How to Change a Serpentine Belt in a Toyota Highlanderby Jennifer T
The serpentine belt, one of the most important parts of any engine, is a single belt that drives multiple components which are connected to the motor. If it wears out, it's impossible to drive your car. Fortunately, you can change the serpentine belt on a Toyota Highlander with just a few standard tools.
Park the vehicle in the well lighted work space and open the hood. Let the vehicle cool completely before you begin repairing. Locate the belt diagram under the hood to give you a visual guide.
Remove cover from over the alternator with your adjustable wrench.
Locate the hexagon bolt in the middle of the alternator. Securely place your socket wrench on the bolt and turn it counterclockwise. The belt will begin loosening. The more you turn the nut, the more slack you will have to remove the belt.
Pull the belt off of the alternator and continue removing it from around the other pulleys. Track your steps while removing the belt, because installing the new belt is the reverse of installation.
Install the new belt on to the alternator looping it onto the other pulleys.
Tighten the bolt on the alternator until the belt is semi tight around all of the pulleys. Guide the belt with your free hand while you are tightening it so it doesn't come off the pulleys.
- Print out a diagram of your belt system. If you cannot find it online, take a clear picture of the diagram under your hood and print the picture out.
