Certains mod\u00e8les ATS, CTS, CT6, Camaro 2016-2017; LaCrosse, XT5 et Acadia 2017 \u00e9quip\u00e9s du moteur 3.0L V6 (EFC LGW) ou 3.6L V6 (EFC LGX) peuvent \u00e9mettre un bruit de cognement ou de battement sourd en provenance du compartiment moteur quand le moteur est chaud. Ce son peut \u00eatre d\u00fb au fonctionnement de la pompe \u00e0 d\u00e9pression m\u00e9canique du syst\u00e8me de freinage. Le son n’affecte pas la capacit\u00e9 de la pompe \u00e0 fournir une d\u00e9pression au servofrein ou la dr\u00e9e de vie de la pompe \u00e0 d\u00e9pression.<\/p>\n

Si le son semble provenir du compartiment moteur, d\u00e9marrer le moteur et le laisser tourner au ralenti jusqu’\u00e0 ce que la temp\u00e9rature atteigne 98\u00a0\u00b0C (208\u00a0\u00b0F).<\/p>\n

Si ce son est pr\u00e9sent, pomper les freins 3 \u00e0 5 fois pour v\u00e9rifier qu’il dispara\u00eet. Si le son dispara\u00eet, il reviendra peu de temps apr\u00e8s. Le son se produit quand le syst\u00e8me de servofrein est \u00e0 l’\u00e9quilibre (compl\u00e8tement tir\u00e9). Pomper les freins n\u00e9cessite que la pompe \u00e0 d\u00e9pression cr\u00e9e plus de vide pour compenser.<\/p>\n

Si le son dispara\u00eet lors de l’application des freins, remplacer la pompe \u00e0 huile. (Fig. 11) La pompe \u00e0 d\u00e9pression m\u00e9canique fait partie de la pompe \u00e0 huile \u00e0 l’int\u00e9rieur du carter d’huile est constitue la source de vide pour le syst\u00e8me de freinage.<\/p>\n
