But even if an old serpentine belt looks good, the truth is that it has a limited lifespan, so replacing it with a new belt can save you money in the long run.\u00a0 Thankfully, there are ways to improve the lifespan of the FEAD system.<\/p>\n<p>Read about these methods of improvement below.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Understanding the front-end accessory drive components<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>In automotive accessory belt drive systems, the crankshaft delivers mechanical power to critical engine accessories. That is the alternator, the power steering pump, the A\/C compressor, and (sometimes) the water pump. \u00a0As the belt needs to be really quite long you&#8217;re also likely to find an idler pulley, and\/or a <a href=\"https:\/\/www.idolz.com\/en\/tensioner-pulley\/\" target=\"_blank\" rel=\"noopener\">tensioner pulley<\/a> in the mix.<\/p>\n<ul>\n<li><strong>The poly-V belt<\/strong> is a composite made of elastomeric material layers, generally EPDM rubber, and a cord layer (fiber) and is used to drive the alternator and water pump by transmitting power from crankshaft pulley.<\/li>\n<li><strong>Idler-pulleys<\/strong> are often used in this type of transmission to increase the wrap angle around the pulleys and are available in various shapes and sizes depending on the application.<\/li>\n<li>The pulley systems on modern engines typically use an automatic tensioner. <strong>The tensioner<\/strong> is a self-tensioning device that applies tension to the aux belt, helping keep it taught in the various operating conditions. Also preventing it from slipping or jumping off other components.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2><\/h2>\n<h2><strong>Auxiliary System Maintenance Tips<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>Proper front-end accessory drive maintenance is important to keep equipment running as efficiently as possible and to keep the various drive components from wearing prematurely. Here are some maintenance tips to ensure your system is in tip top condition:<\/p>\n<ol>\n<li>As for when you need to replace these belts, there\u2019s no hard-and-fast rule. It varies depending on the vehicle and the conditions under which you drive. But formost\u00a0cars, it&#8217;s\u00a0recommended\u00a0that you get<strong> the serpentine\u00a0belt\u00a0inspected once your\u00a0car\u00a0reaches 60K miles<\/strong>. So, perform maintenance as scheduled with the vehicle manufacturer and\u00a0replace components before they wear out\u00a0and cause further damage to the vehicle.<\/li>\n<li>Inspect the system to make sure all components are aligned.\u00a0<strong>Use a laser alignment to ensure proper alignment<\/strong>.<\/li>\n<li><strong>Inspect belt and pulleys for signs of wear<\/strong>. Checking for cracks, fraying, splits or worn spots. Also, listen for unusual noises such as a chirping or squealing sound.<\/li>\n<li>The tension of your serpentine belt is a critical factor in its performance and longevity.\u00a0So, <strong>check the belt tension<\/strong>: it should be tight, with little or no give.<\/li>\n<li><strong>Replace all FEAD components at the same time<\/strong>. This helps prevent comebacks, reduces noise issues, and enhances overall system performance. In fact, replacing the belt alone rarely solves the customer complaint.<\/li>\n<\/ol>\n<p>With these easy tips, you can maximize the lifespan and performance of your auxiliary drive system. Don&#8217;t forget to consult your vehicle&#8217;s manual or seek professional advice for specific maintenance procedures.<\/p>\n<p>As we have pointed out on previous occasions the most obvious symptoms of failure of the auxiliary belt system are steering hardening, vehicle battery or A\/C failure or humming in the engine. For this reason, it is important that you must be able to identify the signs of a defective FEAD system due to its importance to the functioning and comfort of your car.<\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<p style=\"text-align: center;\">Related content: <a href=\"https:\/\/www.idolz.com\/en\/auxiliary-drive-belt-tensioner-for-hybrid-applications-skd250a\/\" target=\"_blank\" rel=\"noopener\">Auxiliary Drive Belt Tensioner for hybrid applications: DOLZ SKD250A<\/a><\/p>\n<\/blockquote>\n<p>&nbsp;<\/p>\n<h2><strong>DOLZ Auxiliary Drive Kits<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>In order to make your life easier and to secure effortless replacements, <strong>each OE-quality auxiliary drive belt kit includes all application-specific components needed to complete a front-end accessory drive (FEAD) system repair<\/strong>.
