I got myself and anemometer, just a cheap one off Amazon to do a few tests on airflow through the radiator.

I've got a 16" Bosch fan I had spare off an Audi S4, and it works quite well.

I did a few tests yesterday, and some more scientific ones this morning.

I copied a similar method as another Unimog owner did on a stock mechanical fan and bare radiator.

The results are similar to what I got, and I have an a/c condenser and another fan in front of the radiator.

The airflow varies quite a bit across the radiator as you can see in the results.


I did the all the test with the bonnet up.

I'll figure out the way to fix the anemometer to the radiator and connect it to my laptop, and go for a drive and see how much airflow comes through when I am driving. I might have to resort to using cable ties and strapping it to the grill.
