Honda Civic Care 101: Learn More about the Serpentine Belt Idler Failure
As years go by, the Honda Civic gets better and better. Because of its strong reliability, safety, and comfort, it continues to be at the top of its class. Its solid road manners and excellent fuel economy make it an inexpensive, fuel-sipping commuter. However, like most cars, it has one common issue that many owners have complained about, and it\'s when the serpentine belt idler bolt fails.
The serpentine belt, the idler bolt, and the tensioner
The serpentine belt is one long, snaking, winding belt that keeps most of your car\'s components, including the alternator, power steering pump, and air conditioner, running smoothly and effectively. It is held tightly by an idler bolt and a tensioner. These two components work together to maintain the correct amount of tension on the serpentine belt at all times throughout its duty cycle. They also help protect other components that the belt keeps running to prevent undue stress and premature failure. When the belt tensioner is near failure and needs to be replaced, you also need to replace the idler bolt before it fails too. Look out for rust, worn pulley or bearing, misaligned tensioner, squeaks and rattles, excessive swaying of the tensioner arm, binding or grinding tensioner arm movement, and more.
Troubleshooting and fixing a serpentine belt idler bolt failure
In order to fix a failed serpentine belt idler bolt of your Honda Civic, you mostly need to look at the entire tensioner assembly. This is because a faulty part of the tensioner.the idler bolt being one of them.means that the rest of the assembly are about to fail soon, too. If you find rust bleeding between the arm and base or dripping from the component, then both tensioner and bolt are worn and need to be replaced. When checking the serpentine belt, manually rotate the pulley, and you notice noise, resistance, or roughness, then the bearing or pulley are defective. If that\'s the case, you will need to replace the entire tensioner assembly. Meanwhile, if you notice the serpentine belt tracking on the tensioner pulley in an unusual way, then the mounting bracket might be bent or misaligned. You must have this diagnosed and fixed by a mechanic that has a laser alignment tool, and if the problem persists, you must replace the tensioner.
Ways to prevent a serpentine belt idler bolt failure
Because the idler bolt is part of the tensioner assembly, you need to keep the assembly well-maintained. Whenever you have your Honda Civic serviced or when you do your own routine inspection, you must inspect the serpentine belt to make sure that all of the components are in working order. If you find a worn component, replace the entire tensioner assembly to prevent further problems. You should also replace the idler bolt and tensioner assembly if you hear an unusual squeaking or grinding sound every time you start the engine.
While the bolt is simply a tiny accessory, remember that it is part of a component that powers your car\'s air conditioning, power steering, and alternator. If the idler bolt falls off or breaks, then important parts of your vehicle are affected. Follow these maintenance tips to avoid any inconvenience in the future.
