An apparatus (30) for adding coolant (64) to a cooling system of a motor vehicle includes a cap (32) with a resilient sleeve (82) that expands against the inside wall of a radiator filler neck (24) to provide an airtight connection. A valve (36) attached to the cap (32) controls the flow of air and coolant through the cap (32). A gauge (34) on the cap (32) indicates the pressure inside the radiator (20). A venturi assembly (44) connected to the valve (36) provides a source of vacuum (40) for evacuating air from the cooling system. Thereafter, coolant (64) is drawn through the cap (32) by the vacuum created in the system.

L'invention concerne un appareil (30) permettant d'ajouter un liquide de refroidissement (64) au système de refroidissement d'une automobile. Cet appareil comporte un capuchon (32) pourvu d'un manchon élastique (82) qui s'expanse contre la paroi intérieure du goulot de remplissage d'un radiateur (24) afin de créer une connexion étanche à l'air. Une soupape (36) fixée au capuchon (32) régule l'écoulement d'air et de liquide de refroidissement à travers le capuchon (32). Une jauge (34) située sur le capuchon (32) indique la pression à l'intérieur du radiateur (20). Un ensemble venturi (44) connecté à la soupape (36) forme une source de vide (40) permettant d'évacuer l'air du système de refroidissement. Le liquide de refroidissement (64) est ensuite aspiré à travers le capuchon (32) par le vide créé dans le système.
