Detailed Description

Rein CHR0438 is a complete OE quality direct-fit European hose for the cooling system. It is engineered to match the original radiator hose used on 2002-2009 Volvo S60, 2002-2007 Volvo V70, 2003-2007 Volvo XC70, and 2002-2004 Volvo C70 upper hose applications. The hose follows the factory size and shape, including the thermoplastic quick-connect ends, so the replacement installs like the original part rather than a universal hose.

This radiator coolant hose measures 12 inches centerline length and uses EPDM construction for durability in high-temperature engine bay conditions. Rein CHR0438 is a practical choice when servicing a Volvo upper radiator hose that needs accurate fitment, stable sealing, and OE-style routing. This part cross-references Monroe Shocks & Struts (e.g., 8771393, 30680912) for the same application.

Common Problems This Hose Can Address

• Coolant leaks at the upper radiator hose connection
• Cracked, swollen, or heat-aged hose material
• Damaged quick-connect fittings or worn O-rings
• Poor fit from universal hose replacements
• Repeat cooling-system repairs caused by reused connectors

Installation Notes and Tips

Verify the vehicle application before installation and compare the original hose routing, connector style, and end dimensions to the new part. The direct-fit design eliminates cutting and refitting, which helps reduce installation time on Volvo S60, V70, XC70, and C70 upper hose service. Inspect mating surfaces, clamps, and seals during replacement to ensure a clean, leak-free connection.

Rein designs this hose as an OE-quality replacement for European vehicles, with factory-style dimensions and connector details. Part number CHR0438 is backed by a 24-month or 24,000-mile warranty.
