ZEROSTART Series 8000 Circulation Engine Heater

Description

This is a true engine block heater that keeps your engine warm with its own circulation pump.  I purchased it many years ago but never installed it.  From what I can see, the product remains unchanged and can be purchased on Amazon for .00.  I don't think I ever opened the package but I cannot see any instructions folded up inside.  It is possible that there were instructions but I can't say for sure.  Either way, because it is a currently produced product, I'm sure you could obtain instructions from "TEMRO."
