The core of your engine’s functionality relies on key components like the **Air Compressor**, vital for brake and pneumatic systems, and the **Generator**, which ensures a steady supply of electrical power. The **Starter Motor** provides the crucial ignition spark to get your engine running smoothly. For relentless temperature control, the **Water Pump** is indispensable, circulating coolant to prevent overheating and maintain peak operating conditions.
Protect your engine from harmful contaminants with our **Air Filter Assembly**, which safeguards against abrasive particles, and the **Oil-Water Separator and Joint Assembly**, a critical part for purifying fuel and preventing injector damage. For proactive system monitoring, the **Water Level Sensor Assembly** provides early warnings for low coolant, helping you avoid costly repairs and downtime.
Don’t overlook the importance of auxiliary components. The **Belt Tensioner Pulley** ensures optimal tension for the serpentine or timing belt, preventing slippage and ensuring that all driven accessories function harmoniously and reliably.

Proper maintenance and servicing are critical to maximizing the performance, fuel efficiency, and lifespan of your Dongfeng engine. Adhering to a scheduled regimen ensures reliability and helps avoid costly downtime.
* **Service:** Inspect every 15,000 km; replace every 30,000-50,000 km or as indicated by the **air filter restriction sensor**. In dusty environments (e.g., mining in Chile, farming in Zambia), clean the housing and check/replace the filter more frequently.
* **Warning:** A clogged filter restricts airflow, causing power loss, increased fuel consumption, and potential turbocharger damage.
* **Service:** Check coolant level weekly. Flush the cooling system and replace the coolant every 2 years or 200,000 km. Inspect the **water pump** for leaks (at the weep hole) and unusual noise during routine servicing. The **water level sensor** should be tested for proper warning light function on the dashboard during ignition checks.
* **Warning:** Mixing incompatible coolants can cause gel formation and overheating. Never open a hot radiator cap.
* **Service:** Drain the accumulated water from the separator bowl daily or as prompted by the warning light. Replace the entire filter cartridge every 20,000-30,000 km, or according to fuel quality. In regions with poor fuel quality (common in many areas), service intervals must be shortened.
* **Warning:** Failure to drain water leads to injector corrosion, fuel system damage, and engine stalling.
* **Service:** Change engine oil and the full-flow oil filter at strict intervals, typically every 10,000-15,000 km or 500 hours. Always use the recommended oil grade and viscosity (e.g., API CI-4/CH-4 15W-40).
* **Warning:** Extended oil change intervals are the primary cause of sludge buildup, accelerated engine wear, and failure.
* **Service:** Inspect for oil and coolant leaks during every service. Replace seals (e.g., valve cover, front crankshaft, turbocharger oil return line) anytime the component is removed or if a leak is detected. Use only genuine gaskets.
* **Warning:** Small leaks can quickly develop into major ones, leading to low oil pressure and severe engine damage.
* **Service:** Inspect the serpentine/accessory belt for cracks, glazing, and fraying every 15,000 km. Check the **belt tensioner pulley** for smooth rotation and any bearing noise. Replace the entire belt and tensioner kit as a set at the recommended interval (often 90,000 km) to prevent catastrophic failure.
