Almost a year since the last post

Here we go.

Some time ago I removed the front AC fan as I believe it is reducing the airflow to the radiators.

The fan I bought to replace the mechanical fan is a SPAL - VA18-AP71/LL-59A.
The item number is -> # 30102049 . 2070 CFM 16" Spal Curved Blade Puller Fan

The unit is 2440g which means it's 700g heavier than the mechanical fan which is 1710g.
But, it reduces the parasitic losses and you can get to remove the AC fan which is a very heavy unit.









Mounting it was as easy as drilling 4 holes in the radiator, using 4 brackets and bolting it.

The clearance to the engine is simply perfect - like if it was made for the CSL.
I also cut the OEM fan shroud and put it back on.
The installations looks very clean.

I am driving this fan using the control unit of the AC fan and it works perfect.
