As we know, the cooling system always maintains and regulates this regardless of the circumstances and the ambient temperature. And for this important task it is necessary, among other components, the <a href=\"https:\/\/www.idolz.com\/en\/thermostats\/\" target=\"_blank\" rel=\"noopener\">thermostat<\/a>, <strong>responsible for blocking and allowing the coolant flow to the cooling radiator.<\/strong><\/p>\n<p>In today&#8217;s article we get to know its simple but necessary mechanism and discover its key elements of this small component.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Operation and types of thermostats<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>Among the main functions of the thermostat are to <strong>accelerate engine warm-up blocking cooling <\/strong>and <strong>to regulate the temperature by opening and closing its mechanism <\/strong>in response to specific changes in coolant temperature to keep the engine\u2019s temperature.<\/p>\n<p>For this, there are different kinds of thermostats depending on the vehicle application. And its mechanism differs from each other.<\/p>\n<ul>\n<li><strong>Conventional <\/strong>thermostat<\/li>\n<\/ul>\n<p>Formed by a spring, this kind of thermostats are characterized by containing alcohol inside and thus actuate their mechanism <strong>by the volatility<\/strong> and not through the expansion of a liquid.<\/p>\n<p>When the cooling liquid reaches a high temperature, there is a liquid-vapour transition that expands the spring.<\/p>\n<ul>\n<li><strong>Wax-type <\/strong>thermostat<\/li>\n<\/ul>\n<p>Its main element is an <strong>encapsulated wax, thermally expansive<\/strong> and in contact with the cooling liquid. Its mechanism is based on expansion.<\/p>\n<p>Upon reaching a specific temperature, this wax melts and expands the capsule, opening the valve that gives way to the cooling liquid. As it cools, it contracts again, closing the mechanism.<\/p>\n<ul>\n<li><a href=\"https:\/\/www.idolz.com\/en\/map-controlled-thermostat\/\" target=\"_blank\" rel=\"noopener\"><strong>Map-controlled thermostat<\/strong><\/a><\/li>\n<\/ul>\n<p><strong>Controlled by the engine\u2019s electronic control unit (ECU)<\/strong>, these thermostats operate their mechanism based on the engine\u2019s loads.<\/p>\n<p>This kind of thermostat allows some benefits like reduced fuel consumption and lower pollution emissions by improving engine efficiency.<\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<p style=\"text-align: center;\"><em>Related content: <\/em><a href=\"https:\/\/www.idolz.com\/en\/official-unboxing-of-the-new-dolzs-automotive-thermostats\/\" target=\"_blank\" rel=\"noopener\"><em>Video Unboxing: new Dolz\u2019s thermostats<\/em><\/a><\/p>\n<\/blockquote>\n<p><strong>\u00a0<\/strong><\/p>\n<h2><strong>Key elements of a thermostat<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>The basic parts of a thermostat are:<\/p>\n<ul>\n<li><strong>Frame and Housing:<\/strong> includes a <strong>valve attached to the piston.<\/strong><\/li>\n<li><strong>Flange: <\/strong>located in the body.<\/li>\n<li><strong>Spring<\/strong>: keeps the valve closed when the coolant is not hot.<\/li>\n<li><strong>Wax element<\/strong>: thermostat core.<\/li>\n<\/ul>\n<p><img class=\"size-medium wp-image-9713 aligncenter\" src=\"https:\/\/www.idolz.com\/wp-content\/uploads\/2021\/12\/termo-300x215.jpg\" alt=\"termostato\" width=\"300\" height=\"215\" srcset=\"https:\/\/www.idolz.com\/wp-content\/uploads\/2021\/12\/termo-200x143.jpg 200w, https:\/\/www.idolz.com\/wp-content\/uploads\/2021\/12\/termo-300x214.jpg 300w, https:\/\/www.idolz.com\/wp-content\/uploads\/2021\/12\/termo-400x286.jpg 400w, https:\/\/www.idolz.com\/wp-content\/uploads\/2021\/12\/termo-600x429.jpg 600w, https:\/\/www.idolz.com\/wp-content\/uploads\/2021\/12\/termo.jpg 682w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>To avoid entrapment of air and hot spots, <strong>many thermostats have a jiggle pin or check valve that allows trapped air in the cooling system<\/strong> to pass through the thermostat and be released.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<h2><strong>Failing thermostats<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>Among the <a href=\"https:\/\/www.idolz.com\/en\/5-thermostat-failure-symptoms-and-how-to-avoid-them\/\" target=\"_blank\" rel=\"noopener\">thermostat failure symptoms<\/a>\u00a0are those related to stuck.
