Doing This Will Make Your Car's AC Blow Twice as Cold

Rev

your

engines here, we have a common problem: a car that the air conditioning won't cool. Now it turns out

this

is a Honda and the most common problem was simple; over time they lose refrigerant, so it's 2007, so "We're talking about a 16 year old car, well what happens is

this

. You can see the original air conditioning compressor is down here. Use the fan belts to drive the compressor, so that the compressor has a shaft that rotates well. That shaft has a seal that keeps the refrigerant from escaping, but here's the thing: it can't be a perfect seal because if it were a perfect seal. it would burn the metal of the axle, rubbing the rubber would burn it, so it selectively leaks some coolant and cooling oil that lubricates it all cars lose coolant over time, but Hondas are more prone to that I often see Hondas. that are two, three or four years old and I already have to add coolant, which is normal now in a Toyota, they are a little bit better sealed Systems in Hondas, now you can do it

your

self if you don't trust the mechanics to charge 150 per hour and you say, well, you need a compressor or a condenser, you need all this work often, you just need refrigerant, now that's the only thing.

You have to know that there is R134a and the new R1234yf with a stupid name and also a stupid idea because it is partially flammable. Including this, I'll tell you what you have. You can see the air conditioning system here. Now we

will

remove the dirt and it tells you that it takes 0.550 kilograms or 19.4 ounces and it also says type 134a coolant. You can get these cans almost anywhere 134a and here's the other stinker: the new, two, three, four, YF costs 10 times more than stock, which is absurd, it probably costs three cents to fix, but it's a new anti-pollution, it doesn't ruin the ozone layer the reason they came up with this for free because they said it didn't ruin the ozone layer but now they got to glue the back so you know it still ruins the ozone layer so we'll

make

one that It doesn't ruin the ozone layer at all, but if the car starts to burn, it could burn you, that's okay, right?

You can buy it. this in most stores in most places our government has to take care of absolutely everything, but you can still buy it now. There are some states where you can't because they say only a certified technician can put this in, but as you'll find Well, it's not hard to do it now if you want to do it yourself and I guess it's not that hard to do. You have screws to tap into this. You can add it little by little until it starts to

blow

cold

and if you have one of those announcement systems that has a little indicator, you can watch the indicator and when it goes green before it gets to red, you can do it that way and they

will

probably call you AC, but I'm going to show you how to do it the right way because today's systems use a very small amount of refrigerant these things used to use five six pounds you want to do it right you don't want too little or too much so the first thing you really want what to do if you want to do it properly you get the low pressure connector from the gauges and stick them on low, this says low, not all of them say low but it only fits on one if you put it on the big one. doesn't fit in this case, it was spot on.

You see, it's about 40 PSI, it should be like 90 or something, so we know it's low, so what we're going to do, you can add it if you want, like I say, keep adding. and if the pressure rises just right, it's good, but see that the pressure depends on the outside temperature, the outside humidity, even the altitude you are at, it's much easier to just suck it all in and then add the factory charge which you already have. We know that it is 550 grams. Now there's also another reason why you really want to flush the system because now, in this guy's case, we don't have to worry about there being anything else in the system because he's the original owner and he gave it to his son, to nobody else. has been working on it I think, but let's say you have a car or someone worked on it, if some fool works on your car and air gets into the system or they put the wrong coolant in it and add stuff on top of it.

We are going to compound the problem here and the assist system will destroy an air conditioning system so it is best to just suck it out then you will know there is absolutely nothing inside except a vacuum and when you add the refrigerant you will know that what you bought is real. there's nothing else there with it so it should work pretty well and it doesn't generate gas if you follow the pressures you're guessing, if you pass put a little bit it's generating gas this way there's no gas anywhere. ones for freon and if you have the new one, two, three for a while, guess what I have adapters in the garage and you have to put an adapter on it because each system, thanks to our government regulation, has a different thread size, so it's a craziness. continue, the vacuum error appears and it will remove everything, also it is also emptying all the water vapor from the system if anyone has water vapor in the system it will destroy your system like a part of a thousand of the water vapor consumes all your air conditioning system, so by

doing

this, you are

doing

two things: getting rid of what is in it and also getting rid of the water vapor that is in the system, which is why it is a good idea to vacuum.

Okay, it's sucking, you can see here, this is the new can and they actually have a valve built in, so this tap can is made for that. I'll unscrew it and show you it's a little piece, it's pointless, it's flat and it opens the valve, some of the older styles have the same tap but it has a pointy end because it's just bare steel and it punctures the hole they made to that it does not leak into the atmosphere, it is a better system and almost all the cans that you buy today will be like this and while we wait you will see that it is 340 grams, correct, 340 grams and we were 550.

