Product Details

The Motorad 11-53-1-721-966 is a replacement engine coolant thermostat housing designed to restore proper cooling system function. This housing serves as the main structural enclosure that retains the thermostat and connects to the engine block, directing coolant flow to maintain optimal operating temperature.

OEM part number 11531721966 is a well-known wear item on BMW M42-engined vehicles. Over time, prolonged exposure to high-temperature coolant can cause the original plastic housing to become brittle, crack, or develop leaks — making timely replacement essential to prevent overheating and coolant loss.

Key Features:

  • Direct-fit replacement for the OEM thermostat housing
  • Engineered to meet or exceed OEM specifications for fit, form, and function
  • Restores proper coolant flow and engine temperature regulation
  • Manufactured by Motorad, a trusted supplier in the automotive cooling system market
  • Bolt-on installation for straightforward servicing

OEM & Cross-Reference Part Numbers:

  • 11-53-1-721-966
  • 11531721966
  • 11.53.1.721.966
  • 11 53 1 721 966

Also commonly referred to as a connection flange, hose connector, or engine coolant thermostat housing. A replacement gasket (OEM ref: 11 53 1 721 172) is recommended during installation.

Got the order fast and got it installed just in time for a fishing trip.....thanks bostplicity.

Fast shipping, excellent product! Ordered the new SPC upper control arm ball joints and my truck rides like new again, Thank you!

Just as described. Fast service

We got the tire in time!

I was pretty happy with the service. I ordered the part on a Sunday afternoon and paid $9.99 for 2 day delivery and it arrived on Friday 5 days later so not sure I got what I paid for in that regard.

Excellent quick delivery

Great price, easy ordering process.
