The bank two catalytic converters are on the opposite side.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Catalytic Converter Location Diagram<\/h3>\n\n\n\n<p>Are you ready to locate your car&rsquo;s catalytic converter?

In other instances, the converter might bolt into place but be difficult to remove because its fasteners have become rusted and seized.<\/p>\n\n\n\n<p>If you&rsquo;re dealing with a bolt-in catalytic converter, it&rsquo;s a good idea to soak the fasteners in penetrating oil (preferably overnight) before removal. If you find the bolts are still difficult to remove after a good soak, you will likely need to use a propane torch and more penetrating oil&nbsp; (or possibly even an oxy-acetylene torch) to break the fasteners free.<\/p>\n\n\n\n<p>Here&rsquo;s a helpful video about how catalytic converters work:<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"How Catalytic Converters Work | CarParts.com Parts Explained with Lucas Ventures\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/xTEtkOxowQM?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>You can also check out these videos for tips on how to replace your catalytic converter:<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"How to replace the Catalytic Converter 2009-2014 Ford F150 &#128763;\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/Zu7mbaq60-I?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"How to replace the Catalytic Converter 2009-2018 Dodge RAM 1500 &#128763;\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/ZTwjAjq4Iz4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<!-- Error, Advert is not available at this time due to schedule\/geolocation restrictions! -->\n<\/body><\/html>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Reading Time: <\/span> <span class=\"rt-time\"> 2<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>You&rsquo;ve probably heard of a part of your car&rsquo;s exhaust system called the catalytic converter.
