\"24\"<\/a>Le circuit de refroidissement joue un r\u00f4le primordial dans le bon fonctionnement du moteur d\u2019une voiture. En effet, les pi\u00e8ces m\u00e9caniques m\u00e9talliques d\u2019un moteur produisent un \u00e9chauffement extr\u00eamement important qui doit \u00eatre obligatoirement refroidi. Il existe deux mani\u00e8res de refroidir un moteur sur une voiture : par air ou par eau. Le refroidissement permet d\u2019\u00e9viter la surchauffe moteur, avec toutes les cons\u00e9quences qui en d\u00e9coulent : d\u00e9formation des pi\u00e8ces moteur, casse du joint de culasse, baisse des performances, usure pr\u00e9matur\u00e9e du moteur\u2026<\/span><\/p>\n

Mais le liquide de refroidissement a aussi pour r\u00f4le de maintenir le moteur \u00e0 une temp\u00e9rature stable dites temp\u00e9rature \u201coptimale\u201d de fonctionnement. Il permet ainsi au\u00a0 moteur de ne pas \u00eatre trop chaud ni trop froid et de procurer ainsi ses meilleures performances.<\/span><\/p>\n

Quand renouveler son liquide de refroidissement?<\/h2>\n

C\u2019est pourquoi, dans le cas d\u2019un refroidissement par eau, il est extr\u00eamement important de renouveler r\u00e9guli\u00e8rement son liquide de refroidissement. Cela est d\u2019autant plus vrai dans le cas d\u2019une utilisation en comp\u00e9tition, o\u00f9 les moteurs sont mis \u00e0 rudes \u00e9preuves et o\u00f9 les surchauffes sont tr\u00e8s fr\u00e9quentes. Pour une utilisation normale, il est g\u00e9n\u00e9ralement pr\u00e9conis\u00e9 de changer son liquide de refroidissement tous les 3 ans ou 50 000 km<\/strong>. Bien s\u00fbr, en condition de course ou bien si le v\u00e9hicule n\u2019est pas utilis\u00e9 r\u00e9guli\u00e8rement, il faudra renouveler le liquide plus souvent.\u00a0<\/span><\/p>\n

Pour \u00eatre le plus efficace possible, le remplacement du liquide de refroidissement doit se faire en 3 \u00e9tapes :\u00a0<\/span><\/p>\n

    \n
  1. Nettoyage du circuit de refroidissement. C\u2019est une \u00e9tape qui est trop souvent n\u00e9glig\u00e9e. Elle consiste \u00e0 m\u00e9langer un produit dans l\u2019ancien liquide de refroidissement qui va permettre de dissoudre les boues, oxydes et tartre qui se sont progressivement form\u00e9s dans le circuit de refroidissement et qui g\u00eanent le passage du liquide. Ce produit va permettre de r\u00e9tablir un fonctionnement optimum du syst\u00e8me (pompes, radiateur, thermostat) et d\u2019optimiser les \u00e9changes de temp\u00e9rature.\u00a0<\/span><\/li>\n
  2. Remplacement du liquide de refroidissement par un liquide de refroidissement<\/a> neuf.<\/span><\/li>\n
  3. Ajout d\u2019un additif permettant \u00e0 la fois de baisser la temp\u00e9rature du liquide et de prot\u00e9ger le circuit de refroidissement de l\u2019oxydation et \u00e9viter ainsi la formation de boue.<\/span><\/li>\n<\/ol>\n

    Bien souvent, seule l\u2019\u00e9tape b est r\u00e9alis\u00e9e et elle ne suffit pas \u00e0 r\u00e9tablir un fonctionnement optimal du syst\u00e8me de refroidissement.<\/span><\/p>\n
