 These particles can block the radiator cells and prevent irregular flow of the coolant in the radiator. This can lead to increase in engine temperature.

For external blockage, the most cause of this is both dust and oil. The shape of the fan tends to pull stuffs to the radiator. That is why a radiator gets blocked quickly in a dusty area. If there is any form of diesel and oil leakage in any part of the engine, the fan tends to pull it to the radiator by force. Coupled to the dust, the oil gets stuck on the radiator. This blockage will not allow the effective cooling of the coolant and water by the fan and this will not effectively cool the engine.

Solution

For internal blockage, brings in the use water filter. The job of this water filter is to prevent the entrance of solid particle of any size from entering into the radiator. This water filter will be changed by every servicing time to ensure efficiency.

For external blockage, the service of a radiator steam flushing machine will be brought into use. A soundproofed generator will prolong the blockage time and if not the flushing will be done from time to time depending on the observation done on the radiator.

The coolant sensors will also showing a high level of temperature which will also indicate either a leakage or oil blockage.
