Rein 955-106-126-01 Engine Coolant Thermostat C F - 80 176

The Rein 955-106-126-01 is a precision-engineered engine coolant thermostat designed to regulate coolant flow and maintain optimal engine operating temperature. This thermostat opens at 80 degrees Celsius (176 degrees Fahrenheit), making it ideal for performance applications or warmer climates where a lower temperature threshold is desired.

Key Features:

• 80°C (176°F) opening temperature for improved cooling performance
• Precision-calibrated wax pellet element ensures accurate temperature control
• High-quality construction meets or exceeds OEM specifications
• Direct-fit replacement for specific European vehicle applications
• Helps prevent engine overheating and maintains consistent operating temperature

Rein Automotive is known for manufacturing quality replacement parts for European vehicles, with a focus on German automotive applications. This thermostat is engineered to provide reliable performance and proper coolant system operation. The 80-degree Celsius opening temperature is lower than standard thermostats, which typically open at 87-92°C, allowing coolant to circulate earlier and potentially reducing engine operating temperatures during high-performance driving or hot weather conditions.

Proper thermostat function is critical for engine longevity, fuel efficiency, and heating system performance. A faulty thermostat can cause overheating, poor heater output, or increased emissions.
