I’m driving on the highway. This problem affects many drivers. It’s important to understand why it happens.
Overheating in traffic is a sign of trouble. We’ll look at why it happens more in stop-and-go traffic. We’ll also talk about how to stop it from damaging your car.
We’ll find out what causes this issue. This way, you can keep your car’s temperature safe. And avoid any damage to your vehicle.
The Science Behind Engine Cooling Systems
It’s important to know how engine cooling systems work. They keep the engine at the right temperature. This stops damage and makes the engine last longer.
How Your Engine’s Cooling System Works
The cooling system moves coolant through the engine. It takes heat away and sends it to the radiator. There, it gets cooled down.
This system has important parts. The water pump, radiator, and thermostat work together. They keep the engine’s temperature just right.
The Relationship Between Engine Speed and Cooling
Engine speed changes how well the cooling system works. When driving fast, the engine gets hotter. But the cooling system works better because of more air flow.
But in slow traffic, it’s harder for the cooling system. The engine speed changes a lot. And there’s less air flow.
The Role of the Radiator Fan
The radiator fan is very important. It helps air flow through the radiator, even when the car is stopped. It turns on when the engine gets too hot.
Today’s cars use electric cooling fans. They work better than old fans because they can be controlled more easily.
Why Your Car Engine Overheats in Traffic but Not on Highway
Engine overheating is common in stop-and-go traffic. But it rarely happens on highways. Let’s look into why this is.
