Cheap models of Daewoo and Chevrolet are often equipped with unreliable radiators, which usually start leaking already at 50,000 km, and this cylinder head cannot withstand serious overheating. Timing belt breakage. This engine is prone to oil leaks, and often it seeps from under the valve cover and gets directly on the timing belt, and when it breaks, in most cases it bends the valves. Auxiliary equipment. Unreliable auxiliary equipment causes a lot of problems for owners, and most often the starter fails, the thermostat sticks, and the water pump leaks. Other drawbacks. Hydraulic compensators here do not tolerate cheap oil and can start knocking even before 50,000 km, the engine wiring harness often wears out, and the sensors are not reliable. With high mileage, excessive oil consumption often occurs due to worn oil seals.
