This 2020 Dodge Durango overheating issue arrived on a tow truck. We are performing diagnostics to isolate the cause.
The vehicle arrived with a 3.6 engine that is running hot. We start with a visual inspection and fluid analysis to see what we are dealing with. This is a standard look at how we approach a cooling system failure before tearing into the major components.
Proper automotive diagnostics are the only way to avoid guessing. By checking the dirty fluid and running through the system, we identify the root cause of the Dodge Durango overheating problem. This process is essential for anyone doing their own engine maintenance or just wanting to know what happens inside a shop during a professional car repair.
