<human>: How can I tell if my car's engine is about to overheat?
<bot>: The best way to tell if your car's engine is about to overheat is by regularly checking the temperature of the coolant and oil. If either one of these are above their normal levels, you should take your car to a mechanic as soon as possible for an inspection. Additionally, listening for unusual noises coming from the engine or seeing smoke coming from under the hood could be signs that the engine is overheating.
