What's up guys? I'm Andy from 1A Auto. In this video, I'm going to show you how to replace the throttle body on this 2010 Toyota RAV4. If you need parts for your vehicle, click the link in the description and head over to 1Aauto.com.

Disconnect the negative battery terminal. We'll use the 10 millimeter wrench. Loosen this nut up and pull the connection off and set this aside. You don't want this to arc out on the battery, so make sure it doesn't spring back. And then disconnect the mass air flow sensor right here. Just push down the tab. Release the connector. There's a wire retainer right here. Just get a trim tool. Get underneath there. Pry it up. Just like that. There's one over here as well. Take that wire, disconnect that wire.

I'm just going to use a 10 millimeter socket and ratchet. Loosen up this clamp right here. Pull this snorkel back. Just like that. I'm just going to release these clips on the air box. Get those off. Get the air box out of the way. Pull the air filter out while I'm doing that. I'm just going to use the 10 millimeter socket extension and electric ratchet to take these three bolts out of the air box. You don't necessarily need to take this air box out, but it's going to be better for the video. And also I might have a little more room.

I'm just going to use a pick to remove this wire retainer right here. And just kind of spread this apart. Should be able to get it to unclip. There we go. Slide that wire out, grabbed the box, slide it out. I'm just going to remove this cover to get it out of the way. Just grab underneath and pull up, slide it out.

Now I'm going to take this bracket out. You can try to use a Phillips head screwdriver to loosen up that stuff that you can pull this valve off. But the screws pretty tight on this one. So I'm just going to use a trim tool and we're just going to pry the bracket out of here. Just like that. I can just take this hose out of the way, and I'm just going to take a hose clamp, hose clamp pliers, take this hose clamp off, loosen it up. Try to move this hose to separate it. It's not separating too well. So actually I'm going to separate it over here. Take this hose clamp off. Slide that down. Just grab the hose and twist. There we go.

I want to loosen up this hose clamp right here. I'm going to use a cable style hose clamp plier. Slide it over the hose clamp and loosen that up. That loosened up. Try to grab the snorkel, just rotate it and pull it off. There's the vacuum line right here. This goes all the way over to the brake booster, so slide that out of the bracket and there's a 10 millimeter bolt right here. I'm just going to use a 10 millimeter socket extension and ratchet. Take this bracket it off. I'm just going to leave everything attached to the bracket and just move it out of the way. And just slide this to the side. There's some hoses attached on the side here. It's going to be kind of hard to see, but we want to take those hoses off.

This one just has a little clamp that you can use just your fingers to move it and you can try twisting the hose. Now take this hose off right here. If you need to, you can take a right angle pick and just get in there and loosen up the hose. There's another clamp on this vacuum hose that you can either take it off right here or take it off down there. I'm just going to use my hose clamp pliers, squeeze the hose clamp and just try to move it down the hose and twist the hose and wiggle it off. There we go. Got it off. These hose clamp pliers work pretty good. You just line it up with the clamp and then squeeze it. That's how they work.

So there's one of these hoses that still attached to the intake that goes to the solenoid right here. The bottom hose, you're just going to have to try to get that one off. You can either disconnect it on the intake or disconnected on this side. It's just a vacuum hose. If it's pretty brutal, you could just cut it and just replace it. Just going to use the pick. Here we go. A little bit of vacuum there, slide that off. Disconnect the connector right here. Push down on the button, slide that off. There's the button.

There's a fuel line right here. Just move that fuel line out of the way. You could take this bracket off if you needed to, but we'll just move out of the way for now. And then there's two coolant lines that go to the throttle body. Now what you could do is just pop those lines off, but you're going to lose a lot of coolant. So I'm going to use these coolant pose pinchers. We actually sell these at 1Aauto.com. What you're going to do is just put one around here like this and then just tighten down the wing nut that's going to tighten off the coolant, prevent some of the coolant loss. Still good idea to top off the coolant after you've done the job. But this is going to prevent a lot of coolant from coming out. And you don't have to tighten these too tight. Just snug.

