We are happy to send you the 6th INFO MANEJO's issue. This time you'll learn the way to adjust your car mirrors correctly, how to prevent the engine from overheating and why it's necessary to analyze accidents.

   How we adjust car mirrors?
When we drive, we just see in front of us, that is why car mirrors are important for driving safely. They allows us to see what's happening behind us and on the sides.

Some tips on how to adjust them:

+ We should regulate their position after we place ourselves in front of the steering wheel. They should let us see behind the best we can.

+ It's advisable to place the rear-view mirror framing the rear window.

+ On the side mirrors we should see very little of the side of the vehicle.

+ It's not prudent to change the mirrors original curve because it distorts the distances, causing dangerous situations.

+ It's also important to know that there are always non reflected areas, "blind zones" (see drawing). Thus, we should turn our heads to the sides to check these zones while we drive. Also, we should turn our heads to see rear window while we park to help us complete our line of sight.

+ When we decide to take the road up again or to turn in U in open roads, we must never trust only on the mirror reflections. The blind zones might not let us see if somebody is coming behind us.

+ If driving a heavy vehicles, when going in reverse, it's essential to use all mirrors because the load doesn't allow to see behind if we turn our head.

   How to prevent the engine from overheating?
If the pilot light turns on or the engine's temperature indicator is on the red danger zone, we can guess that the high temperature is caused by the lack of cooling liquid inside the circuit. But, when we check at the recovery recipient we notice it has some liquid. It might seem paradoxical; on the contrary, what happens is that in these cases the defect is caused by a small leak somewhere in the circuit that slowly empties the cooling liquid from the engine, and the recovery recipient stays in the same level.

Why does this occur?

This is a pressurized circuit, so when the engine's water heats, it expands and increases its pressure. This physical effect takes water into the recovery recipient, which absorbs it, and when the water temperature decreases, pressure also decreases and it inverts the process, allowing the needed cooling liquid from the tank to the engine, balancing automatically the circuit through temperature and pressure differences. If a leak appears in the circuit, this automatic recovery principle does not work because pressure also leaks.


How can we know this happens?

To be sure that the circuit is not working correctly, it's advisable to check that there are no cooling liquid stains on the floor where we park the vehicle. If this occurs, it means that the cooling liquid is leaking. It's easy to distinguish this kind of liquid by its colour: honey, fluorescent green, blue, etc. As soon as we see these stains, we should go to the mechanic so he checks and repairs the engine cooling circuit.

   Accidents study
Accidents are events in which people's lives are at risk. They represent loss of money and are regrettable, but they are also knowledge sources that help to understand how to prevent them.

When an accident occurs, it should be managed as the other vehicle system factors, in order to learn as much as possible. For this, a sequence of steps should be followed:

1-Unconnected specialists present an unbiased report. The company should aid them with the necessary elements to perform:

- The analysis of the accident scene
- The examination of the vehicles involved
- The study of the documents
(interviews, tachograph data, trip management, medical reports, etc.)

2- The specialists' report is analyzed and studied, seeking for the accident's cause, paying attention not only to the technical causes, but also to the deeper causes by using any known methodology (cause-effect analysis, 5 W, etc.). If there are vehicle management policies and procedures, such as trip management and maintenance rules, the first step is to check if they are complied and if they are valid. Bear in mind that this kind of analysis requires a process of polishing and testing, including various cycles of meetings and working.

3- Knowing the causes, it should be checked if they involve any kind of procedure error or potential risk not taken previously into consideration, following, if necessary, a subsequent improvement: trainings, audits, standard revisions, etc.

4- Spread the accident analysis in a simple and efficient way so it turns into common working capital in vehicle fleet areas. This is actually where learning takes place. Effective communication using diagrams, images and animations is essential for the unspecialized personnel to comprehend what happened and its causes.

The classified and measurable indices plus the background of events are valuable tools to manage accidents in a long term period.
