However, the reason your car\u2019s losing coolant is far from magical: it\u2019s almost always thanks to a <\/span><b>coolant leak<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There are three main causes for coolant leaks: external leaks, radiator cap leaks and internal leaks.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Common signs of a coolant leak<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The easiest way to identify if you have a coolant leak is by checking underneath the engine for any puddles that are forming when you\u2019re parked. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you notice one, keep an eye on your coolant levels as you drive. If they start dropping faster than normal, then you\u2019ve probably got a coolant leak on your hands!<\/span><\/p>\n<h3><span style=\"font-weight: 600;\">Can coolant leak cause check engine light to show?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Some car owners have also reported noticing the \u2018Check Engine\u2019 light displaying on the dashboard before identifying a coolant leak.\u00a0<\/span><\/p>\n<figure id=\"attachment_17649\" aria-describedby=\"caption-attachment-17649\" style=\"width: 300px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-17649 size-medium\" src=\"https:\/\/www.kseal.com\/wp-content\/uploads\/2020\/08\/Temp-Guage-300x197.jpg\" alt=\"A 'check engine' light glows on a car dashboard.\" width=\"300\" height=\"197\" srcset=\"https:\/\/www.kseal.com\/wp-content\/uploads\/2020\/08\/Temp-Guage-300x197.jpg 300w, https:\/\/www.kseal.com\/wp-content\/uploads\/2020\/08\/Temp-Guage.jpg 579w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><figcaption id=\"caption-attachment-17649\" class=\"wp-caption-text\">A &#8216;check engine&#8217; light on a dashboard.<\/figcaption><\/figure>\n<p><span style=\"font-weight: 400;\">This is because, when the coolant level is too low it obviously affects the temperature level in the engine. If the temperature sensor in the engine judges the coolant to be too low to effectively protect the engine, it will provide a false reading, and trigger the \u2018Check Engine\u2019 light.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">How to identify external coolant leaks<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Check your radiator hoses, the radiator and coolant reservoir or tank. Radiator hoses are common culprits, as the rubber hoses may degrade over time. Common signs of damage to these include swelling, cracks, unusual softness or holes.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-17661 aligncenter\" src=\"https:\/\/www.kseal.com\/wp-content\/uploads\/2020\/08\/Coolant_Hoses-300x195.jpg\" alt=\"\" width=\"300\" height=\"195\" srcset=\"https:\/\/www.kseal.com\/wp-content\/uploads\/2020\/08\/Coolant_Hoses-300x195.jpg 300w, https:\/\/www.kseal.com\/wp-content\/uploads\/2020\/08\/Coolant_Hoses.jpg 578w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">Generally, small holes in your radiator hoses or loose connections between hoses and the cooling system are the most likely cause of an external coolant leak.<\/span><\/p>\n<h3><span style=\"font-weight: 600;\">How to fix an external coolant leak<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">This should be fairly simple, and cost effective.

This is vital to ensuring that the mix of coolant and water designed can move through the system to cool the engine as needed. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">If the radiator cap is loose or leaking, this reduces the pressure and makes it harder for coolant to keep the engine from overheating.<\/span><\/p>\n<figure id=\"attachment_17673\" aria-describedby=\"caption-attachment-17673\" style=\"width: 300px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-17673 size-medium\" src=\"https:\/\/www.kseal.com\/wp-content\/uploads\/2020\/08\/Radiator_Cap-300x223.jpg\" alt=\"A close up of a car radiator cap.\" width=\"300\" height=\"223\" srcset=\"https:\/\/www.kseal.com\/wp-content\/uploads\/2020\/08\/Radiator_Cap-300x223.jpg 300w, https:\/\/www.kseal.com\/wp-content\/uploads\/2020\/08\/Radiator_Cap.jpg 523w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><figcaption id=\"caption-attachment-17673\" class=\"wp-caption-text\">A car radiator cap.<\/figcaption><\/figure>\n<p>You can diagnose this yourself by consulting your car owner\u2019s manual and checking the radiator cap to make sure it has the right pressure.
