170° PERFORMANCE THERMOSTATS for FORD Modular V8 Engines - 4.6L/5.4L SOHC & DOHC

Many have searched the internet and part stores for a properly-fitting low temp thermostat for their late model GT500, Cobra, Mach 1, Bullitt and 05-06 Mustang GT. Beware of aftermarket companies who sell the same thermostat for all Ford modular engines. Those t-stats are designed for the SOHC and, if installed in the improper housing, will be unable to shut off the bypass allowing hot coolant to recirculate back into the engine at all times, reducing the efficiency of your cooling system. My 4.6L DOHC (right) & 5.4L DOHC thermostats combine the same large diaphragm as the OEM unit with proper bypass valve control. Each of these units is carefully modified by hand using Stant parts and inspected to ensure consistent opening temps. These t-stats are the only ones specifically designed to precisely fit these applications making them the best performing low temp units on the market!

Whether you are using an aftermarket radiator or not these thermostats will provide the best possible coolant temps and heat dissipation from your setup along with reduced warm up times and better cold weather performance when compared to a t-stat with holes drilled in the diaphragm. I 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 maintaining a decent level of all season performance.  With proper fan settings your cruising 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 predetonation as well as maximum power output.
