Engine Overview and Common Failures

The weight of the YD25DDTi engine according to the catalog is 200 kg. The engine number YD25DDTi is located on the cylinder block. Owners most often encounter typical fuel system malfunctions. The reliability of injectors and fuel injection pump is decent, but the cost of repair is very high. The engine is prone to overheating and rarely cracks the cylinder head under heavy load. Without a turbo timer, the life expectancy of the turbocharger is reduced to 100-150 thousand km of mileage. The vacuum control system for turbocharging often breaks down, and the repair is expensive. The EGR valve quickly gets clogged with carbon deposits and requires regular cleaning. Usually, at a mileage of 200-250 thousand km, the timing chain mechanism needs to be replaced.
