Audi Coolant Pipe - Genuine Audi 06E121045BB
OEM Audi Coolant Pipe (Genuine Audi Part # 06E121045BB)
Restore factory cooling system reliability to your supercharged Audi powerplant with the Genuine Audi coolant supply and crossover pipe. Engineered specifically for the 3.0T V6 engine, this OEM component routes vital engine coolant between cylinder heads and directly to the upper radiator hose circuit, maintaining precise thermal regulation under high-performance driving conditions.
Over years of heat cycles and constant pressure, factory composite plastic coolant lines become brittle, prone to micro-cracking, and susceptible to coolant leaks. Replacing a failing or weeping pipe with this authentic OEM part ensures a seamless, leak-free fit that aftermarket alternatives often struggle to replicate.

NOTE: Direct replacement for factory part 06E121045BB and its predecessors (AA, AJ, AK revisions). Confirm your chassis code before ordering.
Note: Because aging plastic lines become exceptionally fragile, it is highly recommended to inspect surrounding O-rings, thermostats, and crossover components, and refresh your coolant at the time of replacement.
Coolant Pipe FAQ
Is this a direct bolt-on replacement?
Yes, it's manufactured to factory dimensions for precise alignment with your stock hoses, seals, and mounting tabs.
Which factory part numbers does this replace?
It cross-references Audi part 06E121045BB and its predecessor revisions ending in AA, AJ, and AK.
How do I know if my coolant pipe needs replacing?
Factory composite plastic lines become brittle with age and heat cycling, leading to micro-cracks, weeping, or an outright coolant leak. Visible coolant loss or an overheating condition are the usual signs.
What else should I inspect while replacing this pipe?
Since aging plastic lines are often exceptionally fragile, we recommend inspecting the surrounding O-rings, thermostat, and crossover components, and refreshing your coolant at the same time.
