Electric cooling fans reliability

[JeepSJ]

I have read where the newer DMax trucks (and many of the gasses) are now coming with electric cooling fans. For those of you who tow, have the electric fans been able to keep up with the cooling tasks?

They are not electric. They are visco-electric. This allows the ECM to activate the clutch when needed. There may be some benefit to this on older models, but you would have to build a control of some sort assuming it would fit.

Reliability has been decent from what I have seen. I saw one that went bad, but that is about it.

Ahh, maybe it is just the gassers that are full electric. We have had the debate for so long on whether electric fans could keep up with demand, I was hoping that the factory had come up with something.

Electric cooling fans draw a lot of juice if they are anywhere near the CFM rating of an engine-driven fan. An electrically operated fan-clutch makes more sense, and it avoids the sometimes inconsistent calibration of a viscous fan-clutch.
