The weight of the EZ30R engine according to the catalog is 170 kg. The EZ30R engine number is located at the junction of the block and the gearbox. This engine is known for its high fuel consumption and tendency to oil leaks. The cooling system is not renowned for its reliability, and the engine is prone to overheating. Due to cheap lubrication, the timing chain tensioner may seize, requiring a replacement of the timing belt kit. Typically, after 150-200 thousand km mileage, progressive oil consumption begins. However, the main problem with these engines is the limited availability of quality service.
