i have been interested for some time in converting to an electric fan. ever since i replaced vfc with a *brand new one,* i have been dissatisfied with it. the engine ran hotter from day one, and several weeks ago it just quit work altogether. i took off the bimetallic strip and adjusted it a bunch of times and have yet not been able to get it to work properly all the time. the viscous fluid is fine because the fan will engage at full strength, its just a matter of getting it to activate proper and at the right time. right now, it comes on erratically on the highway, and around town the engine gets up to 100C or more before it engages and even then it will not disengage right. it will stay on so long that the thermostat will actually close up and the engine will get hot again and when you stop the coolant temp shots up past 100C!! so frustrating.

i dont know if i should try another vfc, thinking that this one was defective, or just get an electric fan and call it a day.

i am wondering why people are so against electric fans? all mbs are now cooled by electric fans. i have heard from manufacturer sources (not mb)that electric fans require less energy and are more fuel efficient and more reliable than vfc systems. what is all the fuss then??
