The intercooler is air to air type and has a large cooling fan capacity. The intercooler life and performance
depends on the intake air condition greatly. Fouled air pollutes and clogs the air fins of intercooler. As a

whether the intake air systems like air filter element are worn or polluted.
- Cleaning of intercooler fins: Every 500 hours at Normal site condition.
