Know Your Car Air Circulation Device

Know your circulation device AC and damage anything that could happen on this device
When your car's air conditioner works already weakened alias no longer blowing cold air to the maximum, not necessarily the cause of freon to be filled again.  

Damage to one of these devices can cause the circulation of air conditioning is not cold anymore and freon run out quickly. For that recognize some air circulation device and any damage that may occur in these devices that influence your car air conditioner work: 

1. Evaporator

• Function: change the liquid into gas freon cool. In this device the liquid freon cooling process occurs. 
• Damage: leak due to dirt that accumulates causing corrosion / loss. 

2. The thermostat

• Function: to supply electrical power to the compressor automatically. The sensor will detect the temperature on the thermostat in the evaporator suits. If the thermostat is damaged then the evaporator could freeze because electric circuit breaker malfunction. 
• Damage: marked by smoke from the AC grid and the presence of water droplets like dew dripping from the evaporator.

3. Dryer

• Function: a place to store temporary freon when thawed by then supplied to the condenser to the evaporator. Another function is to filter impurities in the air circulation system. 
• Damage: clogged dryer by a pile of dirt carried by the condenser. When the dryer is broken then the spare air becomes unstable and changeable.

4. Expansion Valve

• Functions: spray liquid Freon from the dyer to the evaporator temperature and low pressure. 
• Damage: expansion valves can be damaged if the dryer is also defective because it brings dirt to come in so that the damage can spread to the evaporator to participate exposed dirt.

5. Condenser

• Function: Change the Freon into the high-pressure fluid and high temperature. 
• Damage: Can a leak, dust dirt and mud can damage components.

6. Compressor

• Function: Pressing the liquid Freon into the condenser. 
• Damage: Leaking seals, a weak magnetic coupling, decreased compressor oil. If any damage is usually accompanied by signs of the emergence of noise when the air conditioner in a condition on.

How to Care and Inspection of Car Engine Cooling System

 Some things that can be done for maintenance and inspection of the engine cooling system to prevent overheating engine or high temperatures.

1. Check the condition of the radiator and cooling system leak

Some parts radiator that needs to check is the upper tank and a lower tank, especially the use of plastic radiator tank to the upper and lower tanks. Because at a certain mileage kilometer upper tank and a lower tank made of plastic will be brittle and cracked causing water leaks radiator. Upper tank or radiator top section will first undergo damage due directly receive hot water from the engine. By using the radiator or radiator tester cup tester. By way of providing a higher pressure than the pressure relief valve radiator cap, radiator cap has a pressure of 1.1 bar generally or 0.9 bar. If a leak is found or dripping water treatment can be done at the site of the leak.


2. Checking Conditions Close radiator

There radiator cap rubbers if the rubber is damaged or has hardened can cause engine cooling water does not go through the radiator out of the reservoir tube. Examination of the radiator cap can also be done by using a cup radiator pressure tester to determine radiator relief valve begins to open, if not as stated on the radiator cap better soon replace the radiator cap.


3. Use Radiator Coolant

Water when heated tend to react with the metal and make the metal solution therefore if the radiator is not given radiator coolant water often has his usual yellowish color yellow will stick in the radiator. Impure water often contains metal in it that can cause the crust and eventually clog the radiator which in turn makes the engine overheating.
Water has a low evaporation point only 100 C while the temperature of the machine can be up to 140 C so if we use the water to fill the radiator, the water in the radiator will be quickly reduced. So the radiator coolant is recommended for your car radiator.


4. Check the condition of Slang and Its Radiator Clamps Radiator Slang

Conditions where the radiator hose is time in lieu is when the hose has started to harden, and when in the press by hand is no longer pliable. Usually a sound alert when the radiator hose on the tap.


5. Check Blowing or Wind Speed ​​Radiator Fan Radiator and Its Surface Cleanliness

Modern machines with the motor cooling fan, motor cooling fan or radiator fan will run when the temperature reached wickedness. Impurities such as dust, leaves or bent fins will reduce the ability to dissipate heat radiator, but it also adds to the load on the motor cooling fan with his mark up the electrical current flowing to the motor cooling fan "when using the motor cooling fan." Conditions Motor Cooling Fan motors also affects wind speed cooling fan or radiator fan to remove heat radiator.

6. Check the height of engine oil through oil Stick

Functions in addition to the engine oil to lubricate the engine parts that rub well to cool the engine cooling system apart, it is important to keep the engine oil in sufficient quantities.


7. Check the condition of V-Belt Water Pump Yang Play or Water Pump

Examination of the condition of v-belt to prevent the v-belt broke because v-belt that is already visible cracks should be prone to break and must be replaced to prevent a break up in the middle of the road.

How it Works Close Radiator?

Function and How it Works Radiator cap - Close Radiator serves to maintain the pressure in the cooling system of the engine. And cooling system in a vehicle is an important component to maintain the temperature of the engine to prevent overheating.

Radiator cap not only serves to cover the radiator as we closed the water bottle when it's closed over the issue because water does not come out.

cooling water circulation

Inside the vehicle cooling system, when temperatures rise automatically the cooling water temperature rises and the pressure in the system goes up. There is a mechanism in order to cover up his radiator temperature and pressure do not cause the radiator or radiator hose burst.

relief valve works

In the picture above, the relief valve is driven by the water pressure inside the radiator when the pressure exceeds the radiator pressure relief valve spring, the amount of pressure is usually written on the radiator cap. Furthermore, the water flows into the reservoir or water supply tube radiator.

vacuum valve works

When the working temperature of the radiator water temperature sensor (water temperature sensor) is reached, the motor cooling fan works, gusts of wind cause the temperature and the pressure drops, there is a vacuum in the cooling system, vacuum valve opens and the water from the tube back into the radiator or reservoir.

Vacuum valve serves also to bleding water in the cooling system, when there is still air trapped in the system.

Tip water filling the radiator:
If the cooling system at drain out and replaced with new radiator water, add water to the radiator until it is full, do not install the radiator cap first, but run the engine for a while, the water will go down because the radiator fill the empty space in the engine Circulate the water pump (water pump), add more water to the radiator until it is full again, then close his radiator. Do not forget to fill up the radiator water tube (reservoir).

If the above is not done, for some type of car can cause over heating. What do you think why? Please give coment below.

A few things to note from the radiator cap:

• the condition of the rubber relief valve, relief valve rubber could be damaged by the use of unsuitable radiator coolant, radiator coolant usage that does not fit can damage rubber thermostat. 
• vacuum valve condition 
• spring-loaded pressure relief valve that can be checked using the radiator cup tester
