ABSTRACT:
An improvement in devices for the thermostatic control of engine coolent comprises a radiator hose with an internally mounted thermostatic valve. In one embodiment of the improved device, a flexible hose has a radially inwardly projecting annular flange on which the radially outwardly projecting annular flange of a conventional thermostatic valve may seat. In another embodiment, the annular flange of a thermostatic valve is modified to permit it to be clamped onto a coil of a helical spring held coaxially within a flexible radiator hose. The improved thermostatic coolant control devices eliminate the requirement for gaskets, gasket cement, and unbolting and bolting metal parts together heretofore required of the replacement of thermostats.
