I was installing a BOV on my evo then one of my little screwdriver fell in the space between the Fan Housing and the Radiator, I had to get a metal hanger to fish it out. I bent a lot of the metal mesh thing on the radiator on the process. My question , Is there a possibility that I put a hole on the radiator? should I be concern about the bent mesh things on the radiator? Will it affect cooling? thanks in advance for your help

 

You will probably know if there is a leak because you will see it or smell it, bending up the mesh wont make your radiator leak and probably wont hurt anything.

 

If there was a hole, How bad will it leak? It will be under pressure right? so will the coolang spray or just leak slowly?
