What Is a Coolant Leak and Why It Matters
Coolant, also known as antifreeze, is vital to your Mercedes AMG’s cooling system. It circulates through the engine and radiator to absorb and dissipate heat. A Mercedes AMG Coolant Leak Repair occurs when this sealed system is compromised, leading to loss of fluid and potentially causing the engine to overheat.
Unchecked coolant leaks can lead to:
- Engine overheating
- Blown head gaskets
- Engine block cracks
- Complete engine failure
Common Causes of Coolant Leaks in Mercedes AMG Vehicles
Mercedes AMG models, due to their high-performance engines and compact engine bays, are prone to specific coolant system issues, including:
-
Cracked Radiator
Common due to pressure buildup and heat stress, especially in AMG models with turbocharged engines. -
Worn Out Water Pump Seals
Over time, the seals around the water pump may degrade, especially in high-mileage AMG vehicles. -
Faulty Radiator Hoses
Aging hoses become brittle and may develop cracks or split due to intense heat exposure. -
Defective Expansion Tank
Expansion tanks in some AMG models are prone to cracking or cap failure. -
Leaking Heater Core
More rare but serious, this can leak coolant into the cabin and reduce heating efficiency.
Signs Your Mercedes AMG Has a Coolant Leak
Detecting a coolant leak early can save thousands in engine repair costs. Here’s what to look for:
- Puddle of green, orange, or pink fluid under your car
- Warning lights or coolant temperature gauge spikes
- Steam coming from under the hood
- Sweet, syrupy smell near the engine
- Engine running hotter than normal
- Coolant reservoir constantly low
If you notice any of these signs, book a diagnosis with Car Garage Expert right away.
The Dangers of Ignoring a Coolant Leak

- Cylinder Head Warping

In Dubai’s climate, engine overheating can occur within minutes—making quick intervention essential.

Why Dubai Climate Makes Coolant Leaks Worse
Dubai’s extreme summer temperatures (often exceeding 45°C) put extra strain on your cooling system. Leaks that might be minor elsewhere can quickly become catastrophic in this environment. The high heat causes:
- Faster evaporation of coolant
- Increased engine pressure
- Thermal expansion leading to cracked components
Routine coolant system checks are essential in Dubai for AMG owners.
