Description

Garrett turbo GTC1244VZ (reference 9686120680, 0375P7 / 0375P8) is a direct-fit replacement for the 1.6 e-HDI diesel engines used across several Citroën and Peugeot models. Designed to restore engine boost response, torque delivery and drivability, this turbocharger provides OE-compatible fitment and mounting points for a straightforward swap on compatible vehicles. Oil feed pipe is not included; reuse or replace the original oil feed/return lines and sealing gaskets during installation to ensure reliable lubrication and long service life.

Features & Benefits

• Direct replacement for OE-referenced turbochargers, designed for 1.6 e-HDI engines.
• High-quality Garrett manufacture for durable performance and precise balancing.
• Restores factory boost levels and driveability when replacing a worn or damaged turbo.
• Compatible with original mounting, sensor and actuator interfaces for easier installation.

Compatible Models

• Citroën C4 (including C4 II)
• Citroën C4 Picasso
• Peugeot 308
• Peugeot 3008 I
• Peugeot 5008 I

Installation And Replacement

Replacement of the turbocharger should be performed by a trained technician or an experienced DIY mechanic with the correct tools. Typical replacement steps:

• Allow the engine to cool completely. Relieve intake pressure and disconnect the battery if required by the vehicle service procedure.
• Remove intake and intercooler pipes to gain access to the turbocharger.
• Drain engine oil to avoid contamination when disconnecting oil feed and return lines. Note: Oil feed pipe is not included with this turbo—inspect and replace the pipe and seals if worn or blocked.
• Disconnect oil and coolant lines (if applicable), vacuum hoses and electrical connectors to sensors or actuators attached to the turbo.
• Unbolt the turbocharger from the exhaust manifold and downpipe, transfer any required brackets, sensors or actuators to the new unit if not supplied.
• Fit new gaskets and seals on all connections. Torque bolts to manufacturer specifications and verify correct alignment.
• Before first start, prime the turbo oil supply by cranking the engine with fuel/ignition disabled or by pre-filling the turbo oil gallery where possible to prevent dry start damage.
• Start the engine, idle until oil pressure is stable, check for oil/leakage and exhaust leaks, then perform a controlled test drive and recheck fasteners and connections.

Most Common Failure Causes

• Oil starvation or contaminated oil leading to bearing wear—often caused by overdue oil changes, clogged oil feed or return lines, or blocked oil filters.
• Carbon and soot buildup from EGR or poor combustion that restricts oil passages or fouls the turbine/compressor.
• Foreign object damage to the compressor or turbine wheels (ingestion from intake side or exhaust backflow).
• Boost leaks, failed actuator or vacuum lines causing over‑stress or incorrect turbo operation.
• Excessive thermal stress from repeated overheating or improper warm-up/cool-down habits.

Installation Recommendations

• Always replace oil and oil filter before and shortly after turbo replacement to remove contaminants.
• Inspect and, if necessary, replace oil feed and return pipes, seals and gasket sets to ensure unrestricted lubrication.
• Use manufacturer torque values and follow the vehicle service manual for sequence and tightening stages.
• Prime the turbo with oil prior to first start and avoid heavy engine load or high RPM for the first few minutes of operation.
• Check related systems (EGR, PCV, intercooler and intake piping) that can cause premature turbo deterioration if faulty.
