Engine Overview and Common Failures

The weight of the LY7 engine in the catalog is 185 kg. The LY7 engine number is located at the junction of the block and the gearbox. The main problem with this power unit is considered to be the low lifespan of the timing chains. They can stretch up to 100,000 km and their replacement is quite difficult and expensive. When replacing the chains, it is easy to damage the front cover, which is quite costly. Engines of this series are very prone to overheating, and unfortunately, radiators regularly leak. The weak points also include the short-lived pump and the temperamental control unit.
