- Check if the radiator is clogged with dirt. If necessary, clean the radiator as follows:
Attention:
- Do not bend or damage the radiator fins.
- When cleaning the radiator without removing it from the vehicle, remove all adjacent parts, e.g., radiator cooling fan assembly and horns. To prevent water from entering, wrap electrical wiring and connectors with protective tape.
1. Water the back of the radiator core with water from a hose vertically downwards.
2. Again, pour water over the entire surface of the radiator core once every minute.
3. Stop watering if dirty water no longer flows from the radiator.
4. Blow air through the radiator core from the reverse side vertically downwards.
- Supply compressed air at a pressure below 490 kPa (5 kg/cm²) and from a distance of more than 30 cm.
5. Blow air again over the entire surface of the radiator core once every minute until no more water flows.
