How to Install a Trailer Hitch on a 2006 Pontiac Montana SV6

Today on this 2006 Pontiac Montana, we will be installing Curt hitch part number 13336. OK, we are underneath the vehicle and the first thing we have done is gone ahead and lowered the spare tire. Get it out of our way. We are looking at the passenger side frame rail. We can go ahead and point out the mounting holes we are going to be using for our trailer hitch. You can see here at the bottom of the frame, we have two bolts holding the exhaust hanger onto the frame. We are going to lower those down and those are going to provide our two rearmost attaching points. And just forward of that, there is a fascia support that is held in with another bolt. And we are going to remove that bolt as well and that will provide our third attaching point. If you go to the vertical side of the inboard part of the frame, you can see we have a hole here. That is going to provide our fourth attaching point. At this location, we are actually going to fish wire a 7/16 carriage bolt, along with the carriage block, into position. 0:42

And that is basically going to be the same on the driver side. However, on this particular vehicle, we do have the load leveling compressor here with a large bracket. And it is just being held in with just one of the bolts. The second weld nut is underneath the bracket. And we are actually going to trim the bracket like so, so that it will provide the clearance needed. The first thing we want to do is go ahead and remove all of the bolts that we had pointed out previously and then we will go ahead and get started installing our hitch. With the bolts removed, I am going back over to the driver side and we are going to go ahead and lower down the load leveling compressor. If you go through the outboard side over here, you can see we have two screws holding it into place. You can see with the compressor lowered down, the second weld nut is now visible. You do want to support the compressor after removing the nuts off of these threads here, because it will want to fall down and we do not want to damage it. The next thing that I am going to do is go ahead and trim out the load leveling bracket. Next, we just need to take off this area right in here. And then again, that is going to provide clearance for the head of the bolt that is going into the second weld nut. 1:46

With the bracket modified, I am going to go ahead and reattach it to the two outboard studs. So with the compressor back up, we can go ahead and put the hitch in position. Over on the passenger side, we will go ahead and slide it into place and we will attach it to the forward most attaching point. You just want to make sure that you put your bolt in through the fascia support and then up through the hitch and the weld nut. Over here on the driver side, we are going to attach to the middle weld nut and all of the weld nuts are going to be getting 10 millimeter bolts, along with the conical tooth washers. OK, we can go ahead and put the exhaust bracket back up into place next. It is going to realign with the holes in the hitch. Some models may have a different exhaust bracket and in that case, you may have to use the tab that is welded onto the hitch right here. With the hardware in the bottom of the frame loosely installed, we are going to go to the inboard side now, where we are going to attach the hitch to the frame. We are going to take the 7/16 bolt leader and feed it out through the end of the frame here. There is a nice, large hole. It is enough room for us to get our hardware into place. We will next take the block and slide it onto the bolt leader. And then take our carriage bolt and wrap the threads of the bolt leader around the threads of the carriage bolt and just feed it inside the frame. And pull it into position. To the bolt we are going to add the flange hex nut. OK, we want to do the same thing for the driver side hole. 2:57

And now that we have all of the hardware in place, we are going to go back through now and torque all of our bolts down. You want to verify with the directions the specific torque rating for each of the bolts. Alright, and now that we have all of our bolts torqued down, we just want to make sure we put our spare tire back into place and our installation will be complete. Now that we have our hitch installed, we are going to go ahead and give you a couple of final install dimensions that will help make choosing your hitch accessories a little bit easier. From the top of the receiver tube opening to the ground is going to measure 13-3/4 inches. And from the center of the pin hole to clear the rear edge of the bumper is going to be approximately 7 inches. This will conclude the installation of Curt hitch part number 13336 on a 2006 Pontiac Montana.
