Scotty, two questions: It does not appear you hook up the high side hose when pulling a vacuum. Is that correct and if you do (connect it), do you open the valve to that side? Also, I assume when you pull the vacuum pump off (you don't show this), you close the valves and then remove the pump? Thanks, this is very helpful!!
@blackmarkiv I used to hook up the high side too, but modern cars are so cheaply made, many don't have high side hoses, and those that do are so cheaply made they often leak after you hook a gauge up to em, so I keep hands off. The rest of your stuff is fine.
i it legal fr people without refrigerant licence to own r34a? im pretty sure it isnt, and dude dont let anyone catch you bleeding the hose like that because that lets refrigerant into the atmosphere and thats a $10,000 fine.
@justins462 depends where you are. Here in Texas, anyone can buy 134a at an auto parts store. And that tiny bleeding isn't going to do much. But if you are in a more restrictive area, pay a mechanic with recycling equipment.
@scottykilmer Heh Heh Nice job of checking for leaks, but I realise this is simply a guide and most people would go to a A/C Mechanic anyway.
Laws regarding A/C differ as you said and here in Australia it's the same What I used to be able to do I now cannot because it would cost me too much to get certified to do A/C even though I have worked in the trade like you for many years as a Mechanic
Hey Scotty, my car's AC system is completely outta refrigerant and has been for probably 8 years or so now. If I were to suddenly go fill it up, would it cause any problems with the lines or other parts after not having pressure for years? We took it in a few years back but re mechanic didn't fill it because he thought there was an electrical problem. Is it safe to fill up/recharge the system still?
@BowlingMania14 generally they are toast sitting that long, moisture gets in the system and ruins Everything inside. But if you want to gamble, put 3 ounces of pag oil in the system first, and then do as in this video and PRAY.
Nice, video explanation. I guess, we do the same procedure for re-filling refrigerant in our home AC's, say split A.C ?? right, i don't think its much different.
@danger86rangerr AH, but unfortunately it's the ONLY way to do it correctly, guessing with levels and not evacuating a system is pot luck repairing. and the stuff doesn't cost that much at places like Harbor Freight tools.
@BellumSacrumBellum28 you can, you don't have to, it just takes a little more time if you only hook up to the low side, and today, many systems only have a low side valve, they leave the high one off for cheaper manufacturing. Scotty
@scottykilmer Also the high side can introduce a liquid into the compressor which can cause compressor failure (depending on the tyoe of compressor). I teach people to use the high side for diagnostic purposes only.
@MNmale1972 Actually introducing liquid to the high side is a better way to go, however to charge from the high side you need a machine to pump it in while the engine is off. The low side is on the inlet side of the pump so if liquid is introduced it can grenade your pump. This is why its important to charge slowly from the low side so the refrigerant can vaporise before it gets to the compressor.
@72plyfury I am not saying you are wrong because you are not, however in the video he was not using a machine. As a rule, the receiver drier would be the saving device for the low side. There is no saving device for the high side. The other variables are the actual locations of the service ports. Thanks for your input.
@1989purry I don't really comprehend what you're asking. But if you're talking about the recycling machine tank, you just leave it till it's full then take it to a recycling place. Scotty
@nico27004 the gauges only fit one way, they are different size adaptors. The low side HAS to be somewhere between the compressor and the dash on the low pressure hose coming out of the dash going to the compressor. They vary immensely where on that line though. Scotty
You mean I absolutely must use a scale to measure the pressure as the refrigerant goes in? Can't I simply add the refrigerant and take my readings from the gauge itself? I'm not using a large canister as you have, I'll be using small 14oz cans.
