Pour exploiter pleinement les performances de la voiture et garantir le confort de ses utilisateurs, l'entretien du ch\u00e2ssis est essentiel. La fr\u00e9quence des vidanges d'huile moteur, en particulier, joue un r\u00f4le important.<\/p>\n

Les diff\u00e9rentes fonctions de l'huile moteur<\/h2>\n

1. Lubrification : l'huile s'infiltre entre les surfaces m\u00e9talliques pour emp\u00eacher tout contact direct, r\u00e9duisant ainsi les frottements. Tout en pr\u00e9venant l'usure, elle contribue \u00e9galement \u00e0 la fluidit\u00e9 des mouvements.<\/p>\n

2. Protection anticorrosion : l'huile forme un mince film \u00e0 la surface du m\u00e9tal afin d'emp\u00eacher la corrosion et la rouille provoqu\u00e9es par les gaz corrosifs et l'humidit\u00e9.<\/p>\n

3. Refroidissement : l'huile absorbe et \u00e9vacue la chaleur g\u00e9n\u00e9r\u00e9e \u00e0 l'int\u00e9rieur du moteur afin d'\u00e9viter toute surchauffe de celui-ci.<\/p>\n

4. \u00c9tanch\u00e9it\u00e9 : l'huile s'infiltre entre la paroi du cylindre et le piston afin d'emp\u00eacher les fuites de gaz et de r\u00e9duire la pression d'explosion dans la chambre de combustion, jouant ainsi un r\u00f4le d'\u00e9tanch\u00e9it\u00e9.<\/p>\n

5. Nettoyage : l'huile permet d'\u00e9liminer les impuret\u00e9s, telles que les copeaux de meulage et les gaz accumul\u00e9s \u00e0 l'int\u00e9rieur du moteur, et de les disperser dans l'huile, ce qui permet de maintenir toutes les pi\u00e8ces du moteur propres.<\/p>\n

\"1\"<\/p>\n

Les risques li\u00e9s \u00e0 une vidange d'huile moteur effectu\u00e9e trop tard<\/h2>\n

1. Usure : l'usure de la chemise de cylindre entra\u00eene une augmentation de la consommation d'huile ;<\/p>\n

2. Usure accrue des paliers du vilebrequin et du m\u00e9canisme de soupapes ;<\/p>\n

3. D\u00e9p\u00f4ts de carbone : l'adh\u00e9rence des segments de piston entra\u00eene un mauvais fonctionnement du piston, ce qui se traduit par une baisse de la puissance du moteur et, dans les cas les plus graves, par un frittage ;<\/p>\n

4. Il y a un risque de corrosion.<\/p>\n

Inspection et entretien quotidiens du ch\u00e2ssis<\/h2>\n

1. V\u00e9rifiez le niveau d'huile :<\/p>\n

Le niveau d'huile doit \u00eatre v\u00e9rifi\u00e9 au moins 5 minutes apr\u00e8s l'arr\u00eat du moteur diesel ; il doit se situer entre les limites sup\u00e9rieure et inf\u00e9rieure de la jauge.<\/p>\n

2. V\u00e9rifiez le niveau du liquide de refroidissement :<\/p>\n

En particulier lors des travaux d'hiver, v\u00e9rifiez que le niveau d'antigel est suffisant et que le mod\u00e8le utilis\u00e9 est adapt\u00e9 \u00e0 la temp\u00e9rature la plus basse du climat local afin d'\u00e9viter que le r\u00e9servoir d'eau ne g\u00e8le.<\/p>\n

3. V\u00e9rifiez si le filtre \u00e0 air est encrass\u00e9 et nettoyez-le tous les jours.<\/p>\n

4. Quantit\u00e9 d'huile moteur \u00e0 verser (la quantit\u00e9 d'huile \u00e0 verser varie en fonction des diff\u00e9rents mod\u00e8les de moteurs)<\/p>\n

FM12 : 33 litres<\/p>\n

FM9 : 28 litres<\/p>\n

4. Norme relative \u00e0 l'huile moteur : VDS-2 ou VDS-3<\/p>\n

L'huile Shell VG150 est recommand\u00e9e<\/p>\n

5. Fr\u00e9quence de vidange d'huile moteur :<\/p>\n

Moteur D12D : 22 500 kilom\u00e8tres ou 10 000 litres d'huile, mais pas plus de 3 mois.<\/p>\n

