Why can I hear my car engine?

What’s happening: You probably have a leak or crack in your exhaust system’s manifold. The roaring you hear is excess engine noise that would normally get silenced by the muffler. When your exhaust system fails, all of your engine’s sound waves and vibrations get channeled into the car.

Why is my car making a noise when the engine is off?

The “pinging” noise you hear is coming from the hot metal cooling under your car. As you drive, the engine and all the parts around it start to heat up and expand. Once you turn the car off, those metals will cool and contract. These tiny bumps produce the “pang” or “ping” you hear coming from your turned-off car.

Why do I hear bubbling when I turn my car off?

When the coolant cools and condenses, it moves into the radiator. Both of these can cause a gurgling or bubbling sound, and are completely normal.

Why does my engine sound like it’s boiling?

Hearing a bubbling or gurgling sound means that there’s fluid at work. The most common source of this sound is your coolant system, particularly if you have an expansion tank attached to your radiator. As the bubbles move with the flow of coolant, you hear the movement as a “gurgling”.

Should my coolant be bubbling?

Though it is completely normal to find bubbles in the overflow tank while the engine is not overheating, bubbles in the coolant could be the sign of a leak at the head gasket.
