Hi I have a 1992 Volvo A25 rock truck,been leaking some oils drips that the hydraulic radiator fan pulls towards it.Pressure washed it ,think it may be this valve to do with cooling maybe,not certain.Not even sure what this valve is.I have the online manuals for the truck,but still cant locate it in there.Anyone have the answer as to what this piece is ?Seems like engine oil blowing around.This valve though seemed to be closest and wettest.
