Q: now that sounds a lot better 1 to 2 degrees is not worth my money as a home repair do it yourself person unless i can find a good suction pump used really cheap. when it 120 ambient and the inside of the car is in the 160 degree range 1 to 2 degrees will not be detected. 10 to 12 maybe but questionable. i have no problem with a professional using the best possible tools if they understand them and arent just using them for show. i am afraid most do not understand them though and might not even use them most of the time. i turned my ac on this morning. i installed a new compressor yesterday. the air was so much colder i turned the fan down to low and all of a sudden got smoke that smelled like wood burning coming out of the vents. i thought about it for a while then determined there must be something in the resistors that control the fan that got burned. sure enough it was packed with leaves. i did get a good look at the evaporator and could see that it was really packed with stuff also so off with the sides to see if i could wash it out. got the garden hose with a high pressure nosel on it and now it looks like it will pass some air. i have no doubt that it was almost 50 per cent restricted. just about ready to reassemble and see now much better it will be. so how do all these other non-condensables get into a closed system moisture i understand and metal parts for things breaking but if the system came from the factory with a good charge and then a seal started to leak i would not expect to have anymore non-condensables in the system after i replace the compressor than before i replaced it other than mybe some moisture from having the system opened. back to work i guess a retired person shouldnt use the word work so back to my fun project ron nathan w. collier wrote vacuum is not related to the temperature output on your typical auto ac at all. if you have moisure or non-condensables in your system it cannot possibly work as efficiently as it would if it were pulled down into a proper vacuum. please prove me wrong on this because if a super vacuum will get my ac 20 degrees cooler here in phx az i am for it. nobody said 20 degrees. if you pull a vacuum with a pressure gauge and a refrigerator compressor you might see a difference of 8-10 degrees. if you use a better vacuum source the difference may only be 1-2 degrees...but there will be a difference. we within the industry dont spend $300 for a decent 2 stage vacuum pump for the hell of it. we do it because as professionals we want to give you the best service possible and that means doing it right. if the cheaper alternatives were ok we would certainly use them i got dozens of compressors of all types and size that it ok off jobsites in equipment being replaced and same some money. the purpose of drawing a vacuum is to get the moisture out of a system that will cause corrosion and i real believe that is all. right or wrong and non-condensables which hinder cooling and can be fatal to compressors and metering devices. .

auburn hills mich. aug. 12 /prwire-firstcall/ -- in response to marketplace demands and evolving vehicle technology chrysler group has established a licensing program for its advanced synthetic automatic transmission fluid atf+4r. this program will allow atf+4 to be made available at retail outlets and through independent repair facilities for chrysler jeepr and dodge vehicle automatic transmissions beginning september 1 2005. a first in the industry chrysler group chose to work with the lubrizol corporation to develop a transmission fluid that sets new standards of performance in the marketplace and provides significant reduction in component wear. this technology also offers superior temperature performance providing consistent shift quality and exceptional friction modifying properties. the durability of atf+4 has been successfully proven through more than one million miles of testing in severe environments and an intensive chrysler group validation process. atf+4 will be implemented through issuance of licenses to major and independent oil companies. each blender and re-brander involved in the production and sale of atf+4 will be licensed facility accredited and periodically market-sampled to ensure consistent quality. its quality level will be closely monitored by the center for quality assurance through each step in the fluids progress from license through commercialization. the benefits of licensing our atf+4 product will allow the millions of chrysler group owners with vehicles still on the road to receive transmission fluid that is designed exactly for their vehicle said dennis florkowski chrysler group senior specialist/supervisor - chrysler fluids group. using atf+4 ensures a longer transmission life with regular servicing as described in the vehicle owners manual. atf+4 is approved for use in older transmissions and will be utilized in all future chrysler group vehicles. the previous mopar atf+3 formulation will be discontinued and atf+4 is recommended for all transmissions filled with atf+3. only certified atf+4 is recommended for service of chrysler group vehicles. the use of automatic transmission fluids other than atf+4 including those claiming to be like atf+4 could result in lower levels of performance and jeopardize transmission life. the atf+4 licensing program will be initiated in north america and subsequently expand worldwide. program license and administration will be managed by the center for quality assurance located in midland michigan. for more information concerning this program and licensing please contact rebecca cox director the center for quality assurance 989-496-2399 phone 989-496-3438 fax or clientservices@centerforqa.com . the atf+4 automatic transmission fluid formulation is exclusive to daimlerchrysler and atf+4r is a registered trademark of daimlerchrysler corporation. coasty .
