Intro: An overheating engine needs attention, but the cause is often simple.
1. Low coolant
Top up if it’s below the minimum.
2. Coolant leak
Look for puddles under the car.
3. Broken fan
If the fan doesn’t spin, the engine overheats in traffic.
4. Blocked radiator
Debris reduces cooling.
5. When to stop driving
If the temperature hits red, pull over safely.
Summary: Most overheating comes from low coolant or a faulty fan.
