Product Details

This Gates Turbocharger Hose (Molded - Standard) is engineered as an intercooler hose for the cold-side charge-air path, where consistent sealing and shape retention matter.

If you are searching for a Mercedes-Benz GL350 intercooler hose or a Mercedes-Benz ML350 turbocharger hose, Gates 26552 is the OE-exact replacement to compare against the original part.

This part cross-references 1665280000 and R28610 for the same application.

What It Helps Address

• Boost-air leaks from a cracked or split intercooler hose
• Loss of charge-air pressure on turbocharged diesel engines
• Oil-soaked hose deterioration in the under-hood area
• Heat-related softening, swelling, or hose collapse
• Fitment issues caused by a distorted or non-OE molded hose

Installation Notes and Tips

Verify the hose shape, inside diameter, and centerline length against the original part before installation. Confirm the cold-side routing on the vehicle and inspect adjoining clamps, pipes, and sealing surfaces for wear or contamination. For Mercedes-Benz GL350 and ML350 turbocharger hose replacement, clean the connection points thoroughly so the hose seats evenly and maintains a secure seal.

Quality Assurance

Gates designs this hose with OE-exact dimensions and reinforced construction to match factory-style service requirements. The silicone cover is specified to withstand oil exposure, environmental contaminants, and elevated under-hood temperatures common in turbocharged applications.
