What's up guys? I'm Andy from 1A Auto. In this video I'm going to show you how to replace the intake manifold runner control in this 2001 BMW 325xi. If you need this part or other parts for your vehicle, click the link in the description and head over to 1aauto.com.
To remove and replace this intake manifold runner control, you don't necessarily have to take all these panels off or this cover or even the airbox, but it's a lot easier for us to show on camera taking it out. With the trunk open, over on the right side or the passenger side, there should be a cover that goes right here. This vehicle doesn't have one, but you're going to want to remove that cover. The battery is located right here. First thing I'm going to do is take a 10 millimeter socket and a ratchet, loosen up this nut for the negative terminal, that's loose. Slide off the cable, slide it out of the way.
I'm going to take these push pins out right here. I'm just going to use some side cutters. Get this center pin, pull that up and then slide it out. Be careful not to cut it, get those out. Just grab this piece and slide it out. I'm just going to disconnect this connector to the mass airflow sensor. Push down on this tab. Wiggle it out. Take a straight blade screwdriver, loosen up this clamp right here. Should be good. Can push that snorkel off right there, and there's all these clips holding the top of the airbox off. I'm just going to take the top off. And this last one over here, it was kind of tricky to get to, pull the dipstick out of the way. And just grab the airbox, pull the air filter out.
I'm going to take these two bolts out, I'm going to use a 10 millimeter socket extension and an electric ratchet. You can use a regular ratchet if you don't have an electrical one or an air powered one. Loosen them up. Take them out. Then we just grab the airbox. Slide it up. This wire is on it, this little grommet right here, just try to slide that out. All right, take that off and just slide this out of the way. I'm going to take this cover off right here. Just take these clips, twist it to the side, just like that. Grab this and slide it out. This weather strip might be in the way, it should slide forward, and take the cabin filter out. It slides out as well.
I need to remove these wires from this housing right here. You can either take the cover off or you can slide it up right there. I like to take this cover off. Just take a screwdriver, slide that off like that. Pull that out of the way. Grab these wires, pull that down, pull this one down. I'm going to use a T30 socket extension and a ratchet and I have four screws right there. Take those off. So it's all loose, you can you just slide this panel up, slide it out of your way. I'm just going to take this weatherstrip off and just slide it up. There's a retainer right here. Slide this retainer out and then slide these hoses off here in the wiring. You should be able to slide this up. You might have something holding this in near the firewall, but this vehicle doesn't have that so. And just sneak it past the hose and then slide it out.
Disconnect this connector right here, there's a little push retainer right there. Slide that off. I'm going to take this valve out. I'm going to use a T30 and a socket and a electric ratchet. You can use a regular ratchet if you don't have an electric one. There's a screw right here on top and there's another one underneath here, right about there. Just like that. Take those out. Just grab the valve and just slide it out.
All right, now we'll take this and just slide this back in position, just like that. Take the two screws, I'm just going to use my T30 socket to help get these screws started and then same underneath here. And then I'm just going to take my electric ratchet and just snug these up. Not too tight. That's good and that's good. Take the electrical connector, line it up and plug it back in. So now we're going to reinstall this panel. Just slide these wires in this vacuum line up, and if you struggle to get this in, you can always pull the vacuum line off the brake booster, just pop that out.
There's a couple of coolant hoses over here. So underneath here there's a clip that has the coolant hoses on, that's going to actually clip to the cover. So you just slide that up. That's good. Slide these hoses back in position, that and that. Pop that back in the brake booster. Take this clip retainer, slide this in position, press it in and twist it, just like that. And if you have another one, put that one in as well. Slide the weatherstrip over here, just like that, and then you can reinstall that cover up top.
Now we're just going to slide this side of the lower airbox in here. Yours may have something that this connects to. This vehicle doesn't. Just slides in position and then this lower part slides there and make sure these holes are lined up. Take these two bolts, get these started. Take a 10 millimeter socket and a ratchet and tighten these down. I'm using an electric ratchet. If you don't have an electric ratchet, just use a manual one.
The air filter, reinstall it. I'll take the top part of the airbox, I'm going to slide it onto the snorkel first just like that. And then there's all these clips, take these clips, lock this part down. Connect the mass airflow sensor and air flow meter. I'm going to slide this clamp right here. Take a straight blade screwdriver and tighten it down. Just snug, not too tight. Give it a shake. Make sure it's good. Take this piece, slide this into the airbox, just like that, and there's retainers right here. Take those push pins, lock them down.
All right, now we want to install this. Just get this lined up. Can get these screws started. I'm going to take a T30 socket extension and a ratchet. Tighten these up. Now reinstall these wires in this cover right here, just like that. Take this cover and line it up and that's good. Take the filter. We're going to slide it in with the curved side towards the vehicle, so the bode side more towards the out of the vehicle. Just slide that in position like that.
We'll take this cover. It's going to just slide in underneath this weatherstripping. Just push it in, get these lock tabs to line up and lock them down. They're spring loaded, and the last one and you're good to go. Now we can take the negative side, connect the negative side, take the same 10 millimeter socket and ratchet, tighten it up. That's good. At this point, if you had that cover, you're going to want to put the cover back where it goes.
