Well Genbilstein, the persuasive aspects of switching to electric fan are manyfold!
As PanzerSD succinctly and adequately described the disadvantages of viscous or fixed belt driven fans as “Parasitic drag” that is the robber baron of HP.
Over cooling of belt driven fans is one of many disadvantages, while on the plus side of electric ones are:, improved economy (it pays for initial disbursement many times over), more performance as it frees up to 4-8% of engine power and up to 8.5% fuel savings, less noise, environment friendly, and other pluses such as less damage to catalytic converters. A look at
KENLOWE FANS website is worth it!
Particularly their
FAN DESIGN
Alternatively, you might wish to consider a
SPAL FAN of similar design.
If you decide to switch to electric fan I suggest a look at this thread concerning the
Negatively Closed Thermostat, MB part number: 000589746300 (they are difficult to obtain but you can convert a standard one into a negatively closed one by unhooking the “V” bracket from the top plate). which I had to install when I switched to electric fan and my engine runs cool as a cucumber (80-90C) and the fan seldom comes in unless I am stuck in traffic.
