How to Install the Curt Trailer Hitch on a 2015 Mazda 3


Speaker 1: Today on our 2015 Mazda 3, we're going to be taking a look at, and showing you how to install the Curt Class I custom fit trailer hitch receiver, part number C11377. So here's what our hitch is going to look like. It is going to sit right below the bumper, and the cross tube is going to be visible. Now it's a Class I hitch, so it's going to give us that inch and a quarter by inch and a quarter receiver tube opening, which is going to be great for bike racks and some cargo carriers.Now the way we're going to mount any of those accessories is going to be through the hitch pin hole here on the side. And it is going to accept a standard half inch pin and clip. While they're not included in the kit, you can pick them up here at etrailer.com.

Now as far as the safety chain connection points go, it is going to be a plate style welded to the bottom of the cross tube and the receiver tube here. And as you can see, we're going to have plenty of room to get most hooks on and off.As far as weight ratings go, our hitch is going to have a 200 pound tongue weight, which is the maximum downward force at the receiver tube. It's also going to have a 2000 pound gross trailer weight rating, which is the amount it can pull, including the trailer and everything we have loaded on it. Now, if you do plan on doing some light duty towing, there is some draw bars that are specifically made for our hitch, and you can find them here available at etrailer.com.And also with those numbers in mind, you always want to double check your Mazda's owner's manual and never exceed the manufacturer's recommended towing weight. Now Curt does recommend using a safety strap when carrying any non trailer loads, such as a bike rack or cargo carrier.

Like to give you a few measurements, and that's going to help you whenever you're looking at accessories for your new hitch. From the center of the hitch pin hole to the outermost edge of the bumper, it's going to be right about three inches.That measurement's going to come in handy when you're looking at folding accessories, to make sure you have enough clearance, and it doesn't come in contact with the rear bumper. From the ground to the inside top edge of the receiver tube opening, it's going to be right about 11-1/2 inches. At that height I would definitely recommend a bike rack, or a cargo carrier that has a raised shank, that way we have a little bit more ground clearance. So now that we've seen what our hitch looks like and gone over some of the features, let's show you how to get it started.To begin our installation, we're going to come to the very back of your Mazda, and right at the bottom of our bumper here, right by the exhaust hanger, and the exhaust tip, we're going to have this little section right here where it kind of tapers off, and it comes back.

We're going to have to trim this out just a little bit. And the easiest way to do that, is if we just come right to where it tapers down. We're just going to make a straight line going towards that first hole and then straight down. So we're just going to cut this small section out right here.That's going to make room for our hitch to go into place. Now, whatever you cut this, you can use whatever you have available.

Going to be using a pair of tin snips. Again, we're just going to cut pretty straight line going up to that flat section. Then we'll just cut straight across. We can come back and clean off that marker with some rubbing alcohol. And we're going to cut out that same section on the other side as well. And this site isn't going to have a reference point because it's not going to have the same holes on the bottom, but we're going to want to make that cut about an inch and a half, and again just make it even with this section before it drops down.So if we move underneath right behind where we cut, we're going to find the bottom of our frame. Now we're going to have a large hole towards the very back. If we move forward, we'll have two more smaller holes that are going towards the exhaust hanger right here. Our two mounting locations are going to be the one in the middle and the very large hole towards the back. We'll start by taking our pull wire, and I put a slight bend on the end that has the coiled end on. I'm going to put it into that middle hole, and start feeding it back towards the large hole. And you may have to reach in, kind of help guide it out a little bit.But once we have the coiled end of our wire out, we're going to take a square hole spacer block, slide it over the coiled end. I'm going to go ahead and push it into the frame. We're going to take one of our carriage bolts, and we're going to thread it onto the end of the coiled wire. You're going to want to push both pieces of hardware into the frame. We'll pull on the tail until the bolt drops through that spacer block. For the rear mounting location, it's going to be a little bit different. We're still going to take our pull wire. We're going to slide our square hole spacer block over the end. Then we'll take our carriage bolt and thread it in place.So this time we're going to feed on our bolt first, then our spacer block, pushing it all into the frame, until that bolt drops back down through. And we're going to repeat that on the other side as well. Now with an extra set of hands, we're going to raise our hitch into place. Just want to make sure you feed your pull wires through the top of the hitch before you get it up there. Then we're going to lift our hitch up, until the bolts will drop through. Then we can remove one of the pull wires.And you want to make sure, on each side, you get at least one of the flange nuts in place at least hand tight so the hitch will support itself. And with our hitch supported, we'll remove the remaining pull wires and put the rest of the flange nuts in place. We're going to come back with a the 3/4 inch socket and I'm going to snug up all my hardware. Finally, we're going to come back with that same 3/4 inch socket, and we're going to torque all of our hardware down to the specified amount in the instructions. We'll be sure to repeat that for all of our remaining hardware.That'll finish up your look at the Curt Class I custom fit trailer hitch receiver, part number C11377 on our 2015 Mazda 3.
