Jeep Air Suspension Failure Test and Refill

Testing if the left front air suspension bag is leaking. Spoiler, it is. I refill the nitrogen tank and use JScan to get it on the road again while I wait for a replacement.

Make sure it has at least 150-175 PSI in the tank. Raise the car to normal ride height and then check it has at least 150PSI in the tank.

Hi Dan, so the r134 fitting itself fits on the car fitting. What about the nitrogen bottle end? Does the ac recharge set fit straight on the nitrogen bottle or do you need to buy adapters?

@@polkypolky8879 I had to buy an adapter to make it work. I think it will depend on your manifold, but I just got mine from Amazon. I think these were the ones I got: EXCELFU 6 Pieces 6015 R134A Brass... www.amazon.com/dp/B07W3X7KBN?ref=ppx_pop_mob_ap_share

Where can i find the fitting you are using for filling the tank? I have the gauges but cant find the fitting and really dont want to spend 275 for a Dorman set if i dont have to.

@@TilerZies My ac gauges came with them, but they are just 134a fittings. So the low side ac line clips right on to the nitrogen tank in the Jeep.

@diydan30 Ahh gotcha. Thank you very much.

I know the app you are using but what OBD2 BT adapter are you using? Looking to refill my system also but want to be sure the adapter I buy will support the air suspension system.

Thank you for the quick reply. I noticed a calibrate option. Ever used it?

[@diydan30]

@@lucastompson8673 yep. It's just to calibrate the ride height back to factory if something has messed up the height. I have a video that shows how to do it but most people don't need too
