ADVICE

TIRES
  • What is the minimum legal depth of the tire tread?

    The minimum legal depth of the tire tread is 1.6 mm, but in this case the tire rendiment has lost a 90% of effectivity for road adhering

  • Should the tires be replaced regularly?

    Yes, at least once every 10,000 km in order to ensure a proportional distribution of the wear and a longer life cycle.

    To accomplish this, the first thing that must be considered is that tires that are installed on the same axle must be equal and the difference between their wear depth must not be greater than 5 mm.

SUSPENSION AND SHOCK ABSORBERS
  • What happens if you drive with shock absorbers that are in poor condition?

    Among other functions, the shock absorbers serve the important function of maintaining the tires in continuous contact with the road. A shock absorber in poor condition will result in a lower adherence to the road, instability and loss of control of the vehicle; thus, increasing the braking distance.

  • How often should shock absorbers be replaced?

    The degradation of shock absorbers depends in great measure on the fatigue they are subjected to (type of driving, type of surface it is driven on, etc); therefore, the...


EXHAUST SYSTEM
  • How often should the exhaust pipes be inspected?

    It is recommended that the exhaust pipes be inspected approximately every 20,000 Km. It is a quick task by which we can detect imminent failures and prevent further damage and higher costs.

    Components that are cracked, have holes or are corroded must be replaced.

  • How often are catalytic converters replaced?

    Under normal conditions catalytic converters are replaced every 80,000 to 100,000 km; however, an impact on the body of the converter may result in an internal catastrophic failure of the component; and therefore, it is recommended that the...


MAINTAINING YOUR VEHICLE IN THE WINTER
  • Tires

    Winter considerably increases the risk of accident as a result of the weather conditions. To prevent accidents, it is essential that the depth of the tire tread be inspected to ensure it is not less than 1.6 mm. The tire surface must be free of impacts, abnormal wear, cuts, etc.

    The tire pressure is also a factor that affects driving safety. Ensure that the pressure is correct. A lower pressure than normal closes the grooves of the tread design, reduces the evacuation of water and increases the possibility of hydroplaning as well as degrades it prematurely.

BRAKES
  • Do the forward wheel brake pads wear at the same rate as the rear wheel brake pads?

    No; when brakes are applied, most of the weight of the vehicle falls on the wheels installed on the front axle (the rear axle tends to be raised) and as a consequence of this, the greater braking action is exerted on the wheels installed on the front axle and consequently, the wear of these tires is more severe and occurs faster.

  • How often should the brake pads be replaced?

    The duration of the brake pads depends on factors such as the hardness of the pad material, how the brakes are used, the condition of the...


ENGINE OIL
  • Can two different oils be mixed?

    All oils can be mixed together regardless of if they are for petrol or diesel, mineral or synthetic but doing so will lower the quality of the highest grade and the final product does not usually average the characteristics of both; therefore, mixing different types of oils is not recommended unless their characteristics are very similar.

  • What is the difference between mineral and synthetic oil?

    A mineral oil is formed directly by distilling petroleum and adding components to improve its performance.

    The bases of a synthetic oil are physically and chemically...


FILTERS
  • Do I have to replace the oil filter when changing the oil?

    The filter must be replaced as indicated by the manufacturer.

    In general, if the oil change intervals are long or the engine is operating in severe conditions, we must replace the filter every time the oil is changed; otherwise, it may be replaced every other oil change.

  • How often should air filters be replaced?

    It is recommended that oil filters be replaced once a year or every 20,000 Km. (Unless otherwise specified by the manufacturer).

    When driving in dusty environments, the replacement interval will obviously be reduced.

  • Why must the...


STEERING
  • What is indicative of an improper steering alignment?

    The vehicle drifts to one side when driving in a straight line.

    The steering is abnormally stiff.

    The tires wear irregularly at the inner or outer edges.


TIMING BELT
  • When should the timing belt be replaced?

    The replacement intervals for the timing belt depends on each vehicle and may vary from one to another between 40,000 and 120,000 Km.

    In any case, it is very important to follow the intervals stipulated by the manufacturer in order to prevent damaging the engine.


SPARK PLUGS
  • What is the thermal grade of a spark plug?

    The thermal grade of a spark plug indicates the capacity of the sparkplug to evacuate the heat that accumulates inside it during the engine’s operation. A spark plug will be “cold” if it is capable of evacuating a large amount of heat and by the contrary, it will be hot if its evacuation capacity is small. An engine that generates high temperatures in its combustion chamber will require a cold spark plug and vice versa.

  • Why is the thermal grade of the spark plug important?

    A spark plug must operate between two temperature intervals. If its operating...


BATTERY
  • What is a maintenance free battery?

    The battery accumulators are manufactured using lead along with small additions of other materials. The difference between maintenance free, low maintenance and conventional batteries is the material that is combined with lead. Conventional batteries have between 5 and 6% of antimony added to the lead; the low maintenance types have between 2 and 3.5% and the maintenance free batteries use calcium and lead or calcium and selenium.

    Batteries with antimony accept current after reaching full charge. This overcharging causes water to evaporate from the...


ANTI-FREEZE
  • What does cooling fluid consist of?

    Cooling fluid is made up of basically water and ethylene glycol (alcohol that lowers the freezing point of the liquid) in addition to other specific additives.

  • What purposes does cooling fluid serve?

    In addition to evacuating the heat generated by the engine, the cooling fluid raises the boiling point of water by incorporating anti-freeze, it decreases the freezing point and protects the engine against corrosion of the aluminium, bronze, copper, welds, steel and cast iron and prevents deposits and sludge from forming.

  • What happens if I don’t replace the...
