• Description:

  Genuine Audi OEM Lower Hose Retainer Spring is a small but critical component in your vehicle's cooling system, securing hose couplings firmly in place to prevent coolant leaks and maintain consistent pressure throughout the system. Designed to fit a range of Audi vehicles, this retainer spring ensures the upper and lower coolant hose connections stay locked and properly seated under the thermal expansion and vibration demands of everyday driving. Also referred to as an Upper Hose Retainer Spring, Coupling Spring, or Coupling Retainer Spring, this clip-style component must maintain precise tension to function correctly. Aftermarket versions are frequently manufactured from lower-grade spring steel that loses tension over time, allowing hoses to shift, weep coolant, or disconnect entirely — a failure that can lead to rapid overheating and costly engine damage. The Audi OEM version 1J0121142 is engineered to exact factory tolerances, using the correct material grade and spring rate to deliver a secure, lasting hold that aftermarket alternatives simply cannot guarantee. Whether you're searching for an Audi OEM Lower Hose Retainer Spring or the replacement part number 1J0-121-142, Audi Henderson, an authorized Audi dealer, offers this genuine factory part backed by the manufacturer's warranty for complete confidence in every repair.
