Video Transcript for Trailer Hitch Installation - 2017 Mazda CX-5 - Curt

Speaker 1: Today on our 2017 Mazda CX-5 we're going to be taking a look at and showing you how to install the Curt Class II Custom Fit Trailer Hitch Receiver, part number C12170.Here's what our hitch looks like once we have it fully installed. It is going to tuck up nicely behind the bumper, and all we're really going to see is that receiver tube sticking out. It's a class II hitch, which means it's going to give us that 1-1/4" by 1-1/4" receiver tube opening. As you can see, it has a nice reinforced collar not only giving it that added strength, but a nice clean finished look. All of your accessories are going to mount right here with the pin hole, and it's going to accept a standard 1/2" pin and clip, which they are included in our kit, which is always nice. Our safety chain connection point is going to be a loop style underneath welded to the bottom of the receiver tube, and it's just slightly offset from the pin hole, so it's going to have plenty of room to get most size hooks on or off, and we're not going to have to worry about anything interfering.Your hitch is going to have a 350 pound tongue weight along with a 3,500 pound gross trailer weight rating.

Now you always want to double check the owner's manual to make sure your vehicle can handle pulling that amount of weight. Also, per the manufacturer any non-trailer loads, such as a bike rack, cargo carrier, or anything that doesn't have wheels on it, they do recommend that you use a support strap, and you can pick one of those up on our website using part number 18050.I'd like to give you a few measurements that will help you when deciding for accessories for your new hitch, such as a bike rack or even a cargo carrier. From the center of the hitch pin hole to the outermost edge of the bumper it's going to be right about four inches. From the ground to the inside top edge of the receiver tube opening it's going to be right about 13-1/2 inches. 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 installed.To begin our installation we're going to come to the very back of our vehicle, and just right underneath our bumper we're going to have a plastic panel that we're going to have to remove.

We're going to have one plastic pushpin, one on each side. To remove those, I'm going to take a flathead screwdriver, and there's going to be a little indention on either side, and you're going to want to pop out that center section first, which will release the tension. Then we can pop the rest of the clip out. We'll go ahead and do that for the other one too. Now if we just move towards the center just a little bit, there's going to be square hole right there.

We're going to take our screwdriver and there's going to be a small tab. We're going to push in on that tab, which is going to release the plastic panel, and then we can pull it down. There's going to be one on each side.Now in order to get our hitch in place, we're going to need to lower our exhaust down. Before we do, I'm going to take a little bit of spray lubricant and I'm going to spray down the rubber isolator making it a little bit easier to pull that hanger out. We're going to have one right next to our tailpipe, and then one right behind it.

