Performance Features
1. **Strong Heat Dissipation Stability:** The flow rate is precisely matched to engine speed, ensuring uniform heat dissipation in the cylinder block at idle. Under high-speed, heavy-load conditions, it quickly removes engine waste heat, preventing overheating and making it suitable for high-intensity scenarios such as long-distance logistics and engineering operations.
2. **Excellent Wear and Durability:** The cast iron pump body and impeller are resistant to coolant corrosion, and the sealing structure effectively prevents leakage. Performance degradation is slow and service life is long within the range of -15℃ low-temperature start-up to 110℃ high-temperature operation.
3. **Good Installation Compatibility:** Fully complies with MAN engine original factory installation standards, requiring no modification to mounting holes or piping. It can directly replace old original parts, making it suitable for original factory assembly and after-sales maintenance scenarios for Sinotruk and compatible brand vehicles.
Usage and Maintenance Precautions
1. Pre-installation Inspection: Before installation, verify that the water pump model matches the engine batch and emission stage. Check that the impeller rotates smoothly and that the seals are intact to avoid malfunctions caused by incompatible parts or damage during transportation.
2. Installation Specifications: Installation must be performed by a professional mechanic. During installation, ensure the pump body fits tightly against the cylinder block and tighten bolts to the specified torque. After connecting the cooling lines, bleed the air to prevent air blockage and ensure effective heat dissipation.
3. Medium Requirements: Only use engine coolant that meets original equipment manufacturer (OEM) standards. Do not add tap water or inferior coolant. Adjust the coolant ratio according to the season and change it regularly to prevent scale buildup and corrosion inside the pump body.
4. Operation and Maintenance: Regularly check the water pump belt tension and sealing. If coolant leakage, abnormal pump noise, or abnormal engine coolant temperature occurs, repair or replace the affected components immediately. Avoid prolonged engine overload operation to reduce water pump wear.
5- Safety Warning: When performing maintenance or replacement, disconnect the power supply and cool the engine first. Wait until the coolant temperature drops to room temperature before proceeding to prevent burns from hot coolant splashes. Do not disassemble the water pump yourself, as this will result in seal failure and void the warranty.
