Water coolant is not replaced for a long time, the color of water in the reservoir will change from translucent green to brown and slightly turbid. What’s up? Her answers.

Engine coolant is not good used condition and began to cause rust in the coolant system. The solution must be drained and replaced with new ones. If allowed, the rust will spread to the cooling system and engine, the cost of the repairs made perforated bags.

Workshops are usually recommended engine coolant should be replaced every 2-3 years, although some are able to five years. Engine coolant is a mixture of water danethylene glycol. These chemicals are functioning so that coolant does not freeze, preventing the boiling water (boiling point reached 130 C) so as not to overheat quickly, and with other additives to prevent rust.

Engine coolant must also match the raw materials were highly diverse cooling systems, plus be able to transfer heat efficiently, prevent corrosion and provide lubrication to water pump baffle-insulator. When conditions are good, the color green.

Engine cooling system is built from a series of complex components and materials. Aluminum, cast iron, steel, stainless steel, copper, brass, rubber and plastics, is a constituent.

When two different types of metals contact with each other through the intermediary fluid will behave like battery acid, an electron-proton exchange. This is what triggers metal corrosion. Replacing the engine coolant on a regular basis to prevent excessive formation of acid in the engine cooling system while helping to reduce corrosion.

Ethylene glycol is a toxic chemical compounds. Just a little swallowed, can kill pets. Therefore suggested to replace the engine coolant in the workshop. Workshops will remove the old engine coolant, clean the engine cooling system and fill the new coolant.

In developed countries, many workshops have engine coolant recycling system. In this system, water is separated and channeled out, while its chemical compounds reprocessed.

Routine maintenance becomes an easy way to treat the cooling system. The simplest way, check the height of the liquid with a view of the tank. If less than the minimum limit, add a little water to exceed the minimum limit. Few months, attention radioator rubber cap. If damaged, replace it just take cheap investment for an expensive machine.

When a light gray or reddish brown, you take it easy because it means the engine is in good condition that fit the condition of the engine, ignition timing and engine settings.

When the end of the insulator, electrodes and spark plugs covered with black soot and combustion smooth and dry, you should immediately check the choke mechanism, the air filter and replace spark plugs if necessary. The possibility exists that does not fit with the spare parts. If ignored it will be wasteful fuel consumption, black smoke and difficult to start when engine cold.

Color slightly yellow edge insulation may appear light brown and green color usually indicates the possibility of gasoline or oil contaminated water or additives are less suitable. As a result, sluggish engine, slowly accelerates, breathing hard and explosive exhaust.

So be more frequent cleaning and caring for spark plugs. Since the spark plugs will support machine-groomed to work well. Clean the spark plug every 2500 km and have it replaced when it has covered 20 000 km

This means that drivers no longer have tired of stepping on the clutch to shift gears. On cars with manual transmission, to shift gears, the clutch must be pressed.

Another fact, of all the control systems should be operated driver’s car, the clutch is the most energy-consuming. In addition, the level of operation is also very high, especially when traffic jams or solid creep!

Easy out
Nevertheless, it turns out there are still many among us who still assume negative effect on the automatic transmission. It is also recognized by auto manufacturers. For example, if the strike, cars with automatic transmission can not be encouraged. If is often used in mountainous areas, brake quickly exhausted.

All the assumptions of the past. Now, more and more automatic transmission, the manufacturer provides the mechanics who have the ability to fix it faster if there is a problem. In fact, now there is also a general workshops that could deplete the entire automatic transmission fluid (ATF) in the transmission and then filled with a lubricant that really new and clean.

In the car now, especially the use of injection systems, when the battery is weak, then the machine will not start. Because the engine computer to get energy from the battery. Therefore, the position of manual and automatic transmissions the same!

Then, on the assumption that the automatic braking when the car drove lavishly in areas with many derivatives, ascertained, that the condition occurred because the driver was too relaxed, allowing the transmission to position “D” course. In fact, D is the highest gear.

