Where does someone find a vacuum pump?

chrisvill54 says:

This is not a diy job, look at all the stuff you need. Vacuum pump,
refrigerant recycle machine. Must of us do not have these things on hand,
they are not common tools. Oh and you also need a special scale to refill
the system? I’m sure some will try it but most will be discouraged from all
the stuff you need.

chrisvill54 says:

But thanks Scotty I now I know where my leak is coming from there is oily
stuff from one of the lines so that’s where my leak is coming from.

The Headless Horseman says:

I have a fast a/c leak, in my 94 k1500 suburban. I tried stop leak but it
only made it worse. I put the uv dye in and it was all over my interior, on
the seats and door panels. What do you think is the issue? Thanks

Are you high of just too much coffee?

Vipul Mehan says:

Hi Scotty, the line was open for a year I would say, and my mechanic
vacuumed it for about 10 mins using those powerful snap on ac kits, it
reached 22Hg and refilled with 134a and it works fine if I turn the ac on.
What do you suggest at this point? 

Gilbert Arciniega says:

Are the A/C compressors from Ebay OK? Can I trust a manufactured compressor
there? Because I seen them on average of $140 for one. For an 01 Civic

Kuldeep Rawat says:

How mach a/c oil

Vipul Mehan says:

Ac drier was not changed. It is now winter and I will not be needing my ac
until the summer. Would it be wise to not turn my ac on and before the
summer to buy a new drier and replace it? I hope my system will not get
damaged by turning it on while there may be moisture in there.


Brandon Wittmer says:

Anyone who wants to do this should know your local AutoZone carrys the vac
and manifolds on there loaner tools list

Gilbert Arciniega says:

How much does a shop charge to remove all the freon? Because I know it’s
illegal to just let it out to the air. Is it a recovery or evacuating?

Reason I ask is because the compressor is gone on my 01 civic. And want to
replace it. My A/C did not leak, but it just abruptly stopped working.
(noisey compressor)

Vipul Mehan says:

Is it ok to run the vacuum pump for 10 minutes by using a snap-on
commercial pump? The pump was stopped at about 22Hg. 

Vipul Mehan says:

Thanks Scotty! 

Mike Blake says:

Thanks Scotty.

Thanks Scotty!

you da man Scott!!

rpn000rpnca says:

Scotty, I have a digital kitchen scale. Can I use it to measure
refrigerant by subtracting before and after weights?

John B says:

Scotty, great video. Another question though. I have a 2011 Buick
Enclave. The Buick/GM Dealer has checked for leaks 3 times and charged
freon testing with dye on each occasion. Quite frankly for this an some
other problems, the car has been back to Buick 7 times in 6
weeks!….ouch. The claim is that they are not seeing any leaks from the
system. (Obviously if it is low, it is leaking out.) I currently get a
hissing noise which ultimately goes away somewhat and some cool air when
the vehicle is in motion. When the vehicle is stopped…nothing but warm
air.

So..
1) Where else could freon be leaving the system from?
2) Is there anywhere I should be pressing the dealer “to look”.

Jeremy Larry says:

Scotty I dont know what I would do without the wealth of knowledge you
given through your great videos.

hi scotty, i have a 2003 matrix that a/c blows cold air but barely even on
high setting no.4.. thanks tholitz

TheEgg185 says:

i suspect there is no refrigerant at all in my system. but to test it with
a gauge, does the ac have to be running? or do you just check the gauge
with the ac off. i would imagine that running the ac at all with no
refrigerant would be bad, right? also what about injecting uv dye to find
the leak. can you inject it into a system with 0 refrigerant and run it?

Tigrazzo says:

Scotty, you are the coolest mechanic I’ve ever seen, thanks for all the
knowledge you share with us.

MegaCobra011 says:

SMART GUY BUT ACTS LIKE HE JUST ESCAPE FROM A MENTAL HEALTH FACILITY.

Scotty Kilmer says:

places like harbor freight sell the tools at low prices. Realize most
mechanics charge 100 bucks an hour and that buys a LOT of tools.

hamzauy says:

And would you please make a small video about that
