Facet 7.8434 Engine Coolant Thermostat with Gasket

The Facet 7.8434 is a precision-engineered engine coolant thermostat designed to maintain optimal engine operating temperature by controlling coolant flow through the radiator. This OE-equivalent thermostat ensures proper thermal management for improved engine performance, reduced emissions, and enhanced fuel efficiency.

Key Features:

• Includes gasket for complete installation
• Mechanical wax pellet actuation for reliable temperature control
• Precision-calibrated opening temperature for optimal engine performance
• Made in Italy with high-quality materials for durability
• Direct OE replacement design for easy installation
• Reduces engine warm-up time and maintains consistent operating temperature

Facet thermostats feature carefully selected materials engineered to resist common failure modes. The wax-filled sensing element expands at the calibrated temperature to open the valve, allowing coolant circulation to the radiator. When engine temperature drops, the thermostat closes to maintain optimal operating conditions. Proper thermostat function is essential for engine longevity, performance, and emissions control.
