Thermostats & Housings

Thermostats in Powerstroke engines regulate coolant flow to maintain optimal operating temperature. They open and close precisely based on temperature thresholds. Housings secure thermostats and connect coolant passages. Made from durable materials, they resist heat and corrosion. Proper thermostat function prevents overheating and ensures efficient engine warming. Reliable housings provide leak-free sealing under pressure and thermal stress.