So we will put all that in that is simple, but then the other. is 340. So how do we

make

it 550? Well, you look at some basic mathematics. 550 minus 340 is what 210 is. Why the hell do you buy it? You can put it at 210 grams, in Tennessee. I don't even use these. small cans, I use a giant big 30 pound can, it goes in reverse scale, well in this case I just bought this postal scale, it's like I don't know, 20 dollars on Amazon, you just put it in, you'll see and then when It goes over that weight and there are 210 grams less.

I turn it off and we know it's exactly the same amount now. If you don't have a scale, you can guess and say oh, it feels

cold

, but what's the point is to make it accurate and you might also be able to use this proportional wait. You know you can't weigh yourself unless you're very small because the maximum is only 50 pounds, all the vacuum pumps are stable and what you can do here is the track we're closing. vacuum pump and what we do is we look at the gauge, if the gauge goes back to zero that means there is a leak in the system that needs to be fixed now we know there is a leak but it's been like six years it's a leak so small that I'll never find it now, you never know, although maybe in the last week, all of a sudden, the big leak happened, then that thing would go down to zero, we'll see what happens, look what you see, it stays stable, 10 pounds less pressure, whatever the gauges.

It's not exactly exactly exact, the main thing is to make sure that it doesn't move and that it doesn't move, so what we're going to do is screw the can that opens the valve on the inside. There's a small amount of air in this hose here. and you don't want that air going into the system, so this is a good set of gauges and it has the little gay baby trailer, there goes the air, the air is not out of the system, so there is no more air, pushed it up so now make sure the vacuum pump is closed and then what we're going to do is open up the feed line that's here and open it wide the coolant is starting to come in now it's just a small amount coming in of coolant. to get in without the engine running, so now we're going to start the car, you need to have the system running, so turn it on, turn the air conditioning on full power, start vacuuming it. 10 cools down and you want slower the better if you introduce too much refrigerant too quickly it will all wear out the compressor.

You can actually fold things inside so the slower the better. You don't want to do it as quickly as possible. You want me to add the system slowly. this one stopped so we're turning off the coolant line you're no longer connected to the hair which I just can't help but put the other can in and you're like a little whistle it's never perfect now that we have the other can but we're going to make this a little different, we'll open it, we'll let it out here, even if it urinates the air, we'll put it on the postal scale, so we'll turn on the scale. and we want it in grams, we have a zero, the system for zero grams, now we have 562 grams, that's what she put in 340 and we want 550, okay, the only one, 210 Grand, so we'll watch this until I lose 210 grams, which is when you will pay 356 thousand dollars, so here we go, in fact, going down slowly but surely and I can feel inside that it is starting to get cold up to 400 degrees now and, like I say, don't rush because if you put it on too fast You can bend the valves inside the compressor and it's not what you might think.

It's not like a car engine that has metal valves in the intake. These are plastic valves and can break very easily, so take your time when doing this a lot. Guys, you're just going to open everything wide, shake it up and get it in as fast as you can. They have no patience, getting closer and closer. That's done, turn it off and while it's running, we'll remove it and the reason we're removing the line. what's working is because there's less pressure, it's disgusting if you turn off the car the pressure will go up to 90 pounds and more will leak when you quickly remove the fitting and when we get in it's nice and cold I see.

You can see it's not that hard to do now, like I said if you want to be cheap you can get it and add it until the stock is cold and blonde, that's good enough for you, not good enough later you have to add a little , you can add a little. correct, but this way we know we have a factory charge and it will last longer and you will know it is correct, plus we know the system is working now, so we know the system is fine, let's say the system has a problem and it just starts Adding refrigerant can have all kinds of problems with too much pressure on one side can cause catastrophic compressor failure if it sucks it all up you know you put in the right amount and in this case it is working this is the second time this has happened. made on the car, it's the original owners, you give it to a son, if you have to add it from time to time, it's cheap, well at least this is cheap because it costs 134, go to the auto parts stores and you will find a new one . r1234 YF is almost a hundred dollars a can, so now you know, it's a common problem with all cars, especially Hondas, they will leak some coolant, why don't you learn how to put it back in yourself and like I say, if you want to do it right? use a vacuum pump hey AutoZone will lend you if you don't have gauges guess what don't make the gauges too so if you don't want to miss another one of my new car repair videos remember to ring the bell thanks.
