How to Install the Air Lift Air Helper Springs on a 2012 Toyota Sienna

Today in our 2012 Toyota Sienna, well be installing the AirLift 1000 Air Helper Springs, part number AL60732. Before we do, were going to go ahead and test the manufacturers suspension system. First, well go ahead and measure the manufacturers right height. This is 29-3/4 inches. Next, well go ahead and install approximately 765 pounds into rear of our vehicle loading it down. Now, our current right height with the weight installed is 27-1/2 inches.

Now, well go ahead and run the vehicle over our test course. As we go through the solemn course, the excessive weight allows for a lot of body roll, and it will have a reduced steering response. As we go over our bumps course, it can be a bit rough with the excessive weight.Along with the body say, we make it a good application for our new airlift system. Now, well go ahead and install the airlift system. Now with our airlift system installed and our 765 pounds weight in the vehicle aired up, brings our new right height to 28 inches.

Now, well go ahead and repeat our same test course. As we go back to the solemn course with the airlift system installed, it really helps control the body roll and sway while bringing back our steering response. As we go over the bumps, it helps control it much better, and its not as shocking with the excessive weight. Now to begin our install, well first go ahead and take the weight off the rear suspension.Now with the rear coil springs extended, well take our airbag and roll it up, flatten it out as much as possible, and reinstall the cap to keep the suction on the bag. Now, we can take the bag, and feed it in to the coil spring.

Quick tech tip, as you put the coil spring in, pick the largest distance between coils to squeeze the bag in position giving you enough room to work the airbag inside of the coil spring. Once we have the airbag in, well then go ahead and remove the plug from the nipple allowing air into the bag and it reforming the shape. Now with the driver side airbag installed, well go ahead and repeat the same process in the passenger side. Now with our airbag in, were ready to start running our airline.Ill start on the driver side. Well feed the airline through the top of the coil spring mount into the coil spring, then well install this spacer which also help protect the airbag nipple.

Next, well install the hose clamp on to the hose. Now, we can simply take the hose and feed it on to the nipple of the airbag; or quick tech tip, to make it easier, we can soak the line in some hot water making it a little more pliable and easier to install. Once we have the hose pushed onto the nipple, well take the clamp and slide it down to the end of the hose which will secure the hose to the airbag. Now, well go ahead and route it towards the passenger side. Keep in mind, when routing your hose, stay as far away from pinch points or excessive heat as possible.Now for this application, well have one inlet and exhaust line. Well use the T supplied with the install kit. Were going to the end the driver side line here near the rear axle on the passenger side. Well be using the AirLift Hose Cutter, part number AL10530 to make sure we get a square clean cut on our hose. Now, once we got the driver side line, well go ahead and route the passenger side. Again, well take our hose, feed it down to the top of the spring, install our spacer block, and install the line clamp. Well go ahead and soak our hose into the hot water. After approximately 3 to 5 minutes, we can go ahead and remove the hose, and install it onto the nipple of the airbag on the passenger side.Well move the spacer down over the top of the passenger side airbag, and then go ahead and continue routing our line. The passenger side hose will now route towards the driver side where we ended the driver side hose. Using our T, well go ahead and hold the lines together, mark the length of our hose, and go ahead and use our tubing cutter, and cut off any excess length. Next, well go ahead and install a hose clamp onto the passenger side hose. Go ahead and take the T-end, warm it with the water, and install it onto the T. Next, well take the driver side hose, and repeat the same process. Now, well take the leftover line, install it into the third port of our T as this will be the inflation and exhaust line that will run to the air valve.Once we have it installed on the T and the clamp emplaced, well go ahead and route the hose towards the rear of the vehicle on the passenger side. To assist in keeping our line up, secure, and out of the way, well be using the Redline Metal Loom Clamp, part number A0500 and a couple of self-tapping screws. Well go ahead and install our loom clamps now. Once we installed the loom clamp and fastener into the frame, well go ahead and route the hose to the clamps. On the passenger side below the passenger side rear quarter panel is a manufacturers grommet. We can remove the grommet and use our utility knife to cut a slice in the grommet that we can pass the hose through.Once we make the cut, well go ahead and push the hose through the grommet and up into the body of the vehicle. Now with all our hose routed and installed, well go ahead and use the zip ties provided with the install kit to secure our hose as necessary being careful not to over tighten it and crush the hose. Then, well go ahead and cut off any excess from the zip ties to clean up our install look. Next, well need to install the heat-shield here on the passenger side to prevent the hot exhaust from doing any damage to the airbag airline. The heat-shield is bendable, so that we can customize it to go around the bend here of the tailpipe. Well go ahead and set our heat-shield in position, and then bend the mounting tabs as necessary.Once we have it formed as necessary, well go ahead and take the clamps, put them onto the pipe, and tighten them down a bit to take up some of the excess slack. This will make it easier to install onto the heat-shield and tighten it down. Now with both clamps in position, well go ahead and set our heat-shield back into place, and install the clamps over the mounting tabs. Now, we can tighten down the clamps. Then, well go ahead and cut off any excess to clean up our install look. Now with our heat-shield secured, were ready to move inside the vehicle. As you can see, our hose is already in the inner quarter panel here. Well go ahead and route it out of the jack storage compartment. Here, well go ahead and remove the vehicles spare tire jack, and tool, and bracket.Now to mount the inflation valve, were going to use a tow-ready mounting bracket, part number 18140, and modify it to our need. Well go ahead and take the bracket, and well predrill our inflation valve attachment point, and enlarge it to the 5/16. Now with that done, well then go ahead and take the bracket, turn it over, and predrill our two attachment points. Once we predrilled the attachment points, well use the self-tapping screws to secure the bracket directly to the body lip just above the frame here on the passenger side. Now with our brackets secured, well go ahead and take our hose, bring it up to the bracket, measure for our length, and cut it as necessary.Once again, well slide the clamp onto the hose, warm the hose in the hot water, and then install the hose on the back and the inflation valve. To secure the inflation valve to our bracket, well install a knot and star washer, put the inflation valve through the bracket, and secure it with a rubber flat washer, metal washer, and then a knot. Now with the inflation valve secured, we can go ahead and reinstall our jack bracket, jack and tools. Were now ready to test our new airlift system. To test the system, well go ahead and put supply air to the inflation valve airing it up. Well check our pressure. Once we have ample pressure, were ready to hit the road. That does it for the install of our AirLift 1000 Air Helper Springs, part number AL60732 on our 2012 Toyota Sienna. .

Ordered AirLift springs from another supplier before finding the EXCELLENT INSTALL VIDEO at your site for my 2011 Toyota Sienna minivan.One suggestion, i did not like your fill valve location and looking in the jack well...surprise....there are existing alignment seam holes in the forward side of the jack well that do NOT require removing jack or any drilling !Might revise that portion of the video, also use a hole punch and NOT utility knife to put hole in drain plug, forms perfect seal.Making install EASIER will attract more buyers, and im going to promote this excellent product ! 7049
