Replace a worn or heat-damaged coolant reservoir hose with this URO engine coolant reservoir hose, part number 3531884. It is shaped for direct OE-style recovery tank hose fitment on select Volvo 740, 760, 780, 940, and 745 applications.

Key Features

• Precision-molded to match the OE recovery tank hose shape for straightforward installation
• Engine heat and ozone resistant for underhood durability
• ECD-resistant EPDM construction helps resist electrochemical degradation from the inside out
• Temperature rated from -40°F to 275°F (-40°C to 135°C)
• Guaranteed fitment for listed Volvo applications
• URO part number 3531884

Detailed Description

This engine coolant reservoir hose is built for the lower tank-to-radiator connection on select Volvo cooling systems. It is a direct replacement for the original hose shape, helping maintain proper coolant routing between the recovery tank and radiator on 1987-1991 Volvo 740, 1989-1991 Volvo 780, 1991 Volvo 940, 1987-1990 Volvo 760, 1986 Volvo 740, and 1985-1986 Volvo 760 and 745 models with water cooled turbocharger notes where listed. This part number 3531884 is also cross-referenced to Genu 3531884.

What It Helps Fix

• Coolant seepage at a cracked or hardened reservoir hose
• Loss of hose flexibility from heat and ozone exposure
• Internal rubber breakdown caused by electrochemical degradation
• Poor sealing at the tank-to-radiator hose connection
• Fitment issues from using an incorrect hose shape

Installation Notes and Tips

Verify the vehicle year, model, and lower hose routing before installation. This hose is listed for lower position applications and should match the OE recovery tank hose shape on the specified Volvo cooling system. Inspect the radiator neck, reservoir outlet, and adjacent cooling components for wear before installing the new hose.

Quality Assurance

URO backs this coolant reservoir hose with a 24 month unlimited mileage warranty. The EPDM material is engineered for resistance to heat, ozone, and electrochemical degradation, supporting long-term service in demanding cooling system conditions.
