Why Radiator Leaks Are Common in Nairobi and How to Fix Them
Radiator leaks are one of the most common cooling system problems Kenyan drivers face. With Nairobi’s traffic, dusty roads, and varying weather conditions, cars are more prone to overheating and radiator issues. Understanding radiator leaks in Nairobi helps you act fast and avoid costly engine repairs.
Common Causes of Radiator Leaks
1. Rust and Corrosion
Over time, moisture and poor-quality coolant cause rust inside the radiator, leading to leaks.
2. Road Debris and Damage
Stones and debris from rough Nairobi roads can puncture the radiator, causing leaks.
3. Worn Out Hoses and Clamps
Aging hoses crack and loosen, allowing coolant to escape.
4. Poor Maintenance
Skipping coolant changes or using plain water instead of proper coolant weakens the radiator.
5. Overheating in Nairobi Traffic
Prolonged idling in heavy traffic strains the cooling system, worsening small leaks.
