Customer Complaint
I received a call from a customer in Franklin about their 2012 Mercedes-Benz ML350 leaking coolant and starting to overheat. They noticed the issue getting worse over a short period of time.
They mentioned:
Coolant puddle under the front of the vehicle
Temperature gauge rising higher than normal
Sweet smell from the engine bay
Warning message related to coolant level
These are common signs of a cooling system issue, often related to the radiator.
Diagnosis Process
When I arrived, I performed a cooling system inspection.
Findings:
Radiator was leaking coolant
Visible cracks and wear on the radiator
Coolant residue buildup around the front area
No major issues with hoses or water pump at the time
On vehicles like the ML350, radiator failure can happen over time due to heat cycles and material wear.
The Repair
Radiator replacement requires proper removal, installation, and system bleeding to ensure reliable cooling.
Steps performed:
Drained the coolant system
Removed the faulty radiator
Installed a new radiator
Reconnected hoses and components
Refilled coolant with proper mixture
Bled the system and checked for leaks
Tested engine temperature under operation
Total time on-site was about 2–3 hours.
Result
After the repair:
Coolant leak was completely resolved
Engine temperature remained stable
No warning messages
Cooling system operated properly
The customer was relieved to have it fixed before it led to more serious engine damage.
Why Radiators Fail
Radiators can fail due to:
Cracks from heat and age
Internal corrosion
Pressure buildup over time
If not addressed, a failing radiator can lead to:
Engine overheating

Potential engine damage
