- Maybe your motorcycle exhaust (especially for 4 stroke) or discordant sound louder so not pleasant to hear. That’s a sign from a thin foam damping and is valid for racing kanlpot daily.

“Daily racing exhaust on the market is usually already equipped with silencers silencer inside it. Just like the daily motor, just the density of fiber material type silencer and baseball know for sure. Hence, there is a racing exhaust melodious voice, ngebas, and too shrill,” explained Harry Noprian , mechanical Harry Motor HMTC in Pondok Kelapa, East Jakarta.

Foam is commonly called glass wool silencer. This foam is to muffle the sound. Noise level depends on the thickness, density, and durability. According to Harry, fiber silencer was the yellow and white with a tag of Rp 3,000 to Rp 5,000 per pack.

Only, installation necessary prudence. The reason is, fragments from the fiber powder made uncomfortable, especially when tersenuh hands, or body itching immediately. In addition, we may inadvertently packed if powder inhaled lung.

In addition, there are also made of glass fiber material. But according Kunto Hayadi, mechanical HKR Custom, type of material it is inconvenient. Only, more durable and more expensive than glass wool. This material is also more heat resistant, although the powders easily wasted if the machine is often digeber.

Other options, there steelwool or metal fibers lumpy model. Glance looks like a dishwasher appliance from stainless steel fiber material. Indeed, the price of USD 35 000 more expensive when compared with glass wool.

The advantages of this metal fiber material according to Kunto exist in the material that is not easily burned or thrown out. Tripling the remaining life of the glass wool. The disadvantage, because it was too long in the silencers, this section will likely appear rust.

If you do not want to be bothered, Kunto recommend disposable silencer from kevlar carbon fiber material that has been neatly and tightly woven. This material is not flammable and Gap meetings and able to withstand heat. Cuma, more expensive.

Almost all modern car engines use a water cooling system to maintain warmer temperatures. So, the water into “blood” which channels the heat from generating sources to the final disposal.

The problem, no air bubbles seldom appear in the path of cooling water. Can disrupt the air entering the pressure in the system and ultimately disrupt the engine cooling water task. Greater risk because of overheated engines  position in the cars are now more tightly.

Air can enter the radiator cap when opened and closed. That air exists between surface water and radiator cap. In addition, air may also exist because the radiator cap condition was not good.

At the radiator cap there is a functioning valve air flow from the reservoir tank when the heat and sucking water from the reservoir to the radiator (when cold).

How to expel the trapped air? Follow the steps below

1. Make sure the temperature of the engine in cold conditions.
2. Open the radiator cap. Turn on the machine (so the water circulates). After that, enter the water to the mouth of the radiator, and stop if it is full.
3. Cover again with a perfect radiator.
4. After that, unscrew the air dump. Waster closed position every different car brands. The location can be seen in the vehicle owner manuals.
5. Notice the water coming out of the valve. If there is scum, then it indicates there is still air in the cooling channels. That means you have to keep doing this process until that comes out is water without foam.
6. Check the amount of water in the tube resevoir reserves. If not, add up to the limit.

Interior car needs to get regular maintenance. One of the biggest portion is the seat. There are already covered, either by using a leather or synthetic, which must both types of material is easily cleaned.
Moreover, using fabric materials. According to Edy, Vertue Concept seat maker in North Jakarta, this type of dirty quickly because of its easy to absorb. And so the source of disease because of the dust collector and humid.

Below are tips for cleaning upholstery layers of synthetic material.

* Have a small bucket of warm water, baby soap or other gentle soap. Then, chamois and a clean dry cloth.
* To clean the stain, mix warm water with soap or mild soapy baby earlier. So on, wipe with a chamois that has been dipped.
* Rub the stain to disappear gradually, as he continued wiping it dry.
* If the stain does not go away, cleaning may dijabani with a special cleaner for synthetic leather.
* For routine maintenance, should do at least once every two weeks.

There are no bad roads in Jakarta or other big cities in Indonesia. When you’re driving, dealing with such conditions, must be very miserable because there was no Air Conditioning (AC).

Until air conditioning was not functioning due to negligence of the owner can perform maintenance. Age can also use components or high frequency of usage. Much more heavily, “many car owners who lay on the AC. Therefore, when performing many of the baseball understand about the service,” explained Ferdian, air conditioner repair shop owner in Arteries Kedoya Panca Jaya, West Jakarta.

Here are some gejkala that occurred in the AC car

Less cold
The trigger came from the compressor. According to Chandra from the workshops of AC in Jatiwaringin Cottage, East Jakarta, the magnetic clutch is worn or broken bobbin magnet there. As a result, the freon compressor drain obstructed.

Other causes, there is a freon leak in the evaporator mengnakibatkan wasted. Chandra advice, must change if the new resistant welded only briefly.

Less savory odors
Cause, the interior condition of passenger carrying dirty due to food habits. The smell of leftovers can be stuck to the seats, door trim or carpet. involved has a share smoking habits contribute not tasty aroma.

A strange sound when switched on
Origin of the compressor noise is usually problematic. Still according to Chandra, bearing in the compressor is worn or broken compressor make noise. Others, coming from the blower. For some brands of cars, the position of these components exist in the glove box. If a drawer full of denngan books or objects and then sucked lightly, immediately making a sound.

Freon often less
This condition is caused by a leak in the hose or evaporator, so that freon is wasted. “Generally freoan reduced after the use of the above two years,” said Chandra. Cost to drain and recharge the freon between Rp100-Rp200 thousand. Instead, do check and clean the compressor every 2000-5000 km