Keep working
To reduce the workload of the brakes, the driver must use engine brake effect by using a lower gear. In this case, it could be “two” or if more steep and slippery, should be “L”. Same with low teeth, 3 or 2 on the manual transmission. As for acceleration, the driver should kick or step on the gas pedal down fast!

So, driving with automatic transmission that does not mean the hand does not work at all. At a certain field conditions, 3, 2, and L should be used. Hand still be active. Only the left foot is completely relaxed. No need to stampede the clutch at all. For example when the streets are declining or accelerated during the ascent!

In fact, the bad conditions, by releasing the brake pedal and transmission at the position “D”, the car can crawl without having to hit the brakes.

If you already taste the delicious automatic transmission, especially for those who drive themselves, often through a traffic jam, and have high mobility, they certainly will not want to go back to manual if you do not have to. In fact, they are willing to spend additional costs, both for the transmission of more expensive fuel consumption plus a little more than manual

For motorists who drive a car with a Multi Information Display (MID) device can easily monitor the use of fuel. Then, how about the MID figures show that wasteful fuel usage? Least wasteful fuel consumption also depends on driving style, technical factors other than mechanical course.

Here are some tips and tricks that need to be done to reduce fuel budget:

1. Do not stomping.
   Pedal must be stable and gradual. If you step on the gas pedal abruptly, auto fuel that will be sucked into the combustion chamber is also growing. Meanwhile, at that time was still low engine rpm. Consequently not all that fuel into the engine room fire. Which is called a waste. Because no fuel coming out in the form of energy, but go wasted through exhaust.
2. Discover the engine RPM.
   One way to make an efficient fuel consumption is to change gear (transmission) the right, which is when the engine reaches maximum torque (maximum moment).Gearshift when cars were in need of torque (thrust force), should be conducted with respect to information about the maximum moment (maximum torque) of each car (usually in units of kgm / rpm). Meanwhile, if the vehicle is moving (where the thrust is not needed), the most efficient when driving with the RPM between 2500 until 3500 and with the highest gear.

   For example, technical data on the manual written book Maximum torque: 200Nm/3750rpm. This means that the highest moment of 200Nm occurs at the time of rotating machines as much as 3750 per minute.

   In this example, means that we should make the shift gear when the figure shows the range of 3750 rpm. Figures can be viewed at RPM tachometer located on the dashboard of a car.

   Figures RPM on tachometer very important note. To streamline fuel consumption, while speeding down the road. Keep the engine speed at the maximum torque range. Because, that’s when fuel supply is in accordance with the output from the machine.

   One habit that is often overlooked driver is: do not immediately adjust the gears after lowering speed (deceleration). After running hard and then suddenly put the brakes suddenly, you should also pass the shift gear to a lower position.

3. Measure the HC and CO.
   Whether or not extravagant consumption of fuel is also determined by engine components. Machine components that have a lot of wear / damage can cause incomplete combustion processes.To detect it, check the exhaust emissions. If the examination results show the value of HC (hydrocarbon) and CO (carbon monoxide) is too high, this is a sign of combustion in combustion chamber is not perfect (lots of wasted fuel).
4. Expenses and Activator.
   Another factor that determines the fuel consumption is a load and drive (drive vehicles). Increasingly heavy burden to be transported, their consumption will also increase. The definition of driving include: couplings, bearings (wheel), coupling (propeller shaft), axles, and wheels.

   When these components worn or damaged, would cause loss of power generated by the engine to push the car running. Meanwhile, fuel consumption remains large. Related to the wheels, use of large tires and wheels, including the factors that affect fuel consumption.

