Rein CTA0079 is a practical choice when replacing a worn thermostat housing on BMW 330i and BMW X3 cooling systems, as well as other listed BMW models.

What It Helps Address

• Coolant temperature control that is no longer consistent
• Thermostat housing wear from age and heat cycling
• Seal-related coolant seepage at the housing interface
• Cooling system service needs on OE-style BMW applications

Installation Notes and Tips

Verify the part number CTA0079 against the vehicle’s cooling system configuration before installation.
