What's up, guys?
I'm Andy from 1A Auto.
In this video I'm going to show you how to replace the intake plenum gaskets on this
2015 Jeep Wrangler.
If you need parts for your vehicle, click the link in the description and head over
to 1aauto.com.
Take this cover off, just grab underneath, lift up, slide it forward.
All right, so I'm going to take a 10 millimeter socket and a ratchet, and I'm going to loosen
up the negative terminal on the battery.
It's always a good idea to disconnect the battery when you're doing a job like this.
All right.
I'm going to remove this snorkel before I take the intake off.
I don't necessarily have to remove the whole thing, but I'm going to remove it so it's
easier to work on.
Take a 10 millimeter socket and a ratchet.
Take these two bolts out.
Yeah, take a straight blade screwdriver.
Loosen up this warm clamp right here.
And, on this side.
I can grab this, pull it out.
There is a intake temperature sensor right under here.
Just push down on the lock.
Pull the connector out.
Pull this hose off here.
Just slide this out, and out of our way.
I want to disconnect this electrical connector to the throttle body.
I'll just use the street pick.
I want to pull this lock out a little bit...
just like that.
Once that's out...
Should be able to push the lock down and pull the connector out.
This little wire retainer right here, I'll just slide that off, just like that.
Now, I got it off.
Let's pull that out.
I'm just going to use this trim tool right here.
There's some things that are holding the wires on these little wire retainers slide behind
here.
Just pry these off, right here.
We actually sell this tool 1aauto.com.
Pry that off.
And we're going to disconnect this map sensor.
Slide this wiring harness out of the way.
Let's pop this off here like that.
I'm going to get to take this vacuum line off right here.
I'm just going to use these hose pliers.
If you don't have hose pliers, you can try getting a pic behind the front of the hose,
but these hose pliers work pretty good.
Just twist it back and forth and slide it off.
Just like that.
You can try to use regular pliers on it.
Just be careful.
It should be okay.
I'm going to take these two hoses off here.
You can just grab him and slide them off.
This goes to the evap system and then this one goes to the PCV system, so just take a
pic, try to get underneath here.
Oops.
I thought that was part of the hose.
All right, so that slides off like that.
And you might see a little bit of oil in there, that's okay.
All right.
All these are, these hoses are in this bracket right here.
I'm just going to slide these hoses out of the bracket.
All right, that's good.
Just get those out of the way a little bit.
Up on top.
There's two retainers that hold this insulation on, so I'll just use the trim tool and take
these off.
Pop that up.
Pop this one up.
Just use a 10 millimeter socket.
Take this bolt out.
Take that out, set it aside and do the same with this one.
I'm going to grab this installation.
Slide it out.
There's two nuts right here we need to take off and two nuts right here.
I'm going to use a 10 millimeter socket and a ratchet to take them all off.
Try not to drop them.
I'm just going to take a magnet and grab this nut, and there you go.
Got It.
I'll take these two off.
So now I want to take all these intake bolts off.
This plenum bolts.
There is seven of them.
So there's three right here, three right here, and there's a hidden one in the back.
Don't forget that one.
I'm just using an eight millimeter socket and a long extension and a ratchet.
For this last one, I'm just going to use a universal joint.
I just put a electrical tape on it.
That way it doesn't move around as much.
That helps out a little bit.
Can loosen this back one up, slide it up.
That's two bolts I missed.
All right, so there's a little bracket right here, it's two 10 millimeter.
All right, so we'll slide these hoses out of the way.
Actually this hose, I'm just going to disconnect right here or right here.
Grab my hose pliers, just so I can get this out of the way a little bit.
And that one doesn't want to come off there, so try over here.
There we go.
Slide that off, and I can move this out of the way a little more.
You could use a bungee cord and hold that out of your way if you want.
I'll take a 10 millimeter socket and my ratchet.
Loosen these bolts up, take them out.
All right, I got those out.
All right, so the intakes loose as you can see.
So there's the studs that go through this bracket, and that's preventing me from being
able to lift it right here.
And then same right here.
Now you can't take those studs out, because there's these little washers on the backside
that are attached to those studs.
And then over here is the bracket on this side that's preventing me from lifting the
intake.
So I can only lift it so high.
So at this point I'm going to loosen up.
Take these two 10 millimeter bolts out right here, and just use a 10 millimeter socket.
Take this bracket off first.
Take that bracket off.
So this bracket right here with those studs going through is preventing me from being
able to lift the intake right there.
What am I going to do is loosen that bracket up from down below.
It's easier to get to this bracket than the other side.
The other side has a lot more stuff in the way, so I'm just going to use a 13 millimeter
socket and a ratchet.
There's a stud right here.
