Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

Pop your hood with this lever here. Find the safety release and pull it up. Prop your hood up just like that. Remove this trim piece. There's three clips: here, here, and here. The trick to these is you just push them in with your finger like that. They'll go in a little bit. Then you can pull this right up. Put that off to the side.

Remove the five clips on the top of the bumper right here, and then two more on this side. You can use a plastic trim tool from just to pull these up. Get under here, and pull up like that. Take a ratchet and a 10mm socket and remove these two bolts. These feel a little bit rusty, so I'm going to use some rust penetrant. You definitely don't want to break these, so you might want to tighten it a little bit. Let the rust penetrant work itself in the threads, then loosen it back up very carefully. When you feel it get real tight, I'll tighten it back up. Repeat this process until they're removed.

We're going to raise and support our vehicle. We have a two-post lift, but you can do this in the driveway on the ground. There's a series of 10mm bolts along the bottom edge of the bumper. We're going to soak these in rust penetrant because they look pretty rusty. Now you can remove those six 10mm bolts. These also have a spot for a Phillips, but a 10mm is going to be easier. There's three clips just like the ones on the top of the bumper: one here, one in the center here, and one on this end here. You remove those.

Over on the driver side you can pull this little panel down. Before we remove the bumper, we want to disconnect this harness here. You want to push in on this lock here, pull down, and disconnect that harness. In the wheel well there's a 10mm bolt here you'll have to remove and a trim clip here. We'll take a flat blade screwdriver and spin this horizontal, and then use a trim tool to pull that out just like that. Now you can remove the 10mm bolt. Repeat the same steps on the opposite side.

You want to pull the fender liner back a little bit, grab the bumper, and just give it a good tug. If you need to, you can very carefully slide a trim tool in here and just very lightly pop this out just like that. It'd be helpful to have somebody to hold the other side of this while you remove the other side. Now you can remove the bumper.

Here's our washer bottle. We've removed our headlight so it's easier to see everything. We've also peeled the liner back here. You can find the two bumps on the backside here and here. We're going to push in the tab on this connector and pull it out. To drain the bottle, we're going to use this pump right here because it's closer and easier to get to. This will make a mess. Have a bucket handy and just try and catch as much of this as possible. You want to just pull this pump straight out. It's going to take a little wiggling. It's in a rubber grommet, and they can be stuck in there pretty good. Just let that drain.

Take your hose here. Try and twist it off. These might be a little stuck on, so you can sneak a pick in there, try and break it free. Twist it. There's your pump. Be sure to note which hose this came off of. They're indicated with colors up here. It's a good idea to do these one at a time, but the procedure for this pump is the same as the one back here.

To reinstall the pump, put the hose back over. Might help to remove this grommet and install that first. Then install it into the bottle first just like that. Now you can take your pump and face the electrical connector up like it was before. Press that in there firmly. Need to wiggle it around a little bit just like that. Reinstall your electrical connector till it clicks. It's reinstalled. If you removed any clips to make this easier for yourself from the wheel well, you can reinstall those now. Before we forget, we're going to go ahead and fill our washer fluid. We use the clean bucket so we can reuse the washer fluid. Done. Should reinstall your cap.

Reinstall your bumper. Line it up on the top. Hold the front. Line up the edges. Just snap them back into place just like that. Push your fender liner back into place just like that. Make sure this clip goes back in at the same time. Reinstall this piece. Just push it into place. I'll reinstall your 10mm bolt. Repeat these steps on the opposite side.

Reinstall your clips on the top. Just make sure these are pulled out like that. Push the base in and pop the top on. There's one in the center here, and two on each end. Reinstall your two 10mm bolts at the top here. Lay this piece back where it was. It was over this rubber gasket. Line it up. Push your trim clips out. Might help to have something hard to push against. You want them to be like that. Feed those in.

Reinstall the three trim clips on the top. Reinstall your connector for your turn signals. That will click. Feed this back up here like that. Reinstall your bolt here and your trim clip there. Now you can reinstall the rest of the bolts and trim clips on the bottom of the bumper. Close your hood, and you're all set.
