Charging A/C - 1997 Dodge Caravan
Clutch died on thsi van and I installed a used compressor. System
needed to be charged and I took it to a local garage thinking I'd be there awhile. 15 minutes later I went into the service bay to check on the progress and I saw the mechanic with one of the small can's hooked to the van, just finishing..... I don't think he used his A/C machine, I think he just dumped 2 small cans into it. Since the system was empty how did he get the compressor to kick in? Jump the pressure switch? And will the r134 just flow in to the empty system. Thought when you did a vaccum to test and all ok the vaccum will suck the 134a in. Long winded, sorry, and thanks in advance |

Judging by your initial question, I'd suggest you leave > it to a pro for safety's sake. > He DID, he "took it to a local garage" My experience is that 90% of the service places out there that claim to do A/C work do crappy jobs like this. Hell, any garage that buys R134a in the small cans instead of in a large container that is sitting on a scale all the time, probably isn't doing enough A/C work to be considered a pro when it comes to A/C A/C work is no more dangerous than pushing a car off a jackstand onto your foot. In fact it's probably safer - I think you would be hard pressed to find an example of someone dying as a result of improper service on A/C - but there's lots of people maimed and killed because of cars falling on them because they used a tire changing jack to hold the car up while they went crawling under it. The tools for servicing A/C are no more expensive than paying someone to do it, (except for a refrigerant reclamation machine, and you should be able to go to any garage that claims to do A/C work and have them take your freon out of your car) and if you know what your doing and go slowly and carefully you will be sure to do a better job than every other A/C shop in the city, save the very top shops.

Ted, I also have a Caravan 1995 that has R134a in it. It has small
leaks in the system that would cost me a bundle to fix, so I have been getting it charged yearly. Every summer I have to charge it myself. Do you know of some instructions that would help me charge my own? Here is a link I found on operating the manifold http://www.robinair.com/opmans/118571.pdf Mike |

I read about some Kool-Stop or something that seals leaks after you put
it in. What do you think about that stuff? I think to fix my leaks you have to remove the dash. |