We're going to have two on each side, so we can go ahead and spray the other ones also. Then you're just going to take a pry bar and your main goal here is just to slide that rubber isolator off of the post here so that we can lower it down. Now that we have one removed, we're going to go ahead and put a strap to support our exhaust so it doesn't fall down all the way. You're going to want to find a sturdy location to put your strap up. Then we can go ahead and work on removing the rest of the hangers. You want to adjust your strap so that you have enough room to get the hitch in between the exhaust and the bumper here, but you don't want your exhaust to hang down too far.If we come to the very side of our frame rail, we're going to see that we're going to have a sticker or some tape on the side. Now that's going to be covering up our mounting hole, so I'm going to take a flathead screwdriver, you can take whatever you've got available even if it's just a utility knife, you're going to want to scrape away all the tape so that we can gain access to that hole. That's going to be one mounting location that we have. That's going to be towards the very back of our frame at the bumper. If we move forward, just right real close to that forward exhaust hanger we're going to have another one that's further up. You're going to want to remove the tape or sticker off of that one as well. Now we're going to have both these mounting locations on both sides of our vehicle, so we can go ahead and do that on the other side as well.Now also on each side of our frame rail we're going to have a wire coming down that has a clip that's put into the side of the frame rail. Just going to take a flathead screwdriver and we're going to pop that mounting clip out. We'll notice that we're going to have a lot of excess seam sealant on the side of our frame. To make sure that our hitch seats up against our frame properly, just take that flathead screwdriver and you're going to want to peel off and scrape off all that excess sealant on the side of the frame. We don't need to take it all off, just want to make it so it's nice and clean on the side. Once you have it all nice and cleaned off and all the excess peeled away, go ahead and do that on the other side too.Now the forward mounting hole towards the front of our vehicle is going to have an existing weld nut inside of it. Now for whatever reason if there wasn't any tape covering that up, dirt and debris and moisture is going to get inside of there, which could cause some problems when we go to thread in our hardware. A quick solution to that is just take a little bit of spray lubricant, you're going to want to spray it inside the hole of the weld nut. Then we're going to come back with a nylon brush, and we're going to make sure to clean all the debris out of there and make sure the threads are nice and clean. We'll do that for both sides to make sure that we can get our hardware in place.Now towards the back of our frame where our rear mounting location is, if we come to the bottom of our frame, this large hole is going to be our access hole. To get our hardware in place, we're going to take our fish wire, we're going to go in through the mounting location, and you're going to want to pull that wire down through that access hole. Once you have it through, you're going to take one of the square spacer blocks and you're going to feed it over the coiled end. Then you're going to take one of the 1/2" carriage bolts and thread it on. Then we can tread each piece individually up into the frame. Go ahead and pull that wire back through so the hardware comes out. Now on some models there may be a weld nut right here. If you do, you don't have to worry about fish wiring this side, but since we don't have one we went ahead and fish wired our hardware through. We're going to do the same thing on the other side as well.If we come to our hitch, we're going to see where our mounting locations are going to be. Now we're going to have to take the 1/2" flat washer, and to make our installation a little bit easier on ourselves, if we come to the inside, you're going to take a small bit of tape, you're going to want to line that washer up with the oblong hole. Then take that bit of tape and we're going to tape it right to the hitch. Now we're going to do this for all four mounting locations. With an extra set of hands we're going to lift our hitch into place. You want to make sure you take that pull wire and you go through the rear mounting location. When we raise our hitch into place, you want to guide that wire through and make sure that that bolt is on the inside of the frame for now. Then you're going to push it behind the bumper. You may have to pull down on the fascia just a little bit to get it in there. You're going to want to pull that pull wire once you have it lined up to get the bolt to come through. It's going to come through the frame and then through the hitch itself.Now on our forward mounting location we're going to be taking an M12 bolt followed by a conical tooth washer. You just want to make sure that the teeth are facing towards the hitch. You may need to grab the receiver tube of the hitch to get everything lined up properly, kind of tilt it, and we're going to thread that into place. Once you have your bolt through, it should support the hitch. We're going to go ahead and pull our bolt leads off. You can either just pull them off or unthread them from the bolt themselves. Then we're going to take a 1/2" flange nut and thread it onto that carriage bolt. Once we have one on each side, then we can work on getting the rest of our hardware in place. We'll go ahead and put the other side in as well. For our 1/2" flange nuts, I'm going to come back with a 3/4" socket and snug them up. We'll go ahead and do that for both of them. Our M12 bolts, I'm going to come back with a 19 millimeter socket and snug those up. Just make sure you get both of them done.We can go ahead and come back and we're going to torque all the hardware down to the specified amount in the instructions. Just want to make sure you get all your hardware torqued down. I'm going to go ahead and spray a little bit more spray lubricant on my exhaust hangers making it that much easier to put it back in place. With our exhaust up, I'm going to go ahead and take that strap down.That will finish up your look at the Curt Class II Custom Fit Trailer Hitch Receiver, part number C12170, on our 2017 Mazda CX-5.

Exactly what I was looking for. Needed a hitch for our Mazda CX-5 only to be used for a bike rack. Good sturdy construction and easy install. 545658

Came just as described and it installed just like the video and instructions! Have not towed anything yet, but looks good installed, just like the pictures show. I received the hitch surprisingly fast, and customer service was very friendly and helpful. 476359

Install wasn’t quite as easy as they make it look in the video. Took me and a friend about 20 min to get the hitch in position to feed the bolts through. You have to pull pretty hard to get the plastic bumper to flex around the hitch. But once it’s in position, it fits and looks great! 498948

Great product. Good price. Easier to install than I thought it would be. Including the fish wires was awesome! I do not think I could install it without them! With them, install went great! Instruction video was also a great help. I would recommend this for light duty applications, such as bike racks, and pulling small utility trailers. 580483

