engine?\u003c\/strong\u003e\u003cbr\u003e\nA: Check the compatible engine models table above to verify your engine series (2001–2003 models). You can also compare the OEM part number 966903 with your current belt or consult your engine's service manual.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How often should I replace the alternator belt?\u003c\/strong\u003e\u003cbr\u003e\nA: Inspect your belt every 100 operating hours or annually. Replace it if you notice cracking, glazing, fraying, or excessive wear. Most belts require replacement every 2–3 years under normal operating conditions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What are the signs that my alternator belt is failing?\u003c\/strong\u003e\u003cbr\u003e\nA: Common symptoms include squealing noises during engine operation, visible cracks or wear on the belt surface, battery warning lights on the dashboard, or insufficient charging voltage. Replace the belt immediately if any of these signs appear.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How tight should the belt be after installation?\u003c\/strong\u003e\u003cbr\u003e\nA: The belt should have a deflection of approximately 10–15 mm when pressed firmly at the longest span between pulleys. Over-tightening can damage bearings; under-tightening can cause slippage and reduced charging efficiency.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Is this an OEM or aftermarket belt?\u003c\/strong\u003e\u003cbr\u003e\nA: This listing is an aftermarket replacement part.
