As a professional supplier of HOWO parts, we recommend these three diagnostic checks for your VG1246060013 idler:

Noise Inspection: If you hear a high-pitched chirping or grinding sound when the engine is idling, it’s often a sign that the internal lubricant of the idler pulley has degraded.
Visual Alignment: Ensure the belt sits perfectly centered in the six slots. If the belt is riding up against the edge, it may indicate a worn bracket or a failing idler bearing.
Spin Test: With the belt removed, spin the pulley by hand. It should spin smoothly and silently. Any "dry" spinning or wobbling indicates it is time for an immediate replacement to avoid a roadside breakdown.
