AI Analysis Summary

The car's engine is overheating, indicated by the temperature gauge in the red zone and visible steam from under the hood. This is a critical situation requiring immediate attention to prevent severe engine damage.

Problème signalé

My car's temperature gauge is climbing into the red zone, and I've seen steam coming from under the hood. I pulled over immediately. I'm worried about serious engine damage.

Questions

5 questions
Q1

When did you first notice the temperature gauge rising, or did it happen suddenly? (ID: 1620)

It happened pretty suddenly. I was driving on the highway, and the temperature gauge was in its normal spot, maybe a little below the halfway mark. Then, within a few minutes, it started climbing rapidly. I saw the needle hit the red, and then I noticed the steam coming from under the hood, which is when I pulled over.

Q2

Have you recently had any work done on the cooling system (e.g., coolant flush, hose replacement)? (ID: 1621)

No, I haven't had any work done on the cooling system recently. The last time I had the car serviced was about three months ago for an oil change, and they didn't mention anything about the coolant or the cooling system.

Q3

Do you notice any coolant leaks under the car when it's parked? (ID: 1622)

Yes, I did notice a small puddle under the front of the car when I first pulled over. It was a greenish-blue color, which I assume is coolant. It wasn't a huge amount, but it was definitely there.

Q4

Is the heater inside the car blowing hot air, or is it cold? (ID: 1623)

That's a good question. Before I pulled over, I had the heat on because it's a bit chilly out. I remember it was blowing warm air, but I wasn't paying super close attention. Now that I'm stopped, I haven't tried turning the heat on again.

Q5

Have you checked the coolant level in the reservoir (when the engine is cool)? (ID: 1624)

Yes, I checked the coolant level in the reservoir this morning after the car had been sitting for a few hours. It was definitely below the 'MIN' line, almost empty. I'm not sure if it was like that before, but it's very low now.

Low Coolant Level

90%

A significant leak or evaporation of coolant can lead to insufficient fluid to dissipate engine heat, causing rapid overheating.
