convert viscous belt fan to electric fan

[rion]

just wondering if any tsikoteers have experienced converting belt-driven clutch fan to electric fan.

did it gain additional power? and did the engine run cooler?

and also, has anyone put an electric pusher fan in front of their radiator and yet still left the standard viscous fan in place?

you will gain power because there is less load on the engine. but the clutch fan can theoretically cool better because it speeds up as the rpm goes up.

i've put a push fan on my car but that was just to aid in a/c cooling which suffered after the intercooler went in.

in inspection sa surplusan, pano po mo malalaman kung fan ay mount front or back ng radiator? pag pinatakbo ba?

diba pag electric na yung fan, mas constant na ang rpm nun than sa clutch fan na connected sa engine?

depends on the blades rotation

right , pero mas malakas parin ang clutch fan

I notice that our belt driven fans has limit speed. nag freewheeling nalang siya...

I have no plans right now, but just wondering how do you remove it? it's not as easy as removing the fan right? I mean removing the blades will still consume power unless you have to do something about the belt and other connections right?

removing the blades would have practically elimated the fan as a load on the engine

for an electric driven fan, you might need to install a thermostat switch so that the motor will not have to run continuously, otherwise it would not last long and the carbon brushes of the motor would need replacement regulary as well as its bearings

in some cars, the fan motor is not powered at all when the car is at some speed where wind speed is enough to cool the radiator and the thermostat stays at "off" state

That's normal if the engine is cold. Try running the engine to its operating temperature, then shut it down. The fan shouldn't be "free-wheeling" at this point if your viscous coupling is still intact.

It should be. You can't reroute the belts and leave out the fan gear since that one's also connected to the water pump.
