328-2573 Fuel Injector — Cat D6T

This is a fuel injector, responsible for precisely atomizing and delivering diesel fuel into the engine's combustion chamber at the correct time and pressure. Manufactured to meet OEM quality standards, it ensures optimal fuel combustion and engine performance, unlike a clogged or leaking injector that causes poor fuel economy and rough running. Observable symptoms of a faulty fuel injector include rough idling, reduced engine power, increased exhaust emissions, and difficulty starting the engine.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A rough or uneven engine idle, accompanied by a noticeable drop in power, are the first signs of a failing fuel injector. If ignored, the issue can progress to increased fuel consumption, excessive smoke, and potential engine misfires, leading to reduced operational efficiency and increased wear on other engine components. Persistent injector failure can result in uneven cylinder loading and potential damage.

Installation Tip

Ensure the injector bore in the cylinder head is perfectly clean and free of carbon deposits before installing the new injector. Avoid rotating the injector while seating it, as this can damage the sealing surfaces.

Service Note

Inspect the fuel lines, fuel filter, and fuel pump for proper operation when replacing a fuel injector.
