    Well? I press the R button for the Raditor but I really don't see any different changes. Just on the side of the screen , It just changes to Radiator 2 , 4 , 6. Open and close and etc.

    I'm not an expert at all...but it's a good question.

    It's a device to help the engine to cool itself, some guys here will explain it better than me and in better english. Without radiator or cooling system the engine would reach a dangerous temperature and even seize or explode.

    The more it is open the more it allows cold outside air to cool the engine. The number help to know how wide you open it: the widest setting is better for cooling but causes drag and thus performance loss.

    here are some pics i found:

    this is how a me 410 radiator looks from the rear:


    this is the Spitfire radiator:

    on some a/c when you open the radiator it opens cowl flaps around the engine compartment (usually with radial engines)...and with others like in-line or V engines it opens a flap or flaps behind the radiator box to allow more airflow to cool the engine via the coolant liquid which flows to and from the radiator

    if you look at external views you can see the flaps opening/closing


    What....don't you own a car...or are you too young?

    Do you have complex engine management on?

    The problem with normal cars is that all the engine structural parts are well hidden under the cowling: one have to look directly at the engine to ask the question "hey, strange, what is this".

    The aircraft (WW2 in-line engine) are generaly less compact and the different engine parts (intercooler radiators can better be seen they are more striking)...
    The way the Fw190A radial engine is built seems more logical and more compact to me (with its annular radiator direcly in front of the engine) than any other WW2 aircraft (with the Seafury being a notable exception), and this is why i find this bird so pure and beautiful! It looks certainly more structurally perfect than many other AC, imho that is.

    Opening/closing the Radiator has four effects depending on the aircraft.

    1. (The obvious one) open radiator cools the engine better.

    2. (Fairly obvious) most but not all aircraft lose a touch off top speed with radiator open. P51 is exception.

    3. (less obvious but easily proven) many aircraft, the Lagg being a classic example, handle like crap at low speed with the radiator open.

    4. (controversial and hard to prove/disprove) Some people claim the damage model in the game simulates radiator cowl open making the engine more vulnerable to damage from hits. According to this theory closing the radiator in game protects the engine.

    That`s about it.

    Tuskegee1989, maybe you have complex engine management off? Because it`s pretty easy to see the advantage of radiater open when your engine starts overheating.

    I think this is only true for the Il-2 armored radiator grids.

    The FW-190 has a radial engine and is air cooled.It has no liquid coolant. The air just enter through the cowling (in the 190 case helped by a fan), passes between the cylinders, cools them down and exits through the exit slots on the side of the fuselage, just behind the engine.
    The annular radiator you are talking about is the oil cooler in the 190A. The 190D has anular radiator for coolant.
