Product Technical Specifications

Fitment and OE Number Verification

Cooling-system components can vary by engine, transmission, production date and destination market. OE 5Q0121253J is supplied as an identification reference and must be checked against the removed unit.

• Confirm 5Q0121253J and any visible cross-reference number.
• Verify AUDI A3, model year and engine specification.

Cooling Function and Replacement Information

The radiator transfers heat from circulating coolant to the air moving through the core. Correct coolant flow and an unobstructed fin surface support stable operating temperature under normal working conditions.

Leakage, damaged tanks, restricted fins or recurring high coolant temperature can indicate service is required. Hoses, pumps, thermostats, fans and other system faults should also be inspected before replacement.