@Moralvorstellung7 No, that's guessing as pressures change with temp and humidity outside and a problem in the system will give you false readings if it has a problem. Scales are the only way to go. Scotty
@13FravelJ the fittings only fit on their correct hose, the add low side fitting will only fit on the low side, and the high fitting will only fit the high. scotty
Hi Scotty,I look at your video to late,I didn't know that I have to vacuum the system before I can recharge it, I got an 88 jaguar xj6 that was in a garage for 8 years, the ac system is R12 but it has a leak because it was empty so I made the mistake to put R134a without vacuum the system and then the expansion valve and the 2 hoses attached to it started to leak very bad. I need your help,please tell me if a have to replaced everything or just the expansion valve and the hoses?thank you.
@tinleo333 all cars can run on that R 134a, if it is an older car, you convert it to that gas by using an 80 percent load and a few ounces of pag oil to lubricate it. Scotty
@scottykilmer i notice they have pag 46,100,150 my car is a 2003 prius witch is better & can i use the r134a cans they sell in the advance or autozone to refill the whole system after i repair the leak and use the vacuum pump?
@tinleo333 Do not work on your prius compressor IF it's an electronic compressor and not a mechanical one that runs off the fan belt. They require special equipment to work on. But if it's a fan belt driven comp, use 46 Scotty
@6400az it's the ONLY correct way of doing it, otherwise you're just guessing, which gets expensive in the long run. You can buy these tools at places like harbor freight tools and then share them with your friends and neighbors to make the cost less per person. Scotty
Yes, you are it right. I took my car to get the AC fix an they said there was a problem with the evaporator, to fix it would cost 700 + dollars. I declined, but whatever they did, my car has had cold air for the last 3 weeks.
Can empty refrigerant cause fog on my windshields? I turn AC to full and the fog just keeps building. I guess my AC doesn't remove moisture from the air.
Scotty.not abt Ac. I have a ?? Abt my cars clutch I can push the clutch to the floor and try to start the car but it starts to move when i turn the key and can't Chang gears why the car is on I have to shut the car off to select a gear
Hi, My car just started struggling to change gears the first and second gear, but the 3rd gear it doesnt struggle at all, and i cant go up a hill with the ac on, i have to turn off the ac to go up the hill, and if i put on the ac on max my car like looses speed. Help me please.
@mandayn It could be an engine problem, or a tranny problem. the only way to tell these days is with a dealer level scan tool to analyze the data coming out of the car. It's that complex today, even I couldn't tell just by driving it. scotty
@HauntedBeetlejuice you would see a compressor leak at the seals with your dye. Odds are the evaporator in the dash is leaking, pay a mechanic to check that with his sniffing machine. Scotty
Hey scotty i have a 1996 Infiniti I30 blowing hor air, i replaced the air compressor charged it up and nothing.. my pressures are reading really high.. what should i check?
Hi scotty i have a 1985 chevy c10 truck and the system is an r12 system. i was wondering if there is any way to recharge this system even though everything is r134a nowadays. Thank You
compressor clutch/pulley siezed & snapped serp belt...replaced compressor ( 00' jeep cherokee) and belt...system was empty of freon...does this mean I also had a seperate leak...or could compressor have had leak and lost its oil and freon along with it?
@HauntedBeetlejuice that's cause houses don't move, but cars do. so cars have to use rubber hoses for flexibility, while a house unit can use copper that will never crack and leak. Scotty
@cheerdiver yea, yea , wise guy. The positive pressure is in pounds, the vacuum is different. But it still says minus 30 on the gauges, so who cares? Scotty
Scotty love all your videos, I have a 98 dodge ram that keeps blowing fuses as soon as I put on my A/C. Unpluged cable to clutch and didn't blow the fuse but when connected to the clutch it blows. Could over charging the system cause it to blow a fuse or do I need a new compressor, because It looks like I can't just replace the clutch on this dodge.
