What It Helps Address

• Cracked or aged coolant breather pipe routing
• Coolant seepage at the reservoir-to-radiator or reservoir-to-connector path
• Improper coolant circulation through the upper hose routing
• Heat-related deterioration in the original pipe assembly
• OE-number mismatch during Mercedes-Benz cooling system repair

Installation Notes

Verify the OE number on the original part before installation, especially on Mercedes-Benz S550, S600, S65 AMG, CL550, and S450 models. Confirm the routing location shown in the fitment notes: upper reservoir-to-radiator or reservoir-to-connector applications. Inspect adjoining cooling system connections for wear, residue, or damage before installing the new pipe.
