Drive belt tensioners come in a variety of designs, but maintain one common goal, to keep the drive belt (or serpentine belt) tight and able to deal with the torque created by the crankshaft pulley, alternator, water pump, power steering pump, and other system components. A faulty tensioner may allow the belt to slacken, causing a loud squeal as the belts slip on the pulleys. This can manifest into a potentially dangerous situation if the belt were to come loose and fall off, losing all accessory power.

About this Belt Tensioner & Idler Pulley

The GENUINE PORSCHE 94810226100 is part of the accessory drive that runs the alternator, A/C compressor and other components. The tensioner keeps the drive belt at the right tension and idler pulleys guide it, and their bearings wear over time.

Frequently asked questions

What does a belt tensioner do?

It applies constant pressure to the drive belt so it grips the pulleys without slipping, and it absorbs the belt's movement as engine speed changes. Idler pulleys guide the belt around its path.

What are the signs of a worn tensioner or idler pulley?

A squeal or chirp from the front of the engine, a rumbling or grinding bearing noise, a belt that flutters, jumps or wears unevenly, or a tensioner arm that bounces or has visible play.

What should I replace along with it?

Replace the drive belt at the same time, and consider replacing the other pulleys if they have similar mileage, since their bearings wear at a similar rate.

Can I replace a tensioner myself?

Usually, yes. Note or photograph the belt routing before removing it, release the tension with the correct tool, and check the new belt sits correctly in every pulley groove before starting the engine.

How do I make sure this belt tensioner or pulley fits my car?
