OE-Style Lower Radiator Hose for Audi A4

The Rein CHR0608 is an OE quality radiator coolant hose for European vehicles, built as a direct replacement for the original lower hose assembly. It is shaped for the application and uses thermoplastic quick connect fittings to help restore a secure cooling system connection on Audi A4 and Audi A4 Quattro models.

Compatible with 2002-2006 Audi A4, lower, and 2002-2005 Audi A4 Quattro, lower, this Rein radiator hose is designed for a precise OE-style service fit. The CHR0608 helps reduce installation time while maintaining the branch size, shape, and connector style expected for the application.

  • Direct replacement for the lower radiator coolant hose assembly
  • OE-style branched hose design with application-specific fitment
  • Thermoplastic quick connect fittings for proper connection points
  • EPDM hose construction for heat and contamination resistance
  • Black finish with OE-style routing and branch geometry
  • Rein CHR0608 for Audi A4 and Audi A4 Quattro cooling system service

Detailed Product Overview

Rein CHR0608 is engineered to match the original hose layout used on select Audi A4 and Audi A4 Quattro lower cooling system applications. The hose measures 22 inches centerline length and uses a branched configuration with two large hose ends and one smaller branch, matching the OE-style routing needed for the lower radiator circuit. Rein’s OE quality approach focuses on dimensional accuracy, including the branch shape and quick connect fittings, so the replacement follows the factory design rather than requiring modification.

This part cross-references Genuine 8E0121049N and 8E0121055 for the same application.

What This Hose Helps Address

  • Cracked or aged lower radiator hose material
  • Coolant leaks at the hose or connector interface
  • Fitment issues caused by non-OE hose shaping
  • Installation delays from cutting, refitting, or adjusting the hose
  • Repeat cooling system service from reusing worn quick connectors or O-rings

Installation Notes and Tips

Verify the vehicle application before installation, especially the lower hose routing on 2002-2006 Audi A4 and 2002-2005 Audi A4 Quattro models. Inspect mating connectors and sealing surfaces before assembly, and replace worn O-rings or damaged quick-connect components as needed to maintain a proper seal. Confirm hose routing clears nearby components and follows the original path.

Quality Assurance

Rein positions this hose as an OE quality replacement for European vehicles, with construction intended to match the original hose assembly used by the manufacturer. The EPDM material is selected for resistance to heat, salt, road debris, oil, and other contaminants. Rein CHR0608 includes a 24-month or 24,000-mile warranty.
