This application discloses a coolant system for a vehicle engine which may be retrofitted if desired, the coolant system including a coolant flow circuit (14) which in part includes passage means (15) through an engine block (10) of the vehicle engine and through a heat exchanger (12), the coolant system further including a coolant pump (22) which, when operated, causes coolant flow around the coolant flow circuit (14), the coolant pump (22) being driven by an electric motor (M) independently of the vehicle engine, the coolant system still further including a coolant temperature sensor (23) and controller means (C) whereby differing voltage levels are supplied to the motor (M) in response to differing coolant temperature levels being sensed by the coolant temperature sensor (23).

La présente invention concerne un système de refroidissement destiné à un moteur. En cas de besoin, ce système peut être ajouté après coup. Le système de refroidissement comprend un circuit de refroidissement (14) intégrant notamment un dispositif de circulation (15) établi dans la masse du carter (10) du moteur de l'automobile et dans la masse d'un échangeur thermique (12). Ce système de refroidissement comporte en outre une pompe (22) dont le fonctionnement fait circuler le fluide de refroidissement dans le circuit de refroidissement (14). Cette pompe de refroidissement (22) est mue par un moteur électrique (M) indépendant du moteur de l'automobile. Le système de refroidissement comporte en outre une thermosonde (23) du fluide de refroidissement et des organes de commande (C). Ces derniers permettent de faire varier le niveau de la tension électrique fournie au moteur (M) en réaction aux variations de la température du fluide de refroidissement détectée par ladite thermosonde (23).
