BF-109K4 and BF-109K4(C3) Incorrect cooling

[OREL_Erichos]

I will try to test it.

Hi Pilli,

I tested Bf-109K4, 1944, Normandy map. All is working correctly. I climbed with MW50 and with radiator auto - radiator was opening and closing due to temperature, then I did it without MW50 - again radiator was working correctly.
Are you sure that you use MW50 correctly? I can send you my track file if you want.

Salute

Dear Friend
Look at the water temperature indicator (upper). The lower one is the oil temperature. When the engine is overheated, the radiator flaps in automatic mode are not open as much as possible. you can check: heating the engine in auto mode of hunting, then in manual mode open the radiator. and you will see that the radiator flaps are still open.
Problem is that the radiator in auto mode, with overheating, is not fully opened. I think that it works on the temperature of the oil, and not on the water temperature. but should open when the coolant is overheated!

This is incorrect.

They are both oil temperature gauges. The lower gauge indicates the oil temperature after leaving the oil cooler and entering the engine. The upper gauge indicates the oil temperature after leaving the engine, going to the oil cooler. Besides, the tick mark numerical values would be much higher if the gauge were indicating coolant temperatures.

As far as I can tell, there is no glycol temperature indicator in the bf-109K4 cockpit. Maybe this is accurate historically, or maybe this is another of the the old legacy inconsistencies with cockpit gauges (i.e. the F6F Hellcat, equipped with an air-cooled radial engine, having a "coolant" gauge for engine temperature)

At any rate, the radiator flaps behave normally and as expected per demands placed on the engine.

I think that when the inscription "Engine overheating" appears, the radiator in auto mode should be maximally open! so it occurs on all Bf 109, except Bf 109 with MW50.
And this is not correct!

Anyone who has played this game over the past fifteen years knows that the activation of the OVERHEAT! message is too conservative and comes on too soon. It is largely ignored by the community. Ignored by those who know the cockpit gauges and uses them instead of the HUD log, anyway.

The flaps are fine, dude. Understand it.

try to think logically: if there is overheating, then the radiator should be opened by 100%. This is logical and not subject to discussion, but this does not happen on BF 109 only with MW50

Hello! Check on the Balaton's summer map.

Greetings colleagues !!!
Wiped dust from the joystick and remembered my youth))
I see that the radiator shutters on the BF-109 with MW50 have not been fixed?
