Product Description

2001, 2002, 2003, 2004, and 2005 BMW 530i cars may use this thermostat assembly from Wahler. The thermostat is a component of the cooling system. When the engine reaches a specified temperature, the thermostat lets coolant into the radiator. This thermostat assembly includes the gasket for sealing it, and it has the housing to protect it. For the thermostat to protect the engine from overheating, it must be intact and operational. A damaged thermostat may cause the engine's heat to build up without an outlet, damaging some portions of the engine. This thermostat assembly is recommended for use on BMW 530i vehicles from 2001, 2002, 2003, 2004, and 2005. This thermostat assembly may not be compatible with the cooling system on other makes, models, or years of vehicle.


  • Strict quality control, and functional testing
  • Self-cleaning and self-aligning thermostat valve
  • Original equipment design provides exact fit and performance
  • Precise sealing edges reduce leakage and premature cooling
  • Temperature sensitive heat motor provides consistent valve response for smooth performance and precise engine cooling
  • Stainless steel assembly and springs are engineered for long life

The prices were good and the website was easy to navigate. When I received my shipment, it was incomplete due to one part being stock-ordered. However, when I called PartsGeek's customer service line, I was treated politely and my questions about my order were answered. My first experience ordering through PartsGeek was a good one. I intend to purchase more parts through them in the future.
