General Punto GT injector cooling fan

[TheAutopsy]

Hi guys, I was doing some work on my GT changing the water pipes that are rotten, and I removed the battery tray to get more room to work.
Then I found, what I discovered online to be, the injectors cooling fan. I did not knew that there was such a thing.
And I have some questions.
Can I test the fan motor to see if it works? If so how do I do it
Does it do a big difference in cooling the injectors? because the other end that goes to the head was disconected.
So I am wondering If I should leave it there or take it out if it doesn't work.

Its more so for the hotter climates, its controlled by a little sensor which sits near the injectors, take the multiplug off it and bridge the pins with ignition on this should make it run
