The 2nd generation FORD-50 thermostat is made with the same exact
components as your OEM unit, including a rubberized diaphragm. It's a
direct-fit unit with proper bypass control so you're guaranteed maximum
efficiency from your cooling system. No Chinese knock-offs here, this
is the highest quality unit currently available for this application.
This
thermostat will provide the best possible heat dissipation from your
setup and even deliver better overall performance than our competitor's
160° thermostats. We believe the 170° opening temp is the ideal balance
for high performance engines, providing high flow to your radiator by
mid-180 temps while still providing good all season performance. With
proper fan settings your coolant temps in cool weather will be in the
170s and in hot weather the 180s, giving those running high levels of
timing and/or boost added protection against engine-damaging
detonation, as well as, maximum hp.
