Later, the components were all concentrated in one unit. | Image Source: Richard McCuistian<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What Is the EGR Tube?<\/h2>\n\n\n\n<p>The EGR tube directs gases from the <a href=\"https:\/\/www.carparts.com\/exhaust-manifold\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"exhaust manifold\">exhaust manifold<\/a> through the EGR system. It recycles them back to the combustion chamber where they&rsquo;ll be burned.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Symptoms of a Bad EGR Tube<\/h2>\n\n\n\n<p>The EGR tube works directly with the engine, so it pays to know the signs it&rsquo;s time to replace it. They include:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Rough Idling<\/h3>\n\n\n\n<p>An open EGR tube lets very little or too much exhaust gas into the combustion chamber. This messes with the air and fuel mixture, causing the engine to idle roughly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Engine Stalling<\/h3>\n\n\n\n<p>Rough idling can also <a href=\"https:\/\/www.carparts.com\/blog\/car-shuts-off-while-driving-causes-what-to-do\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"cause the engine to stall\">cause the engine to stall<\/a> or die out when idling.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Knocking Sounds<\/h3>\n\n\n\n<p>A closed EGR tube locks the gases inside the combustion chamber. They cause high temperatures and early ignition at low RPMs, which produce a knocking sound from the engine.<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Illuminated Check Engine Light<\/h3>\n\n\n\n<p>The check engine light illuminates when the car computer detects issues.

The exhaust gasses passing through the EGR tube contain carbon and other elements that accumulate. The buildup can get sticky, preventing the EGR tube from opening or closing properly. However, as stated earlier, the tube itself isn&rsquo;t where the clogging happens.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Long Does an EGR Tube Last?<\/h2>\n\n\n\n<p>The EGR tube has no set service life, but experts recommend getting a carbon cleaning or air induction procedure every 50,000 miles. The process removes the buildups in the tube and its supporting connections, keeping them from clogging the passageways.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Should I Clean or Replace the EGR Tube?<\/h2>\n\n\n\n<p>If your EGR tube is dirty, cleaning it would solve most issues. However, if it&rsquo;s damaged or there are other problems reducing its performance, it might be better to replace it.<\/p>\n\n\n\n<p>Also, remember that a bad EGR tube can affect the parts around it. If it&rsquo;s been faulty and causing issues for a while, the parts around it might also need repairs or replacement.<\/p>\n\n\n\n<p>If you take your vehicle to an auto repair shop, mechanics would also check other system parts, like the <a href=\"https:\/\/www.carparts.com\/egr-valve\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"EGR valve\">EGR valve<\/a>, <a href=\"https:\/\/www.carparts.com\/egr-cooler\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"EGR cooler\">EGR cooler<\/a>, EGR cooler bypass, and intake throttle valve.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can I Clean the EGR Tube Myself?<\/h2>\n\n\n\n<p>While cleaning the EGR tube yourself can save money, it can also cause costly problems if done incorrectly. It involves removing, cleaning, and reinstalling the tube. Mistakes in any of the steps can worsen existing issues and affect the entire EGR system.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can I Replace the EGR Tube Myself?<\/h2>\n\n\n\n<p>With the right tools and know-how, you can replace the EGR tube in your garage. However, similar to cleaning, taking the DIY approach is risky if you don&rsquo;t know what you&rsquo;re doing. So if you&rsquo;re not confident you can do it yourself, it&rsquo;s best to leave the task to a licensed mechanic.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Is It Worth Getting an EGR Tube Repair Kit?<\/h2>\n\n\n\n<p>It&rsquo;s always a good idea to invest in repair kits for any damaged component &ndash; especially for a component as vital to a vehicle as the EGR tube. These repair kits contain all the parts, gaskets, seals, and mounting kits needed to replace the damaged EGR tube of a vehicle.<\/p>\n\n\n\n<p>If it&rsquo;s not taken care of, a vehicle&rsquo;s EGR tube is vulnerable to cracks, leaks, and corrosion. This means it&rsquo;s important to have replacements ready in the event your vehicle&rsquo;s EGR tube is damaged beyond repair.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Final Thoughts<\/h2>\n\n\n\n<p>The EGR tube is a crucial part of the EGR system, so you must ensure it stays in great condition. If you spot any of the signs that point to its failure, take your ride to an auto repair shop to address problems immediately.<\/p>\n\n\n\n<p>Mechanics can determine whether your EGR tube needs cleaning or replacement, and they can do the service as well. You can also count on them to identify and prevent potential problems in case the EGR tube has affected other parts.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Get a Replacement EGR Tube<\/h2>\n\n\n\n<p>While you can fix a clogged EGR tube by cleaning it, you must replace a damaged tube. Furthermore, it&rsquo;s best to stop driving your vehicle to avoid causing more costly problems with the exhaust system. It&rsquo;s a good thing you can easily find a replacement EGR tube that fits your vehicle at CarParts.com.<\/p>\n\n\n\n<p>Shopping for replacement EGR tubes at <a href=\"https:\/\/www.carparts.com\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"CarParts.com\">CarParts.com<\/a> is simple and easy.
