NOS Thermal Vacuum Switch-3 port AC Delco 212-26

["Cadillac Kid" Greg Surfas 15364]

I just found a couple of these hiding in the wrong drawer.
NOS TVS for many, many applications.
specs: 3-port, 220*F switching, 1/2" -14 N.P.T.
top port(white) ported vacuum
middle port(black) distributor
bottom port(black) manifold vacuum

this TVS is for the hot idle speed-up feature that was used on 1968 on up through the late 70's. if the coolant temperature reaches ~220*F, manifold vacuum is sent to the distributor vacuum advance to speed up the idle to help cool the motor(higher fan & water pump speed, advanced timing).

$125.00 (OBO) plus the shipping.
