Greetings,

I'm looking for ways to put a coolant level switch in the engine, and remember that the FD had a level sensor.  I never looked it one of these before, so I'm wondering how it worked.  Does anyone have one they can look at, or perhaps send me if you don't want it?  Does is have some sort of float in it?  I have an extra 1/4" NPT hole in my upper water pump housing, which would make a great place for a switch, but I haven't found one that seems like it would work there very well.  Did the FC use level switches?

Thanks,

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 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.