Loosen this up.
It's either a stud or nut.
So loosen that one up.
And then over here, do the same on this side.
If you have trouble getting your hand in here, you can pull the wheel well out and tried
to get it through the wheel well.
All right, so that's loose enough so that I can pull that off, so I can lift up on the
intake.
I'll try to slide this out.
It's getting caught on something.
Here we go.
And slide it up.
This is the bracket that was causing me trouble right here.
You could just get a pry bar and just pry up on it a little bit.
Not necessarily bend it, but just pry it out of the way while you're trying to lift up
on the intake.
So there's the intake with the gaskets.
You want to be careful in this area.
You don't want to drop any bolts down in there.
Right, now, I'm just going to take a pick can get under the old gasket, slide it up.
If there's some oil in there, you can clean it up.
Just take a rag.
You can always use a little brake parts cleaner.
Just you're better off spaying it on the rag versus spraying into the whole area, because
you don't want it to go down into the engine.
Okay, so that's pretty clean.
Take the new gasket, line it up and just press it down and then we'll do the same with the
other ones.
All right, with the intake, I'm just going to take a rag, just wipe any the oil off the
intake here before we install it.
Make sure there's no gasket material or anything on the edges and surfaces right here.
That looks good.
And take the plenum.
We want to try to fold this underneath this little bracket right here.
So you're just going to have to angle it like this.
Get underneath that bracket.
Make sure all the wires are out of your way.
That's all lined up.
Just wiggle it a little bit.
I'm just going to get these started by hand.
All right.
I'm just going to snug these down with a eight millimeter socket extension and a ratchet.
Now I'm going to use a torque wrench with the same eight millimeter socket and a torque
these to seven and a half foot pounds.
And you have to do it in a sequence so you start with that back one.
That's number one.
Number two is right here, number three is right here.
Number four is this back one.
Number five... number six... and number seven
Okay, I'm going to put the nuts over here, get this one started and this one.
And I'll just take a 10 millimeter socket and a ratchet, snug these up.
That's good.. that's good.
Then I'll take my 13 millimeter socket and ratchet, and I'm going to tighten the two
studs up at the bottom of this bracket.
Now I'll take this bracket and install this.
Slide that in position.
Install the nuts.
Before I tighten those down, we've just got an install these bolts down here.
I'm just snugging these up a little bit.
I don't want these too tight.
And then I'm going to tighten up the nuts with a 10 millimeter socket and a ratchet.
And then I'll tighten these down, snug these down, and then go back and just tighten the
other ones down a little bit.
All right, well that's good, and that's good.
Now we're going to put these two bolts in where this bracket is.
Might have to pull the bracket to the side a little bit to get the holes to line up.
Okay, now let's take my 10 millimeter socket and ratchet and tighten these down.
Just snug, it is tightening into plastics, so be careful.
All right, at this point I'm just going to put this installation back here.
Slide that in position there.
Okay.
We'll take these two brackets.
Get these started.
They look like they're the same bracket and then this one goes right here.
We'll take a 10 millimeter socket and ratchet to snug these down.
Do the same with this one.
And we'll just take this insulation moving forward a little bit.
Push these retainers down.
That's good.
All right.
I'll take this bungee cord off.
Take this pipe.
This is going to go on the bottom.
It's going to lock into there.
I'm going to slide it on over here.
And then lock it in there.
That's good.
This next one is going to go right here and right here.
That's going to slide onto the air box right here.
All right.
This last hose is going to go right here and right there.
This line is going to go right here.
Then I'll take this wiring harness.
This retainer's going to go in right there.
Try to push that in there.
Just like that.
Push this one right here.
Connect this connector, right there.
I'm going to connect this vacuum line right here.
Just push that on.
There's some push retainers on this wire harness right here.
Push those back down.
Make sure that's nice and secure.
Push this retainer right there.
Now, we're going to plug this connector right here, and lock this lock down.
Take this retainer right here.
Slide that right on there.
And we're going to slide this snorkel on.
Get this in position.
Let's connect the intake air temp sensor connector.
Just lock that in place.
I could slide the snorkel on that side, and then slide it onto the air box.
Just like that.
Take a 10 millimeter socket and a ratchet and snug them down.
We're going to tighten up these warm clamps with a straight blade screwdriver, just snug.
Same with this one.
And reposition this hose just like that.
We're going to take this cover.
These two slots are going to line up with those two pieces right there, in the back.
And then these are going to go into these little grommets right there, and just push
it down.
Make sure it's nice and tight.
Now we'll take this negative cable slide on the battery.
Just take a 10 millimeter socket and a ratchet.
Snug this up.
Make sure you wiggle the cable, make sure it's nice and tight.
