Restoration of the exhaust gas recirculation (EGR) system and its cooler is a complex of works aimed at restoring the effective operation of the system, which reduces harmful gas emissions and controls the temperature of exhaust gases before their re-introduction into the engine. Clogging or malfunction of the EGR valve and cooler leads to unstable engine operation, increased smoke, electronic system errors, and excessive fuel consumption.

During restoration, the EGR valve is cleaned and checked, the cooler is flushed or repaired, and the system is tested for tightness and proper operation. This allows for an optimal combustion mode, normalizes engine operation, and maintains the vehicle’s environmental standards.
