That “boat-like” dashboard symbol is almost always the engine coolant temperature warning.
🚗 What the symbol actually is
It usually looks like:
- a thermometer over wavy lines (water)
👉 The “waves” are what make it look like a boat
🌡️ What it means
- Red light → engine is overheating (serious)
- Blue light → engine is cold (normal at startup, not dangerous)
⚠️ Why it matters
If the red warning is ignored, it can lead to:
- engine overheating
- head gasket damage
- warped engine parts
- complete engine failure (very costly)
🚨 What to do immediately (if red light appears)
- Pull over safely
- Turn off the engine
- Let it cool down completely
- Check coolant level (only when cool)
- Look for leaks under the car
🚫 What NOT to do
- Don’t open the radiator cap while hot (burn risk)
- Don’t keep driving with the light on
🧠 Common causes
- Low coolant
- Radiator leak
- Faulty thermostat
- Cooling fan failure
🧠 Bottom line
That “boat-like” symbol is a cooling system warning. If it turns red, treat it as urgent—it’s there to prevent serious engine damage.
