Nigeria’s hot weather can be punishing—not just for humans, but for cars too. One of the most common issues Nigerian drivers face, especially during the dry season, is car overheating. Understanding why it happens, how to prevent it, and what to do when it occurs is essential for every driver. In this blog post, we’ll break down everything you need to know about car overheating in the Nigerian climate.
What Is Engine Overheating?
Engine overheating happens when the temperature of your car’s engine exceeds the normal operating range. Modern engines are designed to run efficiently at a certain temperature, usually between 90°C and 105°C. Going beyond this range can cause serious damage.
Common Causes of Car Overheating
Low coolant levels: Coolant helps regulate engine temperature. If it’s low, your engine can overheat quickly.
Leaking radiator or hoses: Leaks reduce coolant levels and cause pressure loss.
Faulty thermostat: A stuck thermostat can block coolant flow, trapping heat in the engine.
Thermostat
Broken water pump: The water pump circulates coolant. If it fails, overheating is almost guaranteed.
Water pump
Clogged radiator: Dirt and debris can block airflow, preventing heat from escaping.
Clogged radiator
Driving in traffic for long periods: Especially common in Lagos or Abuja, idling in traffic reduces engine cooling efficiency.
Using the wrong coolant or water: Regular tap water can cause scale buildup and corrosion.
Signs of Engine Overheating
Recognizing the signs of engine overheating early can save your car from serious damage. Watch out for these symptoms:
Temperature gauge rising above normal
Warning lights on the dashboard
Steam or smoke coming from under the bonnet
Strange smells, like a sweet smell from coolant or a burnt oil odor
Ticking or knocking sounds from the engine
Reduced engine performance or the car going into limp mode
Coolant leaking under the vehicle
Effects of Engine Overheating
Overheating your engine can lead to:
Warped or cracked engine cylinder head
Blown head gasket
Damaged pistons and rings
Coolant leaks and engine oil contamination
Total engine failure requiring expensive replacement
Preventive Measures to Avoid Overheating
Check coolant levels regularly: Ensure it’s topped up with the right mix of coolant and distilled water.
Inspect hoses and radiator: Look for cracks, leaks, or signs of wear.
Flush your cooling system: Do this every 12–24 months to remove buildup.
Monitor your temperature gauge: If it creeps up, pull over and investigate.
Don’t ignore the warning light: That temperature warning light is there for a reason.
Service your vehicle regularly: Get a mechanic to check your cooling system during oil changes.
What to Do When Your Car Starts Overheating
Turn off the A/C and turn on the heater: This can pull heat away from the engine temporarily.
Pull over safely and turn off the engine: Allow the car to cool down completely before opening the bonnet.
Do NOT open the radiator cap immediately: Wait at least 15–30 minutes. Opening it hot can cause serious burns.
Check coolant levels: If low and the engine is cool, top it up with the proper coolant or clean water temporarily.
Call a mechanic: If the problem persists or if there are leaks, don’t drive—tow the vehicle to a workshop.
Bonus Tips for Nigerian Drivers
Use sunshades and park under shade to reduce internal and engine bay heat.
Avoid bumper-to-bumper traffic for long periods during peak sun hours if possible.
Always carry an extra bottle of coolant or distilled water in your boot.
Watch for smoke, burning smells, or rapid gauge movement during long drives.
Conclusion
Overheating can ruin your engine, your day, and your wallet. With the Nigerian weather and road conditions, staying proactive is your best defense. Know the signs, keep your cooling system healthy, and don’t take risks when your car shows signs of distress.
