Frequently Asked Questions

Is this for the gas or diesel engine?
This specific thermostat and housing assembly is engineered strictly for the 3.0L TDI V6 (Diesel) engines. It will not fit the 3.0T Supercharged gas engines found in similar vehicles.
What is the difference between the AM, AK, R, G, and H part numbers?
Nothing except the production date! Volkswagen/Audi frequently updates part numbers to reflect minor manufacturing improvements, supplier changes, or updated gasket materials across production years. The numbers 059121737AM, 059121737AK, 059121737R, 059121737G, and 059121737H are all fully interchangeable factory revisions of this exact same thermostat assembly.
Does this include the housing and the gasket?
Yes. This part arrives as a complete unit, featuring the thermostat integrated directly into the housing, complete with the main sealing O-ring/gasket pre-installed.
Why is my heater blowing cold air on the highway?
If your heater blows hot around town but turns lukewarm or cold when you hit highway speeds, your thermostat is stuck open. At highway speeds, the massive amount of cold air rushing through the radiator overcools the continuously flowing coolant, preventing the engine block and heater core from retaining heat.