Here, other tips are also noteworthy:

1. Habits out of the office lunch / evening, preferably reduced. Bring lunch / delivery seemed better.
2. If traveling, take the family / colleagues that one purpose / intention to go together in one car. For the same matters do not necessarily have to run two or three vehicles while with one unit will suffice.
3. Switch to public transport such as busways, railway, or metrominis.
4. When a traffic jam, while out of town, you should stop first. Changing other activities such as rest, eat, go to the bathroom, or fill the fuel to decompose congestion.
5. Drive gently. Reduce the frequency of braking. When facing a red light does not need to step on the gas, let the car slide because they must be stopped. Reduce the frequency stepping on the gas and brakes. This is the step energy disposal in vain.
6. When sliding or decreased, gear should not be positioned at neutral. Engine brake effect proved more economical fuel than stationary.
7. Turn on the AC as needed.
8. Ask workshop setting appropriate timing according to the type of fuel used. Ignition point too forward or backward resulting wasteful of fuel.
9. Clean the air filters (can be done by yourself) per 2500 km, or depending on conditions.
10. Do not heat the car for too long, maximum 2 minutes. Warming-up machine for 30 minutes, synonymous with traffic for 30 minutes as well.
11. Find the route / alternative road is not jammed, out a little with the current path is more save.

For the users of motor vehicles, the brake function is essential and not negotiable. Brakes are the most important safety component for the needs of motorists. For that, the condition of the brakes must always work perfectly, so that we avoid the incident “brake relieved” that eventually makes disastrous. Maintaining and improving the brakes are actually more modest than the engine or electrical system. There are several things that need to be taken by the driver to brake the car working properly:

1. Brake shoe or brake.
   To know the condition of the brake lining can be done by running the car at low speed while pressing the brake pedal and a half. Open the window and pay close attention friction voice. Both cars use the system disc brakes (disc) or drums will be issued a metal scraping sound when the brake has been exhausted. When that happens, replace the brake immediately with new products that manufacturers are encouraged to get maximum braking. Because, when the brake is still left plugged up, can cause abrasion on the wall above the disc or drum. If you already eroded, of course, costs will be far more expensive.
2. Tromol (drums).
   Currently there are many cars that use tromol or drum brake system. When rarely cleaned, much less often through a puddle of water, be easy on the brakes Tromol rusting. Immediately clean the rust that is on the dust cover (the dust cover) with fine sandpaper. Clean up all traces of rust remaining on the brake with the same sandpaper. Then coat of lubricant on the parts that have friction. Be careful when installing the brake circuit back or ask for your trust to do this workshop. When you are replacing it, try to walk slowly to reexamine the accuracy of the brake job.
3. Erosion of discs and drums.
   When abrasion disc or drum already occurred due to brake that has been discharged, you can bring your car to the turner. Just need to considered thoroughly to determine if it needs new turner returned or replaced. Measurement error on turning could be fatal, because the brakes may not work optimally.
4. Brake fluid.
   Brake fluid is like the heart of the braking system. For that volume of brake fluid in the master brake should always be on a level that is determined. To determine the appropriate amount of brake fluid, can be seen at the height of the control line in the brake fluid bottle.
5. Master brake.
   Braking system or not less than the maximum grip could result from the ineffectiveness of the master brake performance. Usually caused by brake fluid pressure in the brake master reduced. To restore these pressures can be achieved by rearranging the wind pressure in the brake master. For that, prepare to open the bolt wrenches his master cylinders. Before the bolts are opened, ask your partner to help shake up the brake pedal. When stepping repeatedly on the brake pedal under, ask your partner to hold some ground, while you loosen the master cylinder bolts. In this way the brake fluid will shine and you must immediately mengencangkannya bolt it back quickly. Ask your friend to repeat a foothold on the brake pedal. If the footing at the end was not too deep, then the improvement you make is correct.
6. Handbrake.
   Perform inspections on handbrake cable (handbrake). In serrations handbrake, you can moisten it with lubricating gel or grease (fat). While the cord itself can be smeared with lubricating oil. Check the length of the cord level through Handbrake lever. If the pull is too high, you can reduce it through bolts controller. Handbrake lever repeatedly for lubricants and lubricant gel evenly. When you pull the lever handbrake has been short, but still less good grip on the brake, it means that the brake was thirsty and asked to be replaced.
