The weight of the 4G15T engine is 145 kg (with attachments). The engine number 4G15T is located at the front, at the junction with the gearbox. For a turbocharged engine, this unit is very reliable and does not cause many problems. The most common complaints are related to the temperamental throttle valve, but cleaning and calibration can help. After 100,000 km, excessive oil consumption often occurs due to wear of the piston rings or valve seals. Keep an eye on the condition of the timing belt, as its failure usually results in bent valves. Weak points include short-lived ignition coils, thermostats, and engine mounts.
