OEM Infiniti Belts

Refine Results

The more moving parts and systems at work in your INFINITI vehicle, the more belts you'll find helping them operate in peak condition.

The Types of Belts

Not counting the seat belts that secure you and your passengers, there are three kinds of belts: a timing belt, serpentine belts, and drive belts.

The timing belt is a notched belt that connects the crankshaft to the camshaft. It helps them move in sync, while also protecting parts from banging into each other. If it breaks, you'll know right away since your engine will stop working. Recent models may feature a timing chain instead of a belt, though; these can last the engine's entire lifetime.

Serpentine belts team with the tensioner, crank pulley, and idler pulley to run such parts as your power steering and alternator. Drive belts, or V-belts, run off the crank pulley and move parts like the radiator, water pump, and more. If either of these types of belts break, you generally have some time to repair the problem before things get too serious.

How to Identify Bad Belts

Check your belts regularly to ensure that they're in good condition. Signs of failure include:

  • Fraying belt edges
  • Cracks in the belt material
  • Belts that are too loose or too tight
