Detailed Description
URO 3528273 is a molded HVAC heater hose made to match the original hose shape used on select Volvo 850, S70, and V70 models. The EPDM rubber construction is specified for durability in hot engine-bay conditions and for resistance to ozone and electrochemical degradation, which can weaken heater hoses from the inside out. Its molded profile supports correct routing in the engine-to-heater inlet path and helps maintain the factory-style appearance of the hose assembly. This part number, 3528273, is a direct replacement option for Volvo heater hose service where the original hose has aged, softened, or cracked.
This part cross-references URO-002689 for the same application.
Common Problems This Part Can Address
- Coolant seepage at a worn heater hose
- Cracking or hardening from heat cycling
- Loss of heater performance caused by restricted coolant flow
- Improper hose routing after a previous repair
- Rubber deterioration from electrochemical breakdown
Installation Notes and Tips
Fits 1993-1997 Volvo 850, inlet - engine to heater. Fits 1998 Volvo S70, inlet - engine to heater. Fits 1998 Volvo V70, inlet - engine to heater.
