Detailed Product Information
URO 4876371 is an HVAC heater hose made from EPDM rubber and formed to the original equipment profile for the Saab 9000 upper heater hose location. The molded design helps the hose follow factory routing, which is important for clearance, fitment, and a correct underhood layout. This hose is specified for the 1992-1998 Saab 9000 and is listed for two upper-position applications: water pump to heater on 1992-1993 models and connector to cylinder head on 1994-1998 models. URO 4876371 is also built with ECD-resistant EPDM to help reduce internal rubber breakdown caused by electrolysis.
This part cross-references OE-style numbers such as 40 28 593 and 43 59 725 for the same application.
Common Replacement Reasons
- Cracked or hardened heater hose rubber
- Coolant seepage at the hose body or ends
- Incorrect routing from a previous repair
- Heat-related hose swelling or softening
- Loss of heater circuit flow due to hose deterioration
Installation Notes
Confirm the hose routing and connection points before installation, since Saab 9000 upper heater hose applications vary by model year. Inspect adjoining coolant fittings, clamps, and nearby components for wear or corrosion before reassembly. Verify that the hose follows the molded OE path without twisting so the heater circuit maintains proper clearance and flow.
Quality Assurance
URO 4876371 is backed by a 24-month unlimited mileage warranty. The hose is engineered for guaranteed fitment and is rated for temperatures from -40°F to 275°F, making it a direct replacement choice for Saab 9000 heater hose service.
