Questions regarding the FM of the Fw-190 A-8/9

Do you mean that being able to change the radiator flap in game is wrong? Or is the radiator flap in game is for other stuff than cooling the oil?

The cooling flaps on the FW190 were used to manage the cylinder head temperatures, particularly the lower rear bank of cylinders, as these had a propensity to overheat badly in the prototype and early models.

The oil cooling system was more complicated. The oil cooler was a ring around the inside of the engine cowl opening, protected by a ring of armor plate on the outside of the opening (that separate ring you see on the cowl opening). The propeller assembly fan blades were primarily designed to function as part of the oil cooling system, with an added - and much needed - benefit of aiding the cooling of the cylinder heads as well.

In addition to what Treetop said, the oil cooling could be adjusted by changing the width of a gap in the oil cooling ring. This could only be done by the ground crew. The wider the gap, the better the cooling, but the slower the plane. A wide gap for instance for desert conditions cost about 20 km/h.