@bakersfieldduilawyer adding oil is unfortunately educated guesswork. the only way to tell what's in the system is to empty it out, flush the oil out, and put a factory load of oil from their charts into the system. if a system is empty, many guys will just add an ounce for safety, assuming that much leaked out with the refrigerant. Scotty
Well damn. I sure wish I had seen this an hour ago, before my neighbor butted in and just emptied the can into my car. I had no idea I needed to flush and create a vacuum first. Have I wasted the coolant? My AC has been empty for a couple of months now. How will this affect my system and its' performance?
Hey Scotty great vid. I am having a problem with my 2004 durango. The compressor, after warming up , goes on and off. What could the prob be and what should I look for on a set of gauges?
@kdspeiser they all go on and off some, it's called cyclinn. If it's excessive, watch my video "Using AC guages to fix car AC problems" and analyze it that way.Scotty
scotty do I have to drain the coolant, before vacuum it the lines ???cuz I'm about to do a flushing and freon recharge on a 2000 dodge durango 4x4 v8 ,what would you suggest me?,please( is my first year in this profession Im about to graduate next month ^^)
@scottykilmer iight thanx scotty ,so once I vacuum the system I can drain the old coolant,flush it ,refill fresh coolant and then refill the refrigerant,right?
scotty your website button ask scotty didnt work. I cant get my 4.25 lbs that my suburban with rear air needs in the system. Im using the little cans. some have stop leak in them is that the problem? Im in dallas its 104 today and my low is reading 45psi and my high 225 but im still not cooling. FYI the compressor sounds like a bit of loose change is in it.
@johnkatiphillips well, compressors should be silent, so it's wearing out. And I NEVER use cans, too inaccurate. I use a scale and a 30 lb cannister to fill them correclty. Otherwise, you're just guessing. Scotty
@williams6975 follow the hoses coming off the compressor, they have to be somewhere between the compressor and the firewall, just keep following the hoses. Both should have little caps on em. Scotty
@scottykilmer i see 2 they look like bike inter tubes i push them in alittle with my finger nail an something sprayed out of them but when i went to the store to buy freon i hooked the end cap on the freon can to the to caps an it wouldn't fit stuff got all over now what do u think that means
@williams6975 there are 2 fittings, one for high side one for low. You only connect the add valve to the low side fitting, it's the only one it will fit on . Scotty
hi scotty my friend has a 98 Plymouth and after he changing a hose and put refrigerant, only hot air comes, and all the ac systen seen to work okay , please tell me what else can we chek.
@felipevinalay tons of things can go wrong, from clogged driers to moisture in the system. First do a pressure reading of the high and low side to see if they are normal or not. always start with that to look for pressure restrictions. Scotty
I recently bought a '91 BMW and A/C doesn't work. What would be the first step in diagnosing the system? I believe it has the R12 configuration still. I don't have gauges or vacuum pump or scales. Should I just take it to service center or maybe try the retrofit kit? Your thoughts?
Scotty, love your videos first off, secondly I bought a 94 box truck and everything is great except the AC system doesnt produce cold air, the compressor doesnt even try to engage. I figured it could be low on refridgerant, but its been so long since I've had to recharge any AC that I think I may have just filled it up with mostly air from the can and didnt actually get any refridgerant in it, so what do I do now?
i have an 18oz can of r134a sub zero with the gauge and hose on it and i have a 94 tbird how would i go by using it and know if its enough. oh and could you explain the ambient temp is its confusing me. please and thanks.......nice videos
my ac is completely empty and im going to be replacing my ac compressor. when adding the refrigerant can i just use a recharge kit sold at autozone the cans and guage they sell or do i need the big tank and hoses?
