Rein CHR0349R Radiator Coolant Hose - Upper

OE-Style Upper Radiator Hose for Volvo

The Rein CHR0349R radiator coolant hose is an OE-quality replacement for select Volvo upper hose applications. It is built to match the original hose shape, branch layout, and quick-connect fitment used on the vehicle, helping restore proper coolant routing on Volvo C30, C70, S40, and V50 models.

Designed for European vehicle cooling systems, this branched radiator hose uses EPDM construction and a heat shield for added durability in demanding engine-bay conditions. The CHR0349R is a direct-fit solution for upper radiator hose replacement on 2004-2013 Volvo applications.

Detailed Description

Rein CHR0349R is engineered as an OE-quality radiator coolant hose for European vehicles, with dimensions and branch geometry that follow the original Volvo design. The hose is shaped for upper radiator hose service and uses the same style of quick-connect interfaces found on the factory assembly, which helps maintain proper sealing and fitment on Volvo C30, Volvo C70, Volvo S40, and Volvo V50 models. This part number, CHR0349R, is a practical choice when replacing a worn or leaking upper hose assembly.

This hose is application-specific and built for direct installation without cutting, refitting, or adjusting the hose. It is also designed to reduce installation time and avoid leaks caused by reusing old quick connectors and O-rings. This part cross-references Genu 30723082 and interchange 30650750 for the same application.

What It Helps Fix

• Coolant leaks at the upper radiator hose connection
• Cracked, swollen, or heat-damaged hose material
• Seepage from worn quick-connect fittings or O-rings
• Poor fitment after using a universal hose in place of the OE assembly
• Cooling system service on Volvo C30, C70, S40, and V50 upper hose routing

Installation Notes

Fits 2007-2013 Volvo C30, Upper. Fits 2006-2013 Volvo C70, Upper. Fits 2004-2011 Volvo S40, Upper. Fits 2005-2011 Volvo V50, Upper.

Before installation, inspect the mating connectors, seals, and surrounding cooling system components for wear or contamination.
