The radiator on my Canter is located about 600mm behind the front grille, so airflow is somewhat restricted with this type of setup. To allow the radiator to work at peak efficiency, it must be kept clean. In a vehicle that spends the majority of its life on the tarmac, keeping the radiator clean may not be a challenge, however, if the vehicle is going to be used off road, as mine will be, then protecting the radiator from damage, mud or debris becomes quite important.
Also, on my truck an intercooler is mounted directly in front of the radiator. Airflow restrictions, like a build-up of dust on the front of the intercooler can be relatively easy to remove, but if anything gets stuck between the back of the intercooler and the front of the radiator it would affect both the efficiency and cooling of the engine, not to mention that it would be extremely difficult to clean.
At this point I should also add that cleaning a dirty radiator or intercooler must be done with extreme care.
Never use a pressure washer to clean a radiator/intercooler, as these devices have the potential to cause a lot of damage very quickly.
The radiator/intercooler fins are very easily bent/damaged and if this happens their cooling capacity will be seriously affected.
Adding a splash guard under my radiator and intercooler has always been on the “to do list”, but I never got around to it; until now…
This was a very simple modification and took a minimal amount of time and effort to implement. Given the increased airflow to the radiator and the added protection a splash guard offers, I would definitely recommend a similar modification to other Fuso Canter owners.
