What is the pulley next to the alternator?
A serpentine belt is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, air conditioning compressor, air pump, etc.
Where does the serpentine belt go on an alternator?
If you do not have a diagram on the vehicle or in your service manual laying out the direction your serpentine belt travels through the pulleys, take a picture of it with your phone to refer to when installing the new belt. A strictly alternator belt will likely only go around an alternator pulley and the crank pulley at the bottom of the engine.
How does an alternator pulley work in a car?
At the same time it is fixed to the alternator itself. When the engine is running, the drive belt helps to turn the pulley which in turn drives the alternator. The alternator produces a low voltage electricity that the car uses for the headlights, the radio or the air-conditioning.
What’s the best way to loosen an alternator belt?
Use a breaker bar or socket wrench to loosen the auto-tensioner. Many newer model vehicles come equipped with an auto-tensioner pulley. The pulley presses upward as the belt wraps around it so the belt remains under constant, steady tension.
Which is the best belt for alternator and fan?
So cars went from one belt driving the fan, water pump, and alternator, to 2 or 3 separate belts, now also driving the power steering pump, A/C compressor, and emissions air pump. The “V” belt is one of the most effective belt solutions because of its strength, relative quietness, power transfer, and durability.

Where is the alternator belt on a Toyota 4Runner?
The fan/water pump to alternator belt is the closest to the engine block. If you need to replace this belt, the other two belts will have to be removed first, starting with the belt furthest from the engine block (the power steering vane pump belt), then the A/C compressor belt before you can finally get to the alternator belt.
