Bentley GT GTC Turbocharger Right 07C145061H

For the Bentley Continental GT and GTC (2003–2010), the part number 07C145061H identifies the Right-Hand (Passenger Side) turbocharger. This unit is part of the twin-turbocharged 6.0L W12 engine system and is manufactured by BorgWarner (specifically the K16 series).

1. Technical Specifications

The right-side turbo is distinct from the left side due to the specific orientation of the exhaust manifold and oil/coolant lines.

• Manufacturer: BorgWarner (K16-2467GAAAK5.82GAAXB)

• Configuration: Integrated Exhaust Manifold (the turbo and manifold are one cast piece).

• Cooling: Water-cooled bearing housing and oil-lubricated.

• Actuation: Vacuum-controlled wastegate actuator.

2. Common Symptoms & Diagnostic Tips

Before replacing the turbo, it is critical to confirm the failure is mechanical.

• Blue Smoke: Excessive blue smoke from the right-side tailpipe often indicates a failed internal oil seal.

• Underboost Codes: If you see “Boost Pressure Regulation: Range Not Reached” (P0299), check the vacuum lines first. The braided lines behind the engine are known to perish, which prevents the wastegate from closing properly.

• Wastegate Rattle: A metallic rattling sound upon deceleration often indicates a worn wastegate flapper valve, which is a common issue on high-mileage K16 units.

3. Installation & Labor Notes

Warning: Replacing turbochargers on a W12 Bentley is an extremely labor-intensive task.

• Engine-Out Procedure: Standard repair manuals require the removal of the engine and transmission to access the turbochargers, as they are located at the rear of the engine block against the firewall.

• Replace in Pairs: Because of the labor costs associated with an engine-out service, many specialists recommend replacing or refurbishing both the left and right turbos simultaneously to avoid a second teardown later.

• Oil Feed Lines: Always replace the oil feed and return lines when installing a new turbo to prevent immediate failure from sludge or debris blockage.
