NAVISTAR SPEC
WHY 203° IS BETTER THAN 195°
Diesels Run Most Efficiently At Approximately 200° Or Above. A Factory Equipped 195° Thermostat Will Maintain An Operating Temperature At Approximately 165°-170°. The Powerstroke Has Such An Efficient Cooling System, That This Low Flow When The Thermostat Is Slightly Open Is Normally Enough To Keep The Engine Cool. The Downfall To This Is That The Engine -- When Our Trucks Are Not Under Load -- Never Begins To Reach Its Optimal Operating Temperature. This 203° Thermostat Maintains A Minimum Operating Temperature Of 190°. This Brings The Operating Temps Up From As Low As 170° To As High As 203° Depending On The Operating Conditions Of The Truck. This Is Closer To The Operating Temperature Range That Is Preferable In Our Trucks For Optimal Efficiency.
