Integrated Temperature Control for Audi Coolant Flow
The wax-actuated valve stays closed during early warm-up and opens as the calibrated temperature range is reached. The surrounding housing directs coolant through the correct engine and radiator passages.
An integrated assembly reduces the need to transfer an old valve into a new cover, but it also makes OE suffix, calibration and passage layout critical fitment details.
Audi OE Suffix, Passage and Calibration Checks
Confirm 06E121111AT against the VIN, engine code and production date. Related suffixes such as AN, AR or AS should be treated as catalogue leads, not automatic substitutes.
Compare housing shape, bolt locations, coolant passages, valve orientation and seal placement. Verify the required opening-temperature specification before approving a replacement.
Valve Movement and Housing-Seal Examination
Inspect the spring, guide and valve plate for alignment, and review the housing for cracks or warped mounting points. All gasket surfaces should be clean and protected.
Install with new approved seals and the correct tightening pattern. Use the specified coolant and bleeding procedure, then monitor warm-up data and system pressure.
Procurement, Packing and Sample Confirmation
Reference 06E121111AT as the OE identifier and THH260727-005 as the internal item code. Include required volume, destination, carton marking and label format in the quotation request.
Before batch supply, buyers may submit VIN data, engine information, measurements and photographs of the removed component. A physical sample can be used when catalogue evidence is incomplete.
Frequently Asked Questions
Does 06E121111AT include the thermostat housing?
Common listings describe it as a thermostat supplied with the housing and sealing components, but package contents should be confirmed before ordering.
Why is no Audi Model selected?
The source covers multiple Audi and related VAG platforms, so VIN, engine code and production date are required for exact approval.
Are 06E121111AN, AR and AS direct replacements?
They are related references seen in catalogues, but suffix interchange must be validated for the specific vehicle and engine.
What technical points should be compared?
Check OE suffix, valve calibration, passage layout, mounting points, housing material, seal locations and overall profile.
What is needed for an Audi wholesale quotation?
Provide 06E121111AT, THH260727-005, order quantity, destination, packaging instructions and vehicle data for fitment review.
