The weight of the N7Q engine according to the catalog is 143 kg. The engine number N7Q is located at the back, at the junction of the block with the cylinder head. Owners of Renault vehicles with this engine are often concerned about oil leaks from the oil separator. Due to a clogged crankcase ventilation, significant oil consumption often occurs. The timing belt does not always last the recommended 90,000 km, and its failure can cause valve damage. This power unit is prone to overheating, and the gasket tends to wear out quickly. Weak points also include engine mounts, thermostat, water pump, and fuel pump.
