Coolant mixing with engine oil caused severe internal damage, leaving this DONGFENG cement truck diesel engine completely seized. In this video, we tear down the engine, expose the real damage, and perform a full heavy-duty diesel engine rebuild from scratch.
You’ll see the real workshop process including:
• Diagnosing coolant contamination in engine oil
• Opening a seized diesel engine
• Crankshaft, bearing, piston & cylinder inspection
• Head gasket failure and overheating damage
• Deep cleaning and precision rebuilding
• Step-by-step professional reassembly
• Engine restored back to life
This is real mechanical work, real tools, real skills — no fake content.
Perfect for mechanics, truck drivers, engineers, diesel lovers, workshop owners, and restoration fans who enjoy authentic engine rebuilding videos.
