Hey there viewers and welcome back to the self made all the channel. That's our 2007 chevrolet, it's a half ton. It's got the big 4.8 and the engine lights on a big 4.8. I don't know why gm made the 4.8 we'll skip that thought.

Uh. Let her go through a system scan we're going to hit report here. Uh, let's see here, we have lo and behold: evaph leaks, a small evap leak and a large evap flex. We have both left front speed sensor and some more in the audio.

So, let's just hop right in here we're gon na go to the pcm and let's just first of all, see if we hear the canister vent valve, it's not in this menu must be in this menu. Let's just see if we can hear it clicking uh, i don't hear it snapping back, even though josh is making noise over there. Usually these are pretty noticeable. I don't hear it.

Let's uh oops we're gon na have to go down on this old girl and see what uh. What's going on in there is our fuel tank sensor working fuel level. Sensors looks like that's pooched um fuel pressure should be good or fuel. Tank 1.5 is usually atmospheric pressure.

Oh fuel level sensor rear tank. That's why that one looks screwy, okay, that one's correct, um. Well, this is all in canadian. That's weird they're setting screwed up here.

Anyhow, let's uh! Let's get this truck up in the air because we're not rookies. We know that before we pick up any vehicle on the left, a put a battery charger on it or a maintainer, which we already did and b it's probably going to be pretty rusty, underneath so we're going to need a good power and a ground source. Potentially so we're going to hook uh power probe up, so we have that underneath there we go all right there. She is so here's the cancer medley.

You see, it's been changed before see all these clamps here. Well, all three of them are rusted off it. So it's kind of interesting, so it's been back on here, a while somebody's replaced. That's definitely aftermarket.

Now i got the scan tool here. So let's listen! Yes, i'm clicking it on off. I definitely don't hear it clicking. So i like to try that before i touch it.

Oh that's a brake line. No, that's the easy way to do it. Fella uh! So let's unplug this i was gon na, say i don't like uh touching them before. I click them on off because sometimes touching them fixes them what's up.

Miss, though, would there be any benefit of changing the thermostat when you flush the heater core on which vehicle would it be 17 ram? 17 ram, i mean i, i can okay nick that misses a lot squared away uh. We got this unplugged. So what we should have back here in the gm we should have full-time power on one of these wires. I think the pink one or the orange one there and we do and then the other wire here is going to be our control wire and when we turn it on.

Currently it's turned off when we turn it on. The computer should pull that to ground. Now. The power probe here actually has a test for that.

We could just use a test light power probe calls it the driver test. I believe it is so hit enter and let's see it's going to put a small load on this wire, so it has right now. Currently, at the tip 13.76 volts because we have our maintainer on it, so we're going to put that on the control wire and then i'm going to use the scan tool and turn it on turn it back off. So that tells us that our circuit is intact.

Now, if you don't have a power probe, you can just use a quarter amp a test light. Let me show you: this is going to be your classic. 194 bulb we're going to probe it in there probe it in there, and this is going to make sure our whole circuit can carry current, which it should we'll turn it on. We can see it comes on and then we turn it off.

So super duper easy. Our canister vent valve is garbage super common problem on a gm before we do any other evap leak, testing or any other event testing. We need a functioning canister vent valve this one. Clearly, you know doesn't work, looks like it's been underwhelmed, i'm going to get a new one, uh, probably when we take off, we probably will see where it's split open.

Usually these things get moisture in them and they actually physically crack open here on the solenoid. So pretty common, let me get a new one, then we'll see if the system can actually seal and purge our friends at naver showed up. They brought us the new canister vent belt. So we can proceed to take this one off.

The good news is, we don't need a screwdriver or a nut driver to take the clamps off here, so you've just rusted away. However, we do need to be careful of the brake line uh. Typically, you don't need to be careful of the brake line because, as a general rule, it's not right here now this nightcap before we go yenga. It is not that i got.

This is just the old-fashioned green stuff and we'll very gingerly move that out of our way, they've got it fastened over there. Quite well, so we're not even going to bother zip tying it back to this canister that belt we're just going to move some of this stuff. One good thing about new york cars: you don't need a lot of tools, just a good kicking hammer, get the rust out of the way. Oh, my god, it's not even fast into the tank even better.

Let's see this is the best side, the fresh air side. This is the belt or the on the other end of this hose, oh gosh, i'm being a whisper i've been off for a week. Folks give me a break. We took a little time off around christmas and new year's.

Can you say christmas? I think so think you can you, mother walker. What happened to me? Did i grow a vagina? That's probably more offensive than say christmas. Holy cannoli, better check, my pocket. Oh great, oh, it looks like they might have used a piece of garden hose.

Why am i out of breath? This looks like garden hose of some sort, yeah pretty sure, she's stiff, it's green inside of it's all chowdered up chewy, let's open up your new one, uh, it's your classic! 2282-614 from that right from mainland, oh made in usa. It says wow i was going to save it from the mainland, but it's actually america, here's our new one, there's a general rule. These go on the tank like so what's up miss though i just said something offensive on youtube. Oh boy, do you want to repeat it or click that on there uh i better not it was kind of a sexist.

