ok this guy did ok in what he did but he didnt do everythinghe should of done pressurized the system with nitrogen and left it for 24 hrs in standing pressure to see if it has a leak, he should of conected both hoses, the hi and low, the should of vaccumed both sides after seeing that there are no leaks, put it in a vacumm for an hr or more and use a micron guage. he shhould of charged the liquid in first and so on but he shows u an idea, i wouldnt let him touch my car lol just sayin

[aman450r]

THATS A VERY NOISY PUMP LOL the rugular good JB pumps are quiet but there used in AC units in residential and commercial

[aegisforex]

I do my own maintenance, but you overpaid for that pump. Not everything on eBay is a good deal.

[aegisforex]

For what you paid for the vacuum pump, you could have paid a mechanic to vac and charge it.

[BiteDoctor]

@aegisforex  you just dont get it. i bet you pay someone to change your air filter too.

moisture is the number 1 enemy of ac systems. evac for 30 mins or so, maintain the vacuum. DO NOT crack open the valves like was done in the video here...you are letting in outside air, which INCLUDES moisture..... and, never ever open up the HIGH side port, ever, when servicing like this. Otherwise, my only other suggestion is really to get an good grasp on what the manifold gauges are telling you...high and low side. Very dangerous. Lucky it seems to have worked, but kudos for posting....

[reluctorvalve]

A couple of things, here....not that i'm a goo roo or anything, but was a prof mechanic in AZ for a number of years, where it's HOT!

-first, the entire 'purpose' of using a vacuum pump is to pull 'negative pressure' (oxy moron, I know)...but the real purpose of that is that during those many minutes of pulling vacuum, the molecules of air in your system are being broken down, and the moisture is being evacuated OUT of the system, so maintaining a vacuum is super important.

[mex2texzz]

HI i was wanting to know if you could answer me a question ,i have just bought ,a "diavia" air con kit ,for my1991 vw jetta ,it was a factory option back in the day ,as this kit is brand new old stock that was meant to be filled with the now defunct r12 ,is there anything i would need to do to this to make it compatible with the r134 ,up until a couple of days ago ,i knew nothing about air con,so any help you could give me would be much appreciated ,thanks ....kevin

[dans289]

looks like you have your yellow line on backwards

[jeujiair]

Man you haven't got a clue whats going on here.

I cant believe you guys can buy R134a in cans,.

This is a typical example of why we have to be licensed in OZ.

Turn the yellow hose around the right way and remove the black cap of the vac pump to start with.

[JorgeGpeHdz]

Hello . Is important to remove the vacuum pump cap , that's why so noisy

[charliekae1]

my god shops still selling r 134a to untrained personell

[tippman2k01]

@charliekae1

[jityr2]

Why is YouTube loading so slow lately. Pissin' me off.

[hbjesse]

what a fuck.. you making me so confused.. seems you have no clue of what you're doing...

[SpeedDemon07]

Those temperatures on the gauge are used as a reference to tell you how how much psi you should fill it up to. so if it is 80 degrees outside you would fill it up to the corresponding psi.

[01mustang05]

I am learning all this auto a/c stuff and this is the 1st time I am confused. I will watch the rest of your vids tho 2 see if i can figure out what u are doing.

30 inches of Mercury is a perfect vacuum. It has never been accomplished so 29.99 or 29.95 is often used to be the best vacuum possible

[killerclown1740]

did you run the vacuum on the high side
