Air Bags

[LaRolnKat]

I have a 06 HR diesel. I had gas before so I really don't know what would be causing my coach to lean to the drivers side every couple of weeks. I cranked it last weekend and let the air build up and I went look today and it's leaning again. What can be causing this?

You did not mention which HR or whether it has air leveling or not. This is considered normal unless you have air leveling. You can call Monaco, they will say it is normal for the air will leak down in 24 hours or more. You may have a slow leak in a dozen or more possible places that cannot be found by ordinary mortals. Go around and spray soapy solution on all of the air connections especially the air leveling system, height adjusting valves, etc. Check the ride height adjustment as a small lean will cause one side to dump air that will eventually deplete the air. If you park it on a tilting pad it will leak down prematurely as well. I used to worry about where the air went but now I always dump the air and use jacks if I plan to sit for any length of time.

Think we've all had this issue, but suggest you might wanna check your air line right at the fittings, they do rattle loose and slowly leak...also the next time you fully air up and plan on sitting/hanging around turn off your batteries/kill switch..Your coach may try to auto-level itself from external/internal movements/wind, ect., as long as your coach has power connected. Also you could dump your air completely and level off. They all bleed off slowly over time... Happy Rvings.

Simply put, gas coaches ride and sit on springs, and these never change position except when riding down the road.


Diesel coaches ride on air, and the air will slowly leak out of the bags when the coach sits unless you have an air leveling system and it is powered up. It is not a problem for the coach to settle when in storage.

When you stay in an RV park, make your shore connections, then put the slides out, then blow the air, then deploy your jacks. If you have air leveling, it will blow the air on its own.

Had a similar problem on a 2002 Endeavor. The problem was a leaking valve? on the firewall in the generator compartment. I can't remember what the part was called. It was brass colored with airlines entering and exiting. It was about 1-1/2 inches by 3 inches by 1/2 inch. You could hear a slow leak in the area of the valve. Good Luck. I wish I could remember the name of the part
