I am fixing my rx330 to be towed four wheel down with my motorhome.
I need to know what the white plastic box(tank) (which looks like a coolant overflow tank) which is located under the battery, is there for. It is connected only to the intake air pipe(lower) and it seams just to be a collector for water in case some water gets into the air filter box. But there are no drain holes for it if it should collect water..
I would like to remove it and place the tranmission oil pump in its place. This oil pump is part of a kit that allows four wheel down towing behind your rv.
Can anyone give me a reason that I should NOT remove this plastic tank?
