Followup Powertech 15kw cooling fan

[Gregory OConnor]

Pete, did you see the pic of the genset fan bay on one of the ebay
pt93's? there is something mounted on the fan???? I wonder if it is a
remote start compasitor, or rpm, cfm, gauge??????

on my 94 there is a deflector under the radiator towards the middle
of the bus that directs 30% of the air blowing down through the
radiator towards the street. I believe that 30% takes the other 70%
past the bay door and keeps dust from blowing back up into the fan
intake. I noticed several units have the deflector removed????
