KIMISS engine coolant thermostat housing assembly 06B121111K
Product description
During a cooling-system repair, matching the replacement part to the one already fitted matters as much as choosing the right type of component. The KIMISS engine coolant thermostat housing assembly is listed for the 2002–2006 A4 Quattro and is intended to replace OE part number 06B121111K.
Its job is to regulate engine temperature through the coolant system. The listing describes a plastic-and-metal assembly, but gives no further material breakdown or installation details.
Key specifications
This is a thermostat and housing assembly, rather than a standalone thermostat. The stated replacement reference is 06B121111K, and the product name identifies the A4 Quattro from 2002 to 2006. The description also refers to models from those years, but does not list trims, engine variants or other vehicle applications. Match the part number and your vehicle’s exact configuration before ordering, a year range alone may not settle fitment.
The housing is described as being made from plastic and metal. No dimensions, seal details or individual component materials are provided, so there is not enough information to compare its construction closely with a specific original part. Its stated purpose is to help control engine temperature and guard against overheating, but that depends on correct fitment and the condition of the rest of the cooling system.
Who it’s for
Te encaja si you are replacing an existing thermostat housing assembly and can confirm that 06B121111K is the matching reference for your vehicle. For example, during a cooling-system repair, you could compare the number on the removed part with this listing before fitting the replacement. That is a more targeted approach than choosing a generic thermostat by vehicle year alone.
Puede no ser la mejor opción si you need confirmed compatibility for a particular engine or trim, or want installation instructions and details about seals or fasteners before starting the job. Those specifics are not supplied. If you are unsure about the part number, checking the vehicle’s parts information or asking a qualified parts professional is a sensible step.
In the box
The stated package contents are one engine coolant thermostat housing assembly. The listing does not confirm whether separate seals, fasteners or other installation parts are included. If your repair plan depends on replacing those items too, allow for the possibility that they may need to be sourced separately rather than assuming they come in the package.
Before you decide
Which part number is this intended to replace? The listed OE reference is 06B121111K. Compare it with the part required for your vehicle.
What material is the assembly made from? The description says plastic and metal, without identifying which components use each material.
Does the package include more than the assembly? Only one thermostat housing assembly is specified, other included parts are not detailed.
Veredicto final
This KIMISS assembly is worth considering for a replacement job when the OE reference and vehicle application match. Its stated role and package contents are straightforward, but the listing leaves useful fitment and installation details unanswered. If you need a confirmed match for a specific engine configuration or a clearly itemized set of seals and hardware, get those details before choosing it. If the part number checks out and you only need the assembly, its focused replacement format may suit the repair.
