Im interested in learning how to diagnose and fix automotive A/C, for my personal vehicles. Im going to go to Harbor Freight and buy a set of gauges and a vac pump.
Vac Pump: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=92475
Will these do what i need to do? I know they arent the best quality, but im not going to be doing alot of vehicles with them.. maybe 3-4 vehicles.
Get the Mastercool book.
Cheap tools just don't do it for me. Several people have reported that the couplers on their cheap gauge set simply didn't fit on the car fittings. Spend a little more for a better gauge set.
The air-powered vacuum pump is useless. You really must use a mechanical pump for good results. Some local parts stores let you borrow one.
Even if you invest $400 in tools, compared to going to a garage it'll pay for itself after only a few simple jobs or one major repair.
I agree with MK378, get the Mastercool DIY Kit you will be much happier in the end.
I went to a pawn shop today to look for a better brand of gauges. They had 2 sets of JB gauge sets.
They were these ones: http://www.jbind.com/catalog/Page_12_JB_Industries_2007_catalog.pdf
On the gauges they didnt show R-134 on it... so will these gauges work?

So, we have a negative on the Harbor Freight air powered vacuum pump ?? This is hardly any consensus....
R12 Freon kits are becoming worthless; but they may be converted ???

The H-F pump claims 28.3" vacuum at sea level. Since there is 29.8" pressure at sea level, this means that the H-F pump can withdraw down to 1.5" Hg. That's 38,000 microns, and not enough to boil the water out.
try a search them or any Harbor Freight air powered vacuum pumps are JUNK get the kit tim posted and be done with it.
