Detailed Description

Motorad Standard 288-180 is an OE-style engine coolant thermostat engineered for precise temperature regulation in BMW cooling systems. The copper case and wax compound react quickly to coolant temperature changes, helping the thermostat open and close at the specified 180 degree F range. This makes it a practical choice for BMW 850Ci, BMW 840Ci, BMW 530i, BMW 540i, BMW 740i, BMW 740iL, BMW 850CSi, BMW 750iL, and BMW 850i models that require this temperature specification.

This part cross-references 180-882 and 28880 for the same application. Motorad 288-180 is built to match OEM dimensions and includes the seal needed for service replacement.

What It Helps Address

  • Engine running hotter than normal
  • Slow coolant warm-up or unstable operating temperature
  • Thermostat sticking open or closed
  • Coolant flow control issues in the housing assembly
  • Air trapped in the cooling system after service

Installation Notes and Tips

Verify the 180 degree F temperature rating and housing dimensions before installation. Replace the thermostat with the included rubber seal, and orient the jiggle pin weep hole according to the vehicle service procedure so trapped air can escape during refill. Always bleed the cooling system fully after service and confirm there are no leaks at the sealing flange.

Quality Assurance

Motorad manufactures this thermostat with OEM-quality materials and safety standards as an OE supplier. It is produced to OEM specifications and processes for consistent fit and temperature response in demanding automotive cooling systems.