@twisted636 of course a single refill should cost less than the equipment and tank. Just price around, but realize you then have to trust other people that may not be trustworthy. Scotty
I have a 134a recharging can with a valve, hose, and gauge already attached to it. I have almost no refrigerant in my A/C system in my '96 Accord. Can I just attach the can and load? Or do I need to vacuum out first?
@scottykilmer Using the pressure gauge on my 134a canister of refrigerant, would I be able to measure if there is any pressure inside my system? I'm assuming that I can attach it to the low-side port and I should be able to get a pressure reading prior to pulling the trigger on my refrigerant canister.
I'm hoping to bypass the step where you suction out everything in order to create a vacuum.
Scotty, when you flush the A/C do you disconnect all the hoses and flush each component separately or do you just disconnect the compressor and blow it through the high side and out the low?
i have toyota SEG (in US Toyota Tercel). The problem is rpm meter is running 1000 while odometer 90-100km/h. it is normal. plz help me. zafero Malaysia
@brankovergara don't know what you're asking. If you mean how to bypass the pulley if the ac compressor is broken and you don't want to fix it, buy a compressor bypass pulley assembly for that. Scotty
Hello Scotty, I have a 2000 Mustang GT and when I turn on the AC or Defrost my engine increases in RPM which I guess i normal. But when I do it while I'm driving my car it still does it and I can feel it jerk the car forward from the increased RPM then slows it down after a few seconds. Is this normal? And is there anyway that I can get it to not do this?
@great1sniper Not really normal, your compressor may be wearing out and dragging the engine and then stopping the drag and making it race up. But, if it blows cold, I'd live with it as it can do that a long time and still work. Scotty
@xgpnastyshotz First, fix the front to get the AC system working and see what happens. The rear may have just a heating problem and the rear ac may be fixed when you fix the AC system in the front first. watch my video "fixing your car's AC: " Scotty
every time i turn my AC on my car it just blows air, not cold air? just normal air! i asked a mechanic n he said it will cost me 1000$ to get it fixed? wut u think scotty???
Thanks for the great video, Scotty. Question - after vacuuming the system, how can I be certain that there are no significant leaks, before recharging the system?
hi, scotty i have a question....i charged my truck up and it lasted for about almost 2 months now it is blowing hot air. do you think its a small leak and if so will the leak sealer stuff that comes with the refrigerant bottles work ?
@Hebert6760 Each vehicle uses different amounts of refrigerant., normally there's a sticker under the hood showing how much weight to put in. If you don't pump out any oil, you don't need to add any. Sometimes oil will be pumped out, so watch the oil level before and after evacuating, and it the level went up, put that much oil back in. Scotty
@scottykilmer hey scotty I hope you know to measure the oil level you must remove the compressor tip the oil into a container, measure it and put back in the requred amount and the right type!
@Gutsyndicate No, the old refrigerant R 12 is called by the trade name Freon, modern R 12 is just called refrigerant. Freon is merely a brand name of the old stuff. Scotty Kilmer
@MR24HRSPRODUCTIONS NO, it sounds better revv up your engine. And we call them cars, not motorcars, only the english call them that. And I'm an American. Scotty Kilmer
@happy543210 Yes, in some cases. ALL ac systems leaks to some extent, some a little, some a lot. If you have to fill it up every five years, like some toyotas, I wouldnt' waste my time looking for that small of a leak. Scotty Kilmer
Scotty, two questions: It does not appear you hook up the high side hose when pulling a vacuum. Is that correct and if you do (connect it), do you open the valve to that side? Also, I assume when you pull the vacuum pump off (you don't show this), you close the valves and then remove the pump? Thanks, this is very helpful!!

