Owning a Mercedes G63 is a statement of luxury, performance, and style. However, like all high-performance vehicles, the G63 is susceptible to certain maintenance issues. One common yet critical problem that owners face is a coolant leak. Left unattended, a coolant leak can lead to engine overheating, performance issues, and expensive repairs.
At Car Garage Expert Dubai, we specialize in diagnosing and repairing Mercedes G63 coolant leaks. Our certified technicians combine experience, advanced tools, and genuine parts to restore your vehicle to peak performance.
This guide explores everything you need to know about Mercedes G63 coolant leak repair, from identifying symptoms to choosing the right service in Dubai.
What is a Coolant Leak?
A coolant leak occurs when the liquid responsible for regulating your engine’s temperature escapes from the cooling system. The Mercedes G63 uses a high-performance cooling system designed to maintain optimal engine temperature under extreme conditions.
Primary Functions of Coolant:
- Prevents engine overheating
- Protects against corrosion
- Maintains efficient engine performance
- Ensures smooth climate control operation
A leak can compromise all these functions, leading to engine damage if not addressed promptly.
Common Causes of Mercedes G63 Coolant Leaks
Understanding the root cause of a coolant leak is essential to prevent recurring issues. In the Mercedes G63, common causes include:
- Damaged Radiator: Cracks or corrosion can cause coolant to seep.
- Faulty Water Pump: A worn-out pump may leak under pressure.
- Blown Head Gasket: A serious issue that can mix coolant with engine oil.
- Loose or Broken Hoses: High pressure and heat can damage hoses over time.
- Thermostat Housing Leaks: Rubber seals can deteriorate and cause leaks.
- Coolant Reservoir Damage: Cracks or leaks from overfilling.
Each cause requires a specific diagnostic approach, making professional repair essential.
Symptoms of a Coolant Leak in Mercedes G63
Recognizing a coolant leak early can save you from costly repairs. Common signs include:
- Engine Overheating: Rapid temperature rise on the dashboard gauge.
- Puddles Under the Vehicle: Green, yellow, or pink fluid beneath your car.
- Low Coolant Levels: Frequent need to refill the coolant reservoir.
- Sweet Smell: A noticeable sugary smell from leaking antifreeze.

Ignoring these signs can lead to engine failure, making timely repairs critical.
