After my clutch fan flew apart on my old 240 (KA24DE) late at night driving home from work, and left me stranded, I vowed from that day forward I would never return to the clutch fan. Bought Altima fans and wired them up to ignition on and I've yet to have a cooling problem. I have 75% distilled water, 20% coolant and like 5% water wetter lol.
ps. I wouldn't run your fans always on unless its a summer car like mine. Whenever the temp dips below 50F, in the garage it stays
