Customer Complaint – 2015 Dodge Durango Overheating and Coolant Leak

The owner of this Dodge Durango contacted us after noticing coolant leaking underneath the SUV along with occasional overheating symptoms during traffic and longer drives.

The customer reported:

• Coolant leaking under the vehicle

• Engine temperature fluctuating higher than normal

• Sweet coolant smell from the engine bay

• Low coolant warning

• Cooling fan running more frequently

After performing a full cooling system inspection on-site in Hermitage, we found the radiator had developed a leak and could no longer maintain proper cooling system pressure.

To prevent further overheating and potential engine damage, the radiator assembly needed replacement.

Common Cooling System Problems on Dodge Durango 3.6L V6 Models

The 3.6L Pentastar engine used in many Dodge Durango models is generally reliable, but cooling system components can wear out over time due to age, heat cycles, and mileage.

Some common cooling system issues we frequently see on Dodge Durango vehicles include:

• Radiator leaks

• Thermostat failure

• Water pump leaks

• Coolant hose deterioration

• Coolant reservoir cracks

On this particular 2015 Dodge Durango Limited, the radiator had developed leakage near the core area, causing coolant loss and inconsistent engine temperatures.

Ignoring cooling system problems can eventually lead to:
