I have a 1987 firebird and there is an air hose comming out from under battery tray and it seems to be attached to a fan motor under the tray it comes up inside the pass side inner finder and curves out towards engine does this connect to anything on motor? it has come on when i was driving one day i noticed it when i stoped car and got out opened hood and it was blowing air through the tube.
thanks

No the only fan that comes on when a/c running is eng cooling fan on radiator it has only come on once when i was test driving the car after i purchased it.the hose is only 1 1/2 inch in diameter.

maybe it's someones idea of a supercharger?

Does it look OEM?

Perhaps some emissions device? If it's to do with emmisions, there should be a decal on the rad support, or there was. Couple things to consider, but just guesses.

is the tube over by the exhaust manifolds or by the alternator cause a buddy on the fiero fourm told me there air tubes to keep the outer casing of the alternator cool so it doesnt overheat the regulator inside the alternator.

That is interesting,I'll look into that.The tube comes up from under battery tray and runs along inside fender, then curves just at the shock tower and stops.Looks like it should hook to something.
