8.3.6. Intercooler
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 result of this, the engine output is decreased and engine malfunction
is occurred. So you always check whether the intake air systems like air filter element are
worn or polluted.
- Cleaning of intercooler fins: Every 600 hours.