Hitch and other ordered products arrived quickly and in good condition. Hitch was carefully packaged to prevent damage. Well done. Have not had time to install yet and will be doing this solo. Install package looks very well thought out, instructions are clear, accurate, and well illustrated. Note: I ordered some etrailer brand rubber hitch plugs (one for another car with 1.25 inch hitch) and I think these are well worth the low cost to give the job a more finished look and maybe keep grit out of your hitch when you back into dirt piles. If possible, I will update review after the install. So far I've spent about an hour gathering tools, checking kit for completeness, and removing the tape from holes in frame. My car lacks the rear plastic strip that is on some CX5s. The forty minutes for novice install might be a tad optimistic unless that's just to toss up the hitch and bolt it, not counting related activities. 656770

First time self installer without professional equipment (car lift, power tools, etc.) should anticipate more than 20-40 minutes installation time. Well built, quality product that fits perfectly. I ordered the hitch through their customer service. Vanessa was very knowledgeable, answered all my questions and was helpful in making the right choice. The hitch arrived promptly. The etrailer video installation instruction was very helpful which I followed over the factory instructions. I installed the hitch in my garage, on the floor and by myself which took about 90 minutes. I would recommend having a helper which would likely reduce the installation time. 543002

My Curt Hitch is perfect in fit, finish and application. It solves the problem of transporting and launching a 15' Alumacraft fishing boat. etrailer's price and advice are better by far than others, and include excellent instructions plus videos if needed. This is a well engineered product sold by very detail orientated professionals. I can honestly say that I'm thrilled to find etrailer and highly recommend them. 517252

  • Choosing Between Class II and Class III Hitch for 2018 Mazda CX-5
  • When a choice of hitch classes is available for any vehicle we always recommend going with the higher-capacity option since the cost is usually about the same. You can refer to the linked hitch article for details about the various types of hitches offered. In the case of your 2018 Mazda CX-5 we have both 1-1/4-inch Class II hitches like Curt # C12170 and 2-inch Class III hitches. I recommend the 2-inch Class III Draw-Tite hitch # 76138 since it has the highest weight capacity, the best...

  • Class II Hitch Availability for 2016 Mazda CX-5
  • It's a warranty situation for the Curt hitch. It's not that the Draw Tite is necessarily stronger than the Curt it's just that they approach the idea of carrying a non-supported load more cautiously than Draw Tite. The only thing is that for your 2016.5 Mazda CX-5 there is only the Curt hitch part # C12170 that is confirmed as a fit so you would have to use the # 18050 with a bike rack. Realistically Draw Tite will eventually have a hitch fit for your vehicle, but at this time we are...

  • Ground Clearance for Curt Class II Trailer Hitch on a 2019 Mazda CX-5
  • When we installed the Curt Trailer Hitch Receiver # C12170 on a 2018 Mazda CX-5 we found that from the ground to the bottom of the receiver measured about 12-1/2". I don't think it will be much different for your 2019 Mazda CX-5 but I went out to the warehouse and found that from the center of the rearmost bolt hole to the bottom of the safety chain loops measured about 8-1/4". You can use the attached diagram to take some measurements on your CX-5 to see how far down the trailer hitch...

  • Both Curt # C12170 Class II hitch and # C13315 Class III hitch custom designed to fit the 2017 Mazda CX-5. Both hitches are designed to fit up and behind the bumper of the CX-5. The main difference between these two hitches is the Class III hitch has higher towing and tongue weight capacities and a 2 inch hitch receiver opening. The Class II uses the 1-1/4 inch receiver opening. I recommend using Class III hitch because the 2 inch receiver opening will give you more options for hitch...

If you plan on doing some towing I recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop.

  • Trailer Hitch, Wiring, and Brake Controller for a 2015 Mazda CX-5
  • There are some Class III trailer hitches available for your 2015 Mazda CX-5. The most popular option is # C12170. But even though the hitch is rated for 3,500 gross trailer weight, your CX-5 is only rated for 2,000 pounds (see the towing section in the owner's manual for additional information) so you will be limited to 2,000 pounds gross trailer weight and up to 300 pounds tongue weight. This works out since the trailer you are buying weighs less. Like you said, none of the hitches...

  • What is the Difference Between a Class II and a Class III Hitch?
  • The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to 3,500 lbs in GTW and up to 525 lbs in TW. Class III, on the other hand, have a 2 inch receiver and have up to 8,000 lbs GTW and 800 lbs TW. I will attach a help article that goes in to more detail for you.
