Hi Guys,
I have observed that the car runs smooth when the engine temperature is arounf 85 C.
Normally, fully warmed engine is at 89-90C without AC and 92-93 C with AC.
So to get the engine temps lowered, I thought of changing the VC fan from BMW M51 to BMW M57 .M57 fan diameter is 420mm which is about 40 mm larger than M51 fan and also it has the fan blades joined at the circumference, to reduce noise.
Having purchased a new VC coupling & a M57 fan (Febi), today put them together and.....
The VC coupling holes are not aligning with fan hub holes.
Now can anyone suggest a way to get this thing installed?
Don't worry about the cowling, I'm going to get it enlarged to match the fan.
