DIY A/C Recharge kit for 2002 Sonata GLS
All,
Have any of you done a recharge on your A/C unit? Mine seem to have run out and needs to be charged. If you've done it, do you recommend using one of the kits available at an auto-part store (Murray's, AutoZone, etc.) or have it done by a pro? I've been told the kits are pretty easy to use so I would like to learn to do it myself. Thanks for any help. - Thee Chicago Wolf |

To do it right, you need to start from scratch, which means you need a good
set of gauges and know how to use them. You also need a vacuum pump to hook up to the system, which will cost you about $400 or so. You really do need to know the procedure so get a shop manual for the car. If you do it wrong, and open up the high pressure side to the can of freon, you're dead! It's really not that hard but you just need to know the steps and precautions.

Sorry, but you don't need a vacuum pump. If you have good gauges, hooked up to the right ports, know the ambient air temp., and how much charge the system is supposed to have, you can fill the system properly without a problem. Eric |

Although gauges can cost hundreds of dollars, you can usually find someone that will let you borrow a set, and then you can just use a can of R-134a from an auto supply. Eric |

You might not need a vacuum pump for your AC service, but I sure do. Of course, I like my AC cold and my pumps happy and long lasting. Iced up orifice tubes suck. JS |
