Detailed Description

Rein CHR0367R is a single radiator coolant hose engineered for the lower cooling circuit on select Mercedes-Benz models. The hose follows OE dimensions, including branch shape and connector style, so it installs as a direct-fit replacement rather than a universal hose that requires trimming or adaptation. The EPDM construction is suited for engine bay heat and exposure to common road contaminants, while the quick connect design helps maintain the original connection style used by the vehicle manufacturer. If you are replacing a worn lower radiator hose on a Mercedes-Benz CL500, S430, or S500, CHR0367R provides the OE-style layout needed for a proper service repair.

Common Problems This Part Can Address

• Coolant seepage from an aged or cracked lower radiator hose
• Leaks at worn quick-connect fittings or o-rings
• Fitment issues caused by using a universal hose
• Service delays from cutting, refitting, or adjusting hose length
• Repeat cooling-system repairs from reusing damaged connectors

Installation Notes and Tips

Verify the lower hose routing and connector style against the original part before installation. CHR0367R is application-specific, so no cutting or reshaping should be required when installed on the listed Mercedes-Benz models. Inspect mating surfaces, clamps, and sealing points for wear before assembly, and replace any damaged seals or connectors as needed to prevent leaks.
