MAHLE TI 256 77D Engine Coolant Thermostat Kit

The MAHLE TI 256 77D is a precision-engineered engine coolant thermostat designed to maintain optimal engine operating temperature for improved performance and efficiency. This OE-quality thermostat opens at 77°C (170°F) to regulate coolant flow between the engine and radiator, ensuring your engine reaches and maintains its ideal operating temperature.

Key Features:

• Opens at 77°C (170°F) for precise temperature control
• OE-quality construction trusted by manufacturers and technicians worldwide
• Wax-element expansion design for reliable, maintenance-free operation
• Helps reduce emissions and fuel consumption while optimizing engine performance
• Improves combustion efficiency and cabin heating effectiveness
• Direct replacement for failed or worn factory thermostat

MAHLE is the world's leading manufacturer of thermostats, supplying OE and aftermarket components for cars, trucks, and commercial vehicles. The thermostat uses a precisely formulated wax pellet that expands when heated to open the valve, allowing coolant to flow to the radiator for cooling. When temperature drops, the wax contracts and a spring closes the valve to maintain optimal engine temperature. Replace your thermostat during cooling system maintenance to prevent overheating or overcooling issues that can damage your engine.
