[DeTomaso] 1972 detomaso pantera cooling system

[boyd casey]

To any one interested Vintage Air makes an electronic servo valve that
allows you to "by pass the heater core (and cabin) from inside the car with
a switch. I don't know if it's fail safe enough for race track safety
inspectors but it's pretty cool and it dosent just cut of the water flow it
allows it to "By Pass" the heater core but continue flowing through the rest
of the cooling system so it is not adversely afeected by just cutting off
the normal flow pattern.
