Engine EW10J4 commonly faces issues such as timing belt wear, coolant leaks, and EGR valve clogging. For diagnosis, regularly check for unusual noises from the timing belt area and inspect coolant levels to detect leaks early. Preventive maintenance includes replacing the timing belt every 60,000-100,000 km and flushing the cooling system periodically.
