Then once the clip's off, then you can just grab the line, pull it out. And just grab, you need to find the side that's open, just slide underneath the clip, just using a 90 degree pick, and then slide the little clip out. But what you can do, you can take a pick as well. But normally they're pretty difficult to take out that way. You slide the tool on, and then you twist it, and it's supposed to spread the fingers and then you grabbed the line, slide it out, and it came out at that time. They make special tools, this is one of the plastic ones. So there's a little lock ring in here, kind of like a snap ring. There's a little cap on the line, slide the cap off. Next we're going to take off these transmission cooler lines. I'm just going to take this hose clamp off, my hose clamp pliers don't fit in there, so I'm just going to use some needle-nose pliers. Get the hose clamp off this area, then we can grab the hose and just rock back and forth. I'm going to use some hose clamp pliers, just release this hose clamp. Now we're going to take this upper radiator hose off. And then when I tried to compress this, this side broke, because you can see it's a little shinier right there. So that's why we're getting a coolant leak.

And then it wasn't able to clamp the radiator good enough. This broke before, you can see that broke off. And it looks like this broke because it's rusted right there. This would go on like this and that's what puts pressure on the coolant hose to secure it to the lower radiator. And here is the clamp and as you can see it broke right there. Take this tool off, release that, set that aside. Just going to use a pry bar and be careful if you're reusing your radiator, not to ruin the fins or anything on the radiator. And because this clamp is really rusty, I think it actually just broke on me. So I want to make sure I have a bucket underneath to drain the coolant, and then I'm going to tighten up on this clamp. It will go onto the clamp right here, and then when I tighten this up, it's going to tighten up on this cable and that will open up the clamp so that we can release it. To get this clamp off, I'm actually going to use this tool.

So I'm going to have to release this clamp and take this hose off and that's how we're going to drain the radiator. Get this out, and pull that straight out just like that. You got to get it out of the way of the coolant upper radiator hose. There's some clips right here on this side where this clips into the radiator. Now we're going to grab the fan shroud, and we're going to just lift up. Now we're going to take these two bolts out, this one here, one over here, going to use a 13 millimeter socket and a ratchet.

And then push it down, and you'll be able to get it out. Take a little screwdriver, and pry against the lock. Sometimes these connectors get a little stuck. Just push down on the tab, then wiggle the connector down just like that. Now we're going to disconnect these electrical connectors. Then we'll do the same for the bottom one. It'll just stay on there, because the little thing on there. What that means is that the bolt's not going to come off of that bracket. And normally these are caged so you can just slide them out of the way. Take those two out, use a 10 millimeter socket and a ratchet. These hold the transmission cooler lens on. Alright, next I'm going to take these two 10 millimeter bolts out. Might be easier with a smaller like pocket screwdriver. We'll just take that, just take a straight blade screwdriver, just push this in here. Because when it goes together, it's got to push down. There's some tabs on the bottom that lock into a grommet, and then this actually, we're going to have to move this. Just grab the whole air box, slide it out of your way. I'm just going to grab the front side of the mass airflow sensor, or the front side of the air box and just slide up. Take that hose off and then set this aside. There's a little hose right here that just connects to the valve cover on the passenger side. There's a worm clamp over here on the throttle body, right there, loosened that up. You can take this snorkel off here, slide it off. Pull the connector off, and we'll loosen up this worm clamp right here. Disconnect this mass airflow sensor connector.

In this video I'm going to be removing and reinstalling a radiator in this 2008 Chevy Silverado work truck.
