This part cross-references Gates 34843 for the same application.

Common Problems This Part Can Address

  • Coolant temperature regulation issues caused by a worn thermostat
  • Cracked or leaking thermostat housing
  • Fault codes related to thermostat performance or coolant temperature control
  • Improper engine warm-up or unstable operating temperature
  • Seal leakage at the thermostat housing interface

Installation Notes and Tips

Verify the vehicle’s production date and OE thermostat specification before installation, especially on 2011-2013 Mini Cooper and Cooper Countryman applications that may require an adapter on earlier builds. Confirm the outlet port layout, bolt-hole count, and seal condition during replacement. Clean the mating surfaces thoroughly and inspect adjacent coolant hoses, sensors, and connectors before reassembly.
