The weight of the KL-ZE engine is 176 kg (including accessories). The engine number is located at the junction of the block and the cylinder head. Engines of this series are considered quite reliable, but the spare parts are a bit expensive. Please keep an eye on the cooling system, as the aluminum engine block is very sensitive to overheating. On mileage over 100,000 km, oil often leaks from under the valve covers. The timing belt usually has a lifespan of about 80,000 km, but if it breaks, the valves usually do not bend. Hydrocompensators do not tolerate cheap lubrication and may start making noise even before reaching 50,000 km.
