Product Details

VAICO V10-3788 is an intercooler hose made for the hot-side charge-air path, where consistent airflow and secure sealing are critical. The rubber body with textile reinforcement helps maintain shape under boost-related heat and pressure, while the stainless steel compression ring material supports a secure connection at the hose interface. This part cross-references Dorman - HELP 82684 for the same application.

VAICO is the product line identified here as VAICO, and this hose follows the OE-style fitment expected for Volkswagen turbo cooling and charge-air routing. It is a practical replacement for worn, cracked, or leaking hose assemblies on 2006-2009 Volkswagen Passat, 2009 Volkswagen CC, and 2009 Volkswagen Passat CC vehicles with OE No. 3C0145834K.

Common Problems This Part Can Address

• Boost leaks caused by a split or deteriorated intercooler hose
• Loss of turbo response from damaged charge-air plumbing
• Oil mist or residue around a leaking hot-side hose connection
• Cracked rubber from heat cycling and age
• Loose or unreliable sealing at the pipe-to-intercooler joint

Installation Notes and Tips

Confirm the OE number and hose routing before installation, especially on 2009 Volkswagen CC, 2009 Volkswagen Passat, and 2009 Volkswagen Passat CC models built to 04/30/2009. Inspect adjoining pipes, clamps, and sealing surfaces for wear before fitting the new hose. Proper alignment at the hot-side intercooler connection helps prevent boost leaks and repeat failures.

Quality Assurance
