170° PERFORMANCE THERMOSTATS for FORD Modular V8/V10 & Duratec/EcoBoost V6
Home 170° Thermostats Application Guide Why A Low Temp Thermostat? 170° vs 180° or 160° 4.6L DOHC Refill/Burp Procedure Where To Buy Contact Us & About Us
Many have searched the internet and part stores for a properly fitting low temp thermostat for their late model GT500, Cobra, Mach 1, Bullitt, Mustang GT and Boss 302. Beware of aftermarket companies who sell the same thermostat for all Ford modular engines. Those units are designed for the 2V SOHC engine 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.

Our FORD-4D (right), FORD-G5 & FORD-50 thermostats are custom made with the same size diaphragm and bypass control as the OEM units. Each of our thermostats is modified by hand using only U.S. made parts and then quality inspected to ensure consistent opening temps. These t-stats are the only ones specifically designed to fit these applications making them the best performing low temp units on the market!
