This will prevent harm from occurring when the compressor begins to move or when it is first turned on. Following the completion of the repairs, the machine will remove all of the air and moisture from the system, allowing the refrigerant to be re-injected. Here is a step-by-step guide on how to add oil to a receiver dryer:1) Park your car on level ground and open the hood. The dryer is installed and I pulled vacuum already but I can take it off and add the PAG oil pretty easy. Point the laser at the back of the compressor, and if it exceeds 120-130C, there is likely an issue.

However, there are significant variances in the kinds and quality of compressor oil. . Your email address will not be published. Another item to look for is the intake manifold gaskets, which is a long shot. When changing a component, such as a compressor or an accumulator, it is usually a good idea to replenish the oil that was lost during the change. When gases are compressed, the gases become very hot. Step 2 Remove the cover from the back end of the compressor and hold it upside down to drain the old oil out of the machine. Furthermore, mixing R134a refrigerant oil with R12 oil is not a smart idea for a variety of reasons. If the compressor is completely dry (empty), you will need to execute the pre-lubrication procedure with the appropriate amount of oil, as described above. The AC compressor oil doesnt need changes and, in ideal conditions, lasts the lifetime of a car. This prevents the refrigerant from escaping into the atmosphere and allows it to be captured. Accumulator - 2oz. A video explaining how to use the AC injector. If you are not sure how to do this, consult a qualified technician. In an air conditioning system, oil is just as crucial as the refrigerant.

The new 134a rotary compressors are delivered with a complete system charge of PAGoil, which is exclusively compatible with the 134a refrigerant type. Some compressor kits, on the other hand, come pre-filled with lubrication, making the addition of additional oil superfluous. It then expands and cools as it flows through the evaporator. 8. This is due to the fact that it is compatible with both R-1234yf and R-134a. Following the recovery of refrigerant: When extracting refrigerant, some compressor oil will be combined with the refrigerant and will be taken from the refrigerant circuit with the refrigerant at the same time. It should be mentioned that evacuation must be carried out by trained experts using the appropriate evacuation machine and equipment. Low oil levels can cause compression failure and overfill often hurts the efficiency of the cooling cycle. The following is a list of some of the most popular oils on the market today: Range in price: $75-$85 for TSI. After that, you may have the device sucked to remove any air and moisture, either by returning it to a mechanic shop and using their recovery machine, or by using your own vacuum pump.

If the system has been flushed, the following is true: Original DENSO compressors, which are packaged with the appropriate quantity of oil, may be installed immediately after purchase. Not only does it provide a film on heat-sensitive components to reduce friction and wear, but also controls the amount of pressure that refrigerant gases need to move through them which creates waste without oil! Heres a chart that shows how much AC oil to add after flushing when you replace these components: Some compressor come with oil already installed and others come empty. Friendly format provided to inquire about automotive a/c systems. So the difference between 1-1/6 oz, 1-2/3 oz, and measuring what comes out is not something to worry too much about. Now, the problem with adding oil separately from the refrigerant is that its just as important not to add too much oil to the system as it is to have enough of it. Following the replacement of the component, you must recharge the system in order to preserve the seal and prevent leaks from forming again. Eautorepair.net redraws factory wiring diagrams in color and includes the component, splice and ground locations right in their diagrams.