That should be good, and I'll put one on the other one as well. So just make sure there's no pressure in the coolant system. Just grab the radiator hose and give it a squeeze. Make sure it's not hot before you pop these off because you don't want to give a face full of coolant. And we'll use the hose clamp pliers. You can probably use regular pliers to get these clamps off to. Just hose clamp pliers work a little better. Just move those down like that. Same with this one. You take a pick, right angle pick and just try to pop these lines off. Get in there. Going to lose a little bit of coolant. You can put a bucket underneath the car to catch any of the coolant. And slide that off. Just like that. Not too much coolant. Same with the other one.

I'm going to take these four bolts out. I'm just going to use the 10 millimeter socket and an extension and a ratchet. Take these out. With all those bolts out, just grab the throttle body, slide it up. Just be careful with it. Don't drop it.

Now I can take this rag off. I did put a rag down over this throttle body opening in the intake so that I didn't drop anything in there. Take that away, and it'd be a good idea to replace this seal right here. We're not going to because I don't have another seal, but you can just pull up on that little tab right there. Get a new throttle body seal. So that looks good. Slide the throttle body in position. Now if it's easier before I put the bolts in, you can hook these hoses up, line that one up on the bottom and this one goes on top. Little bit easier to do that before you put the bolts in, and we can take these little clamps off. That's just for coolant to go through the throttle body. Keep it cool. Slide those off and you can use pliers if you don't have hose clamp pliers. Sometimes it's easier. Just move those hose clamps down in position. Same of this one. Make sure that bottom hose is all the way on. Here we go. That's good.

Now we'll take these four bolts, get these bolts started. Take a 10 millimeter socket and a ratchet. We'll tighten these bolts down. Then I'm going to take the same 10 millimeter socket and a torque wrench and torque these to seven foot pounds.

Take the connector, line the connector up, lock it in place. Take this fuel hose, line that up in that bracket right there. Kind of take this hose in the back. I'm going to connect this hose to this hose and then take the clamp and line the clamp up. You can do it with your fingers. You shouldn't need pliers, but if you do, use pliers, and then that's going to go right there. Just like that. Now you may not have taken that off for replacing the throttle body, but if you did put that back on. Take the lower portion of the air box line is back up.

Then there's three bolts. Take the three bolts. One goes right there and then the other two down here. And we'll just snug those up. Use a 10 millimeter socket and a ratchet. Tighten these down. Install the air filter.

Now we're going to take this snorkel, and I have my hose clamp already started on the hose clamp. Hose clamp tool started on the hose clamp, slide it over the throttle body. Oh, it popped off. I'm just going to have to reset that. I got it close with the other hose clamp tool. Now I'm just going to position it a little bit better, and it looks pretty good right there. And this hose is going to go right here, and this solenoid by this valve is going to go right here. Slide that back in position just like that. And we'll take this hose, slide that right onto the valve cover, just like that. And you should be able to pinch this with your fingers. This hose clamp on might be a little easier to slide it down before you slide it over the valve cover right there.

We want to take these two years of the box and those are going to go in the back right there where the slot. Just move the snorkel out of your way. Slide that in position. Make sure this cable is out of your way and lock this in place. That's good. Slide the snorkel back on. Just like that. Just plug this in. Plug this into the mass air flow sensor and then the retainers right there and right there. Now let's tighten up that worm clamp. You can either take a Phillips head screwdriver or a 10 millimeter socket and ratchet and tighten this down.

And take the engine cover, line this back up and push it back down. And take the battery cable, re-install that. You can use a 10 millimeter socket or a 10 millimeter wrench and a ratchet. Snug that up. Just make sure it's snug, which is good. After this job, you're going to want to make sure you take the coolant cap off and top off the coolant. If a lot of coolant came out, then you're going to have to bleed the system. So use the appropriate coolant. Check your owner's manual. You can use a funnel to do this if you wanted to or just be careful. So you're going to fill it up and you want to let it run. Monitoring the coolant system for about 10 minutes. If you put the heat on low, and then watch the temp gauge and shut it off in 10 minutes and recheck the level. Put the cap back on.
