Detailed Product Overview

Use the URO GRH624 when replacing a worn or damaged radiator coolant hose in a vehicle cooling system. Its molded construction supports a direct OE-style replacement for select applications, including BMW and Mercedes-Benz fitments where exact hose routing and shape matter. The GRH624 part number is also useful when cross-shopping radiator hose replacements for the same application.

This part cross-references CH4281 and CHA616 for the same application.

What This Hose Helps Address

• Coolant leaks from cracked, hardened, or split hose rubber
• Restricted coolant circulation caused by hose collapse or internal deterioration
• Cooling system service needs after age-related EPDM wear
• Fitment issues from hoses that do not match OE routing or shape

Installation Notes and Tips

Inspect the mating necks, clamps, and adjacent cooling components before installation. Drain coolant as needed, transfer the hose along the original routing, and verify that the hose seats fully without twisting or kinking. Confirm application details by vehicle year, make, and model before ordering the GRH624.
