Viscous Fan vs Electric Fan
Being as obsessed with my cooling system as I've been with my lights I've decided to entertain the thought of installing an electric cooling fan and getting rid of the viscous fan. I parked my car outside all day on a 110* day then I went and sat in it and turned the a/c on with the dual fans on high. I sat idle in the same spot for about 30 mins and there was zero cooling. This has come in the wake of another forum member having issues with his a/c cooling down his car. So after the 30 mins I put my foot on the gas and got the RPMs up to 2500 and I then noticed that there was some cool air coming in through the vents. Regardless of the clutch locking up or not, the fan only spins as fast as the engine and nothing more. My fan clutch is new, radiator is new, and my fan/fan clutch is even from a 300E and it works amazing when I'm driving, even if its only 15-20 mph, but at a stand still the fan is useless. What I plan on doing is either buying a retrofit electric fan if anyone has any info on this, or I will build my own. Anyone care to add or comment on this with any suggestions or advice? Thanks.
