Here's the items you'll need for this repair: flat blade screwdriver, 15mm wrench, 15mm socket, ratchet, socket extension
Loosen the hose clamp just after the mass air flow sensor. This is going to be the second one back from your air box. We'll do this using a flat blade screwdriver. Wiggle and twist the boot to release it from the mass air flow sensor. You may need to use your screwdriver to help peel it back here. These tend to get stuck on pretty good. We'll also remove the one at the throttle body. We'll need to disconnect the hoses from their clamps here. You can either try prying it out there, or there's also a little clamp at the bottom here that you should be able to compress, pop loose with a flat blade, and remove the intake runner from the vehicle.
We've removed some things like the radiator fan and the fan shroud to make it easier to show you what's going on, but you shouldn't need to do this if you're doing this job at home. Before removing your serpentine belt, make sure your vehicle has a belt path diagram under the hood somewhere. If this is missing or faded, you can just draw another one onto the plastic with something like a paint marker. Using a 15mm wrench on the tensioner, rotate the nut clockwise to slack the belt. Pop the belt off of whatever pulley is easiest for you to reach. Let the tension off the pulley and remove your serpentine belt.
Install the belt over the front grooves of the harmonic balancer or crank pulley. Bringing the right side over top of the pulley. We'll then go over top of the water pump and loop under the power steering pump, over the alternator, under the idler pulley. I'll keep this piece in my hand. Make sure that everything is seated because this one's kind of tight and you're going to want the room. Using my 15mm wrench, we'll take the tension off of the tensioner pulley, slide the belt over, double-check that our path is right, all of the belt is properly seated, and then let the tension back on.
Reinstall the intake tubing. It's easiest to set it onto the throttle body. Reengage the hoses into their clips and then get the boot over the air box. Then tighten down both clamps with a flat blade screwdriver.
