Detailed Application Information

This heater hose is used in the coolant circuit that carries heated coolant between the heater core and pipe on the return side. For Audi A4, Audi A4 Quattro, and Volkswagen Passat applications, the URO 8D0819373N helps restore proper coolant flow through the HVAC system when the original hose is cracked, softened, or leaking. This part cross-references Gates 19793 for the same application.

Common Repair Symptoms

  • Coolant seepage near the heater core or firewall
  • Reduced or inconsistent cabin heat
  • Visible hose cracking, swelling, or hardening
  • Coolant odor inside or around the engine bay
  • Loss of coolant from the heater hose circuit

Installation Notes

Verify hose routing and connection points against the original part before installation. Inspect adjoining pipes, clamps, and heater core fittings for wear or corrosion, and replace any damaged components during service. Confirm the cooling system is properly filled and bled after installation to help prevent air pockets.
