The weight of the MHA engine according to the catalog is 110 kg. The Ford MHA engine number is located at the front, where it meets the gearbox. This engine does not tolerate poor fuel, quickly damaging the spark plugs and then the coils. Owners often have to clean the throttle and idle air control valve. The fuel filter mesh in the tank also frequently gets clogged and the fuel pump fails. Sometimes, the timing belt and its tensioner pulley do not last until the recommended 120,000 km service interval. Due to the absence of hydraulic compensators, the valves need to be adjusted every 100,000 km.
