FAQ
Q: How do I verify that this DE12 nozzle sleeve will fit my engine? A: To confirm compatibility, please check your existing nozzle sleeve’s part number and compare dimensions with the specifications listed above. The DE12 designation applies to Doosan’s 12-liter diesel engine platform. If you have your engine serial number or the original part number, our technical support team can assist with cross-referencing to ensure correct fitment for your specific application.
Q: What are the signs that my nozzle sleeve needs replacement? A: Common indicators of a worn or damaged nozzle sleeve include fuel leakage around the injector area, hard starting, rough engine idle, decreased fuel efficiency, excessive smoke from the exhaust, and loss of engine power. If you notice any of these symptoms, inspect the nozzle sleeve and replace it if necessary to prevent further damage to the fuel injection system.
Q: What installation precautions should I take? A: When installing the new nozzle sleeve, ensure the cylinder head bore is clean and free of debris. Apply a light coating of clean engine oil to the outer surface of the sleeve before installation. Use appropriate tools to avoid damaging the sleeve during insertion. Follow the manufacturer’s torque specifications for the injector hold-down clamp. After installation, check for proper fuel system priming and bleed any air from the system before starting the engine. We recommend having a qualified diesel technician perform the installation if you are not experienced with fuel system components.
