On my first 240sx I took off from a stop light, soon as the revs hit 3k and I was ready to shift into 2nd, the radiator clutch fan came flying off underneath the engine bay. It was night time so I couldn't see anything. Car wouldn't start so I had to tow it home. Turns out the fan disconnected the distributor wire and messed up a couple other things... Pretty much from that day forward I vowed to only install electric fans on my car. 4 years later electric fans have done me well.
