Injectors, high-pressure pump and cooling on the Terracan 2.9 CRDi

Sources are not verified in real time and no entry confirms that your car is affected.

Engine / equipment: Hyundai Terracan 2.9 CRDi diesel (J3)
Period mentioned: 2001–2007
Symptoms: Rough running, loss of power, smoke or knocking under load; diesel leaking at the injectors; overheating.
Possible cause described: Owner forums in Germany, Australia and South Africa repeatedly report injectors out of tolerance (all four, on a 250,000 km car), leaks at new injectors and failing high-pressure pumps, often with poor-quality diesel. Check the air-flow meter before replacing parts: one owner replaced the turbo, pump and injectors without curing the power loss. Overheating from the thermostat, water pump or radiator is also mentioned.
Check for the garage: Run an injector back-leak test with a diagnostic tool; check the air-flow meter and the fuel filter; watch the temperature and coolant level.
