i installed one on my 345 International truck. I had the van body off chassis only and I was driving to Miami on I-95 in beautiful weather, dry as a bone at around 2:00pm. Oddly I noticed in my mirrors my rear tires were shiny like they were wet.
That made no sense, so I promptly made a side of the road safety stop.
A SS flex blade had broken and severed the rad hose, losing all the coolant. Lucky the engine never got hot, and I wasn't standing by looking at the engine running while parked when the blade failed.
Not sure whatever benefit they might have, they are NOT worth the risks. If your neck was struck, it would be lights out forever.