Oh wow, you know what i'm saying. Well, actually, i said the word christmas first of all and then i said something sexist, because i wasn't thinking you know how you tell me think before you speak, or was that my mother, that used to say that i'm sure we both told you that probably both Have said that a timer too, do you ever think before you speak all right? We need to go, get a little piece of rubber hose and we'll come back and talk more about christmas chop, this off a piece of hose. Let's stick that on there i got us some new hose clamps too here and here so as it when this uh was stopped. Now this would have had the tube molded right to the vent valve.

That belt would have been one of the big ones with the filter in it, and gm came out with this bolt and a long time ago that you, you know you chop it off. You have this new valve and you take and put a piece of hose on it, and you run it way up above the transmission. Then you put this remote filter kit on it and all that stuff uh. If you, if you live in the northeast and or any part of the americas and or any part of the world that is considered the salt belt, don't don't waste your time doing that because that's all it is a giant wasted time.

If you take your time to run this up above the and put the remote filter, relocation kit, it still doesn't work uh. These things will still fail within a year or two. So don't uh, you know, don't bother running that all the way up there under the hood and all that stuff. It's just a waste of 20 feet of deer hose we'll find out where the the person ran this one.

Sometimes people just stuff them up in the frame rail. It really doesn't matter. Usually i just mount the filter back here because it really doesn't matter look at there's that, let's see where they ran, that hose baby goes up there. Oh man down hold on folks.

So there's the hose right there, oh maybe they did run it the whole way, they're going all the way. Oh nope, they ended it right there. So that's this little block right there. So, like i say it, doesn't it doesn't matter where you put it? The bed valve still goes bad all the time.

Sorry about the noise folks uh, it's pretty chilly today, so i've got the furnace on. Obviously, it's really bizarre because in real life irl is my kids will say: the furnace is not loud. It's actually quite a quiet furnace, but on the youtube videos. It's like this, the whole time in the background, but frankly i don't want to be cold on this side of the canister vent valve.

You can choose to put a clamp on it, which really doesn't matter. This is the fresh air side. This is the canister side. Now this side does have to be sealed up point like a tiger, because this is the one that goes to the first side or the canister side.

This side has to be tight. This side. If you got a little leaky, it doesn't matter. That's not gon na leak, anyways you've seen how hard it stuck to those barbs.

Let's go get the skin. So let's make sure this thing clicks she's clicking now, hopefully you guys can hear it as i turn it on and off with a scan tool here. All right, so that's good uh because it clicks. We know it's good, that's false.

I tried to trick you. However, our furnace can help us at this point we're just griping about the noisy furnace, or at least i was what we can do is we can seal the system? Now click you just heard it click now, technically, with the furnace being on. We should start to see an increase in pressure if there is no leak in the system, and we can see immediately. It's popping up already our fuel tank uh pressure sensor voltage is going down.

Pressure is going up because this is just like a having a gas. Can in the back your truck in the middle of summer - and let's say you put it in there at night time and you know you had it all sealed off you come out in the morning because you slept in and you're hung over and you go out There and this thing's blowing up the size of a balloon and you got to reach over and open it up. Well, the same thing: we've got this thing inside we're not hungover, but we sealed off the entire tank by shutting off the canister vent valve the purge. Solenoid is closed.

So therefore, our tank with our furnace on is heating up and starting to expand and starting to build pressure, albeit very very minute amount of pressure. We can confidently say that this system is sealed and it likely does not even have a small leak. So when i open this, this should go back to atmospheric pressure right bada, bing, bada boom. Look at that we're done so.

Hopefully that makes sense to all you folks, uh. I think it does a lot of times when you explain it about the uh. You know the gas can, because we've all done that you know you've had the gas can in the cold, and you know the side sucking on it. And then you know on the heat that things popped up like a balloon and there you go and that's very similar way to uh explain how cars that use nvld systems, so natural vacuum leak detection, that's what they do.

They are dependent on changes in our climate. You know the hot the cold, that's when they run their very small evap leak tests. Typically, that's how they'll run them is just natural vacuum. Can this thing doesn't go into a natural vacuum? So chrysler is huge on that ford.

Does that there's several manufacturers that use the nvld system, so this one does not, but you can still do it with the scan tool, because if we let's say for example, we closed that canister vent off and nothing changed. You know that fuel tank pressure just sat at you know 0.08 millimeters of mercury never moved well. At that point we either have a bad fuel tank pressure sensor or we got a big old leak and then which case we would close it close the vent. And then we would put a smoke machine on it and say: hey, you know, where's the leak, or at least that's one approach you could use.

So that's that this tells me our system is sealed. The only thing i need to check now, uh, when i set it down before i pull it out, is i'll, open and close the purge valve to make sure it works. We know it's closed, but can it open so because the light's been on in this truck for about six months? He told me so that's that what i'm going to tell you is to go into that comment. Section.
