Hybrid battery fan maintenance

After upgrading all the bus bars and nuts today on my battery pack, I decided to take a look at the fan and clean it if needed.

Couldnt find my can of compressed air so used a toothbrush.

 

Also besides the filter I already added some time ago on the outside of the vent.

I found out about another one and wanted to see if I could add it, it was also said that it is not found in all models so I wasnt to surprised mine didnt have it.

Some sites will say it fits 2010-2015 but it did not really fit my 2010 but I made it work.

Now the fan is clean and has two filters to help keep it clean.
