Nairobi traffic can push an overheating problem to the surface quickly — especially when you’re stuck for long periods on routes like Thika Road, Waiyaki Way, or Mombasa Road. Acting fast and correctly can prevent expensive engine damage.
1) Do this immediately (first 60 seconds)
- Turn off the A/C and reduce engine load.
- Turn on hazard lights to alert other drivers.
- Pull over safely as soon as possible (shoulder, petrol station, safe parking).
- Turn off the engine and allow it to cool.
2) What NOT to do
- Do not open the radiator cap while hot — it can cause burns.
- Do not pour cold water on a hot engine — it can crack components.
- Do not keep driving “to reach a garage” if the gauge is already in the red.
3) After the engine cools (safe checks)
Only do the following after the engine cools down properly:
- Check if there’s visible coolant leakage under the car.
- Check the coolant reservoir level (not the radiator cap).
- Check if the radiator fan is running when the engine warms up again.
4) Common causes of overheating
- Low coolant due to leakage
- Faulty radiator fan
- Blocked radiator
- Thermostat issues
- Water pump problems
If overheating returns quickly after restart, there’s visible leakage, or steam keeps coming out, towing is safer than risking engine damage.
Frequently Asked Questions
What should I do first when my car overheats?
Turn off the air conditioner, switch on hazard lights, and safely pull over. Turn off the engine and allow it to cool.
Should I open the radiator cap when the car is hot?
No. Never open the radiator cap while hot because the system can be under pressure and may cause burns.
When is towing the safer option for an overheating car?
If overheating keeps happening, there is coolant leakage, steam is coming from the engine, or temperature rises immediately after restarting, towing is safer than driving.