Could over charging the system cause it to blow a fuse or do I need a new compressor, because It looks like I can't just replace the clutch on this dodge.
Thanks and keep posting videos.

Scotty, great Video, thanks! But, Don't I have to add oil to the system also????
And how do I do that properly?
bakersfieldduilawyer 7 months ago
@bakersfieldduilawyer adding oil is unfortunately educated guesswork. the only way to tell what's in the system is to empty it out, flush the oil out, and put a factory load of oil from their charts into the system. if a system is empty, many guys will just add an ounce for safety, assuming that much leaked out with the refrigerant.

Well damn. I sure wish I had seen this an hour ago, before my neighbor butted in and just emptied the can into my car. I had no idea I needed to flush and create a vacuum first. Have I wasted the coolant? My AC has been empty for a couple of months now. How will this affect my system and its' performance?

@xxrenzo19 you have to use a recycling machine to suck the old refrigerant out, then vacuum out the system and refill it. Scotty

@scottykilmer iight thanx scotty ,so once I vacuum the system I can drain the old coolant,flush it ,refill fresh coolant and then refill the refrigerant,right?

scotty your website button ask scotty didnt work. I cant get my 4.25 lbs that my suburban with rear air needs in the system. Im using the little cans. some have stop leak in them is that the problem? Im in dallas its 104 today and my low is reading 45psi and my high 225 but im still not cooling. FYI the compressor sounds like a bit of loose change is in it.
johnkatiphillips 7 months ago
@johnkatiphillips well, compressors should be silent, so it's wearing out. And I NEVER use cans, too inaccurate. I use a scale and a 30 lb cannister to fill them correclty. Otherwise, you're just guessing. Scotty

@scottykilmer i see 2 they look like bike inter tubes i push them in alittle with my finger nail an something sprayed out of them but when i went to the store to buy freon i hooked the end cap on the freon can to the to caps an it wouldn't fit stuff got all over now what do u think that means
williams6975 7 months ago
@williams6975 there are 2 fittings, one for high side one for low. You only connect the add valve to the low side fitting, it's the only one it will fit on . Scotty

@felipevinalay tons of things can go wrong, from clogged driers to moisture in the system. First do a pressure reading of the high and low side to see if they are normal or not. always start with that to look for pressure restrictions. Scotty

I recently bought a '91 BMW and A/C doesn't work. What would be the first step in diagnosing the system? I believe it has the R12 configuration still. I don't have gauges or vacuum pump or scales. Should I just take it to service center or maybe try the retrofit kit? Your thoughts?

deadgameful 8 months ago
Scotty, love your videos first off, secondly I bought a 94 box truck and everything is great except the AC system doesnt produce cold air, the compressor doesnt even try to engage. I figured it could be low on refridgerant, but its been so long since I've had to recharge any AC that I think I may have just filled it up with mostly air from the can and didnt actually get any refridgerant in it, so what do I do now?

@twisted636 You can do anything, BUT it's VERY hard to get the exact right amount of refrigerant in using those tiny cans. Scotty
scottykilmer 9 months ago
@scottykilmer about how much would a service center charge to refill it would it be cheaper then buying the tank and hoses?

@twisted636 of course a single refill should cost less than the equipment and tank. Just price around, but realize you then have to trust other people that may not be trustworthy. Scotty

I have a 134a recharging can with a valve, hose, and gauge already attached to it. I have almost no refrigerant in my A/C system in my '96 Accord. Can I just attach the can and load? Or do I need to vacuum out first?
purplefetus3 9 months ago
@purplefetus3 If it still has pressure inside, you can add as air is not in the system.. Scotty
scottykilmer 9 months ago
@scottykilmer Using the pressure gauge on my 134a canister of refrigerant, would I be able to measure if there is any pressure inside my system? I'm assuming that I can attach it to the low-side port and I should be able to get a pressure reading prior to pulling the trigger on my refrigerant canister.
I'm hoping to bypass the step where you suction out everything in order to create a vacuum.

scottykilmer 11 months ago
Hello Scotty, I have a 2000 Mustang GT and when I turn on the AC or Defrost my engine increases in RPM which I guess i normal. But when I do it while I'm driving my car it still does it and I can feel it jerk the car forward from the increased RPM then slows it down after a few seconds. Is this normal? And is there anyway that I can get it to not do this?
great1sniper 11 months ago
@great1sniper Not really normal, your compressor may be wearing out and dragging the engine and then stopping the drag and making it race up. But, if it blows cold, I'd live with it as it can do that a long time and still work. Scotty
scottykilmer 11 months ago
i got a rear ac unit and it doesent blow hot or cold.the front blows hot but not cold just normal air even if its on max ac.
xgpnastyshotz 11 months ago
@xgpnastyshotz First, fix the front to get the AC system working and see what happens. The rear may have just a heating problem and the rear ac may be fixed when you fix the AC system in the front first. watch my video "fixing your car's AC: " Scotty

Hebert6760 1 year ago
@Hebert6760 Each vehicle uses different amounts of refrigerant., normally there's a sticker under the hood showing how much weight to put in. If you don't pump out any oil, you don't need to add any. Sometimes oil will be pumped out, so watch the oil level before and after evacuating, and it the level went up, put that much oil back in. Scotty
scottykilmer 1 year ago
@scottykilmer hey scotty I hope you know to measure the oil level you must remove the compressor tip the oil into a container, measure it and put back in the requred amount and the right type!
