Description
Turbocharger for Citroën and Peugeot vehicles with 2.0 HDI RHR RHE RHJ engines.
High-quality Garrett turbocharger designed as a direct replacement for 2.0 HDI engines used in a range of Citroën and Peugeot models. This unit restores boost pressure, improves engine response and performance, and is cross-referenced with the common OE and aftermarket codes listed below. Ideal for professional workshops and experienced DIY mechanics searching by part number (e.g. 0375J1, 0375K1) to find a reliable swap for a worn or failed turbo.

Function and Benefits
The turbocharger uses exhaust gas energy to drive a turbine connected to a compressor wheel that forces more air into the engine. This increases combustion efficiency and torque, particularly at low and mid engine speeds. Benefits include improved throttle response, better driveability and recovery of lost performance compared to a worn unit. The turbo is oil-lubricated and relies on a clean, steady oil supply and proper cooling to function reliably.
Replacement Procedure (Overview)
Replacement should be performed by a qualified mechanic or an experienced DIYer with appropriate tools. General steps:
- Allow the engine to cool. Work on a cold engine to avoid burns.
- Disconnect the battery.
- Remove intake and intercooler piping to access the turbo.
- Drain or isolate coolant if applicable and disconnect coolant lines to the turbo.
- Disconnect oil feed and return lines; be prepared to catch residual oil and replace gaskets.
- Support the turbo and remove mounting nuts/bolts to the exhaust manifold/downpipe.
- Install the replacement turbo with new gaskets, seals and hardware. Use manufacturer torque specifications for fasteners.
- Prime the oil supply before initial start (crank engine with fuel disabled or by other safe priming method) to prevent dry start damage.
- Check for oil, coolant and boost leaks. Start engine, allow to idle until oil pressure stabilizes, then check again and perform a gentle road test.
Installation Recommendations
Always replace turbo oil feed and return gaskets, and inspect the oil lines for blockage or wear. Use fresh engine oil and a new oil filter at installation. Torque all fasteners to the manufacturer’s specification and replace any seized or corroded studs. Prime the turbo’s oiling system before the first start to avoid bearing damage. After installation, avoid heavy loads or high engine speeds for the first few minutes of operation to allow proper oil circulation and seating.
Most Common Failure Reasons
Turbo failures on 2.0 HDI units are most commonly caused by oil-related issues (contamination, coking, oil starvation), foreign object damage from the intake or exhaust side, excessive soot and soot build-up in diesel applications, worn bearings and oil seal leaks. Symptoms include loss of boost, excessive smoke, unusual whining noises, and oil consumption. Regular oil and service intervals, clean air intake, and prompt repairs of oil or cooling leaks help extend turbo life.
Service Life and Notes
Service life varies with maintenance and driving conditions; properly maintained turbochargers on modern diesel engines often exceed 150,000 km, but units exposed to poor maintenance, frequent short trips, or contaminated oil can fail much earlier. Because this product is commonly searched by part number, verify the code (0375J1 / 0375K1 / 0375K8 / 0375K9) and OE cross-references (9645919580, 9654919580, 9663201280, 9682778680) to ensure correct fitment for your engine variant.
