Delica Canada | Mitsubishi Van Club

Wonder if some one might know what is making this noise. Upon acceleration, say up a hill, the L400 will kick down a gear and a loud, high pitched fan/air noise comes on. seems to be coming from mid dash engine compartment. Letting up on the gas pedal shuts off problem.. No notice or change in engin...

wonder if anyone can tell me what the dash light that looks like the rear of delica with curved skid marks behind it are?

thanks
