The oil pump is the heart of your truck’s engine. A failure in the lubrication system doesn't just mean downtime—it often leads to catastrophic engine damage. The VG1246070040 Oil Pump Assembly is a precision-engineered component essential for maintaining steady oil pressure in Sinotruk WD615 and D12 engines.

In our experience managing HOWO parts distribution, we recommend paying attention to these common oil pressure signs:

Low Oil Pressure Warning: If your dashboard light flickers at idle, it’s often a sign that the oil pump gears or the pressure relief valve inside the VG1246070040 is worn.
Engine Noise: Unusual ticking or grinding from the lower engine block can indicate oil starvation caused by a failing pump.
Oil Contamination: When replacing the oil pump, always flush the oil galleries and replace the oil filters. Debris from a previous engine failure can quickly destroy a brand-new pump.
