• OE-style housing construction based on vehicle-specific requirements
• Rein CTA0014 for application-specific cooling system service

Detailed Description

Rein CTA0014 thermostat housing assembly is manufactured as an OE-style replacement for vehicles that require a precise cooling system component. The housing is produced from vehicle-specific molds to help maintain factory dimensions and proper sealing surfaces, while the thermostat is temperature calibrated for consistent response at the specified operating point. This makes it a practical choice for Audi and Volkswagen cooling system repairs where fit, material selection, and temperature control matter.

This part cross-references 06F121111F for the same application. Rein CTA0014 is a direct replacement option for drivers and technicians servicing 2006-2008 Audi A3, 2006-2008 Audi A3 Quattro, 2008-2009 Audi TT, 2007-2009 Volkswagen Eos, 2006-2008 Volkswagen GTI, 2006-2008 Volkswagen Jetta, and 2006-2008 Volkswagen Passat applications.

What It Helps Address

• Coolant temperature regulation concerns
• Thermostat housing leaks at the cooling system interface
• Improper thermostat opening or closing behavior
• Fitment issues caused by worn or damaged OE housing components
• Cooling system service on Audi TT, Audi A3, and Volkswagen models

Installation Notes and Tips

Verify the OE part number and vehicle application before installation. Inspect mating surfaces, coolant passages, and adjacent hoses for wear or contamination during service. Because this is an application-specific assembly, confirm the housing style and thermostat specification match the original component on the vehicle. For best results, follow the factory service procedure and refill the cooling system with the correct coolant after installation.

Quality Assurance

Rein designs its thermostat assemblies to meet or exceed OE material requirements and to follow factory tolerances for fit and function. The housing construction and calibrated thermostat are selected to support consistent cooling system performance in the specified applications. Rein CTA0014 is built for OE-style service on 2006-2009 Audi and Volkswagen platforms.
