Disadvantages of the D5252T engine
This diesel engine is quite clever, featuring direct injection and a dependable Bosch VE37 high-pressure fuel pump;
Since the cylinder head is extremely concerned about overheating, it is crucial to keep an eye on the cooling system;
The timing belt needs to be replaced once every 120,000 kilometers, and if it breaks, the valves will bend;
Although the boost control valve frequently fails, the turbine operates well here;
The mass air flow sensor and vacuum pump are the engine’s weak points.
