The name for such a car is Nissan Tiida. The evaporator is one of the main components of an auto air conditioner system. Many of problems may occur with them. Many car owners and DIY people prefer to work on and repair their own vehicles to save money and to get peace of mind to have good repair. Problems with the A/C parts range from mild to severe. It is important for users to know how condensers and evaporators work and which kind of problem the posses, different brands and their features, the problems that occur with them, and how to fix the problems with little effort and money having cost effective solution. The evaporator is a heat exchange system in a car A/C system. They are usually made of aluminum and a kind of small radiators. A series of internal tubes with attached fins make up the component. Air travels through the fins, and the internal tubes carry moving refrigerant or gas. Hot air from the vehicle passes through the evaporator, and the refrigerant absorbs the heat from that hot air. Humidity condenses on the cool surface and drips out of a tube outside of the car. For this purpose car manufacturers create a special vent close to the firewall. The refrigerant then moves on to the condenser and taking the heat of the hot air and radiate in the atmosphere on condenser part. Like evaporators condensers look like small radiators. However, instead of absorbing heat they release the heat in the atmosphere. They release the heated refrigerant absorbed while flowing through the evaporator. The refrigerant enters the condenser as a high-pressure vapor. There the pressure of the refrigerant releases all of a sudden on a component known as expansion valve. The expansion valve actually controls the flow and pressure of the refrigerant according to cooling needs and requirements. As it flows through the condenser and cools it turns back into a cooler high-pressure liquid. Various manufacturers of evaporators and condensers are there on the market. Each brand has unique features made for specific models and makes of vehicles. Users may review the features of each brand to find the replacement part that is most compatible with a certain car. The best replacement part could be the OEM or the exact replica of the OEM. A few manufacturers are Toyota, Nissan, Evero Evaporator, Spectra condenser, UAC Evaporator, Mazda condenser, Chevy, Chevrolet condensers and many more. Every company that produces condensers and evaporators are trying to meet quality auto standards. The companies make the parts from a variety of materials that provide quality performance and less instances of leakage. People may review the features to find the part that matches to their particular vehicle. There are many possible problems can occur with condensers and evaporator. Sometimes problems with condensers and evaporators arise. Do it yourself mechanics benefit from knowing the sign of common mishaps so they can repair them before further damage occurs. Different types of diagnostic tests help users find the problem and fix it. Minor or major restriction, faulty cooling fans or fan clutch, or poor airflow across the condenser prevent refrigerant from cooling down properly. The resulting warmer air or extensive back-pressure often causes damage to the compressor. To detect this problem, users may check the temperature of the condenser's inlet and outlet with the A/C on the highest setting and all windows and doors open. 21-41 degree temperature difference between the inlet and outlet is a normal value. Less than 21 degrees indicates and airflow problem and greater than 41 indicates a restriction problem. Each problem is preventable with regular flushing and cleaning of the air conditioner system. R11 refrigerant is used to clean the air conditioner system. If too much damage exists, the user must replace the entire condenser. Problems with an evaporator are indicated when it produces less air than normal. A frozen evaporator forces air around the outside instead of through the cooling fins. Improper metering from the Freon to the evaporator is one cause of the problem. A broken or absent cabin filter or blower motor is sometimes the culprit of a clogged evaporator. Most of the time people are removing cabin air filters to get more air flow and the result is eventually a clogged and dusty evaporator. Flushing and cleaning the evaporator prevents and often fixes all problems. However, users must replace severely damaged or worn out evaporators. Evaporators are most of the time leaking. The leakage is sometime due to rubbing and sometimes due to material fatigue. Whereas the oil remains on the same surface of the evaporator. So that residue oil is telling the story of destruction. You can buy one from Tashleh or junk yard car whose evaporator is good in condition.