Moteur D9A : 20 000 kilom\u00e8tres ou 7 000 litres d'huile, mais pas plus de 3 mois.<\/p>\n

\u00c9tapes \u00e0 suivre pour changer l'huile moteur<\/h2>\n

1. V\u00e9rifiez le niveau d'huile moteur sur une route plane, moteur arr\u00eat\u00e9. Si le v\u00e9hicule est en pente ou si le moteur tourne, la mesure du niveau d'huile ne sera pas fiable ;<\/p>\n

2. Avant d'ouvrir le bouchon du r\u00e9servoir, afin d'\u00e9viter que des corps \u00e9trangers ne s'y introduisent, il convient de nettoyer au pr\u00e9alable l'orifice de remplissage et la zone autour du bouchon ;<\/p>\n

3. Une fois l'huile moteur enti\u00e8rement vidang\u00e9e, il faut d\u00e9visser tous les bouchons de vidange suivants : (carter d'huile, filtre \u00e0 huile principal, filtre divis\u00e9, radiateur d'huile, etc.) ;<\/p>\n

4. Remplacer l'huile moteur lorsque le moteur est \u00e0 l'arr\u00eat mais encore chaud permet de gagner du temps, mais la temp\u00e9rature de l'huile reste \u00e9lev\u00e9e ; il convient donc de faire preuve de prudence lors de cette op\u00e9ration.<\/p>\n

Remarque : ne m\u00e9langez pas diff\u00e9rents types d'huile moteur.<\/p>\n

Le r\u00f4le du refroidissement et de l'antigel<\/h2>\n

1. Effet rafra\u00eechissant : refroidir le moteur pour \u00e9viter qu'il ne surchauffe ;<\/p>\n

2. Protection antigel : l'eau g\u00e8le \u00e0 0 \u00b0C, ce qui peut entra\u00eener la rupture du radiateur et de la chemise d'eau du moteur ; c'est pourquoi il est n\u00e9cessaire d'utiliser de l'antigel ;<\/p>\n

3. Effet anticorrosion : le syst\u00e8me de refroidissement comporte diff\u00e9rents types de m\u00e9taux, et l'antigel permet d'emp\u00eacher les temp\u00e9ratures \u00e9lev\u00e9es, les gaz corrosifs, etc. d'oxyder et de corroder ces m\u00e9taux ;<\/p>\n

4. Augmenter le point d'\u00e9bullition.<\/p>\n

Remarque : utilisez l'antigel Mobil ou Shell n\u00b0 45 comme liquide de refroidissement et antigel ; n'ajoutez pas d'eau.<\/p>\n

Les dangers li\u00e9s au fait de ne pas remplacer l'antigel \u00e0 temps<\/h2>\n

1. Provoque l'obstruction du radiateur ;<\/p>\n

2. Surchauffe du moteur ;<\/p>\n

3. Divers produits en caoutchouc sont sujets au vieillissement ;<\/p>\n

4. Fuites au niveau de la pompe \u00e0 eau ;<\/p>\n

5. M\u00e9lang\u00e9 \u00e0 l'huile moteur, ce qui provoque un frittage du moteur ;<\/p>\n

6. Efficacit\u00e9 insuffisante du chauffage.<\/p>\n

Remarque :<\/strong><\/p>\n

1. Apr\u00e8s avoir remplac\u00e9 l'huile de bo\u00eete de vitesses, d\u00e9marrez le moteur et laissez-le tourner au ralenti pendant 5 minutes, afin que l'huile puisse circuler dans le filtre et les conduites d'huile.<\/p>\n

2. Une fois que le moteur est \u00e0 l'arr\u00eat depuis 5 minutes, v\u00e9rifiez que le niveau d'huile de bo\u00eete de vitesses est correct ; sinon, faites l'appoint jusqu'au niveau sp\u00e9cifi\u00e9.<\/p>\n

3. Lors du remplacement de l'huile de bo\u00eete de vitesses, v\u00e9rifiez si l'huile usag\u00e9e contient des copeaux de m\u00e9taux lourds ou d'autres corps \u00e9trangers.<\/p>\n
