Dubai’s traffic can be relentless, with long hours spent in stop-and-go conditions under the scorching sun. Extreme heat & traffic strain your car’s cooling system, especially the radiator. A faulty radiator can cause overheating, leading to expensive repairs & unexpected breakdowns.
The good news is that you can prevent this from happening by spotting radiator problems early. In this blog, we’ll discuss the common signs of radiator issues and how to address them before they turn into major headaches.
Why Is the Radiator So Important?
Your car’s radiator plays a crucial role in maintaining the engine’s temperature. It circulates coolant through the engine, absorbing excess heat and preventing overheating. If the radiator fails, the engine temperature can rise dangerously high, causing damage to critical components.
Since Dubai’s high temperatures already put extra strain on your engine, ensuring your radiator is in top condition is essential.
Common Signs of Radiator Problems
Recognizing early signs of radiator trouble can save you from expensive repairs and unexpected breakdowns. Here are the key warning signs to watch for:
1. Engine Temperature Running Hot
If you notice your temperature gauge creeping up higher than normal, your radiator might not be cooling the engine properly. While Dubai’s climate naturally leads to higher engine temperatures, a consistently high reading is a red flag.
2. Coolant Leaks
Coolant leaks are one of the most obvious signs of a radiator problem. If you spot green, orange, or pink puddles under your car, your radiator or one of its hoses may be leaking. Even a small leak can cause your car to overheat over time.
3. Rust or Corrosion on the Radiator
Over time, rust and corrosion can build up inside your radiator, leading to blockages and leaks. If you notice brown or reddish stains around the radiator, it may be time for a professional inspection.
4. Coolant Levels Dropping Quickly
If you constantly need to top up your coolant, there could be a hidden leak or an internal issue with the radiator. Ignoring this sign can lead to overheating and serious engine damage.
5. Sludge in the Coolant Reservoir
Coolant should always be a bright and clear color. If it appears thick, sludgy, or discolored, it may indicate a problem within the radiator, such as contamination from rust or oil mixing with the coolant.
6. Overheating Warning Light
Most modern cars have an overheating warning light on the dashboard. If this light turns on, it means your engine is running too hot, and you should stop the car immediately to prevent further damage.
7. Steam Coming from the Hood
If you see steam rising from under your hood, your engine is overheating, likely due to radiator failure. This is a serious issue and requires immediate attention.
Preventive Maintenance to Avoid Radiator Problems
Routine maintenance is the best way to prevent radiator problems. Here are a few simple steps to keep your cooling system in good shape:
Regularly Check Coolant Levels
Ensure your coolant reservoir is always at the recommended level. If it’s low, top it up with the correct type of coolant specified in your car’s manual.
Inspect for Leaks
Check under your car regularly for any signs of coolant leaks. Catching a small leak early can prevent major issues later.
Flush the Radiator Periodically
Over time, coolant can break down and lose its effectiveness. Flushing the radiator at recommended intervals (typically every 30,000 to 50,000 km) removes buildup and ensures smooth coolant circulation.
Keep the Radiator Clean
Dust and debris can clog the radiator fins, reducing cooling efficiency. Cleaning the radiator with compressed air or water can help maintain proper airflow.
Monitor the Temperature Gauge
Make it a habit to glance at your temperature gauge while driving. If you notice fluctuations, have your cooling system inspected.
Replace Worn Hoses and Radiator Caps
Cracked or brittle hoses can cause leaks and reduce coolant flow. Similarly, a faulty radiator cap can lead to pressure issues. Replacing these parts when necessary can prevent serious problems.

Frequently Asked Questions
In Dubai’s extreme heat, flush your radiator every 30,000–50,000 km or every 2–3 years. Frequent traffic or dirty coolant may require earlier flushing to prevent overheating & ensure optimal performance.
In Dubai’s heat, use a high-quality, long-life coolant with anti-corrosion properties. Choose an ethylene glycol-based 50/50 premix. Some manufacturers recommend HOAT or OAT coolants for enhanced engine protection & performance.
Driving with a leaking radiator is dangerous and can cause overheating, engine failure, or a blown head gasket. If you spot a coolant leak, stop immediately and repair it quickly.
Radiator leaks often result from corrosion, worn hoses, or a faulty cap. Overheating, a blown head gasket, physical damage, & improper coolant use can worsen leaks. Regular maintenance helps prevent issues.
If your car overheats in traffic, causes may include a faulty radiator fan, low coolant, clogged radiator, thermostat failure, or a worn water pump. Regular maintenance helps prevent issues.
