New Turbocharger Replacement – Renault 1.5 dCi (K9K-THP)

Restore the fuel efficiency and signature low-end torque of your vehicle with this brand-new premium replacement turbocharger. Specifically engineered for the 1.5 dCi K9K-THP engine (100–103 HP), this unit is a precision-manufactured solution designed to handle the higher boost pressures of the high-power 1.5-liter diesel variants.

Detailed Vehicle Compatibility & Power Output

This turbocharger is a direct 1:1 replacement for the following models equipped with the 1.5 dCi engine:

Technical Specifications & Cross-Reference

This unit replaces the BorgWarner/KKK BV39 series. Verify compatibility using the following identification numbers:

Key Product Features

• 100% Brand New: Zero-mileage unit. Every component—from the high-grade turbine housing to the internal CHRA (core)—is factory-new.
• VSR High-Speed Balancing: Every core assembly is balanced at high speeds to eliminate vibrations, ensuring a long service life and quiet operation across the RPM range.
• Precision Actuator Calibration: The wastegate/actuator is pre-set to factory specifications to ensure stable boost pressure and prevent ECU "Overboost" errors.
• Fuel Efficiency Optimized: Designed to match the airflow requirements of the K9K-THP engine for optimal combustion and low emissions.

Critical Installation Requirements

The 1.5 dCi engine requires specific care during turbocharger replacement:

1. Oil & Filter Service: Always perform a full oil service during installation. Use only high-quality synthetic oil that meets Renault RN0710 (or RN0720 if equipped with a DPF) specifications.
2. Prime the Turbo: Before the first engine start, fill the turbo’s oil inlet port with clean oil and manually rotate the compressor wheel to ensure the bearings are lubricated.
3. Inspect the Oil Feed Line: Check the oil supply pipe for carbon buildup or restrictions. A restricted oil feed is the leading cause of premature turbocharger failure in 1.5 dCi engines.
4. Air Intake Check: Ensure the air filter is new and the intake hoses are free of debris from the previous failure.
