If the coolant level drops there, it is too late. The pump will cavitate very very soon. (assuming is the stock pump). I would install it in the expansion tank or overflow tank. When the coolant drops there you will have more of a chance to head back before the pump gets exposed.

Hi Rusty, I don’t think coolant level switch should be on your water = pump. If the coolant level drops there, it is too late. The pump will cavita= te very very soon. (assuming is the stock pump). I would install it in the e= xpansion tank or overflow tank. When the coolant drops there you will have m= ore of a chance to head back before the pump gets exposed.
