Product Description and Specifications

The TA2858 thermostat housing assembly is engineered with a combination of plastic, stainless steel, and copper to balance durability and thermal conductivity. Its black finish helps resist corrosion in the engine bay environment. The 0.33-inch inside diameter supports proper coolant flow, while the included gasket or seal ensures a tight, leak-free connection. Two mounting holes provide secure attachment points, and the six outlet ports allow for efficient coolant distribution. Additionally, the bleeder hole facilitates air removal from the cooling system, helping maintain consistent engine temperature. The thermostat is calibrated to open at 180 degrees Fahrenheit, aligning with the cooling requirements of compatible Ford Five Hundred, Mercury Montego, and Freestyle models.
