How do you know your car is overheating?

I was driving home from my soccer game the other night when my car started to smell hot. Luckily I was almost home, but I’m wondering if maybe my engine was overheating. How can I tell?

Yikes! Not the best way to cool off and relax after soccer. And you’re probably onto something as your car smelling hot is just one of the ways you can tell if your engine is overheating.
Here’s how you know your car is overheating:
  • Hot or sweet smell: The oil in the engine could be super hot and stinky, or your coolant could be leaking and causing the engine to overheat.
  • Steam: You might think there’s a fire under your hood, but it’s potentially just evaporating coolant. If it’s leaking, it may be turning to steam instead of cooling your engine.
  • Trouble accelerating: An overheated engine won’t work as it should, and it might start to crawl like it’s hot and dehydrated in a desert.
  • Temperature gauge: This gauge is located on your instrument panel and has a little hand that points toward blue or a “C” for a cool engine and red or an “H” for a hot one. If it’s stuck on the red, then your engine might be too hot.
  • Thumping or ticking: Your car can make these sounds if your coolant or oil is reaching too high a temperature.
If you have an engine that’s overheating, it’s important you pull over
as soon as it’s safe
to do so and turn the engine off. You’ll probably want to call a mechanic as driving with an overheated engine can cause damage.
