Air froze

[tknight]

I think my air suspension for the cab is frozen
Rough ride and its leaning into the sleeper seal hope it melts soon befor tearing the seal , that would certainly suck!

It could have. If you can see it look to see if a control rod came off.
Not even sure you would have one.

Control rod is on valve is 2 weeks old, I rapped it with a hammer a few times if its ice is somewhere stuck in that 1/4 line I really dislike those quick plastic plug in lines I'd rather unscrew brass to check for air in lines than break the plastic connections

Try some airline antifreeze. How often do you drain your tanks?

 

[zorry]

You shouldn't have to break the plastic.
If the female fitting has a ring at the edge, it may push back and release the male air line.
Anything can break in very cold weather.

I usually drain once a week and dump my air bags at most pickup and delivery so they're pretty well drained ,I also installed a removable plug in my air tanks to add anti freeze to my system last winter makes it fast but hey it's pretty darn cold right now

Id add the airline antifreeze, this is when its needed, I typically put in in BEFORE its needed if I know the air temps are going down below zero, its saved my butt the hassle of trying to work on it when its -10 outside....

Once again folks:The easy way out if your going to run in this kinda weather..

Haldex

If you have A high quality air dryer you will be good. Bendix AD-9 one of the best Wabco worst.

Agreed the AD-9 is easy to work on and service and a good unit..Think the after market rebuilders could do a little better on the spitter valve/heater element. Seems mine dont make much more then 9 months to 1 year before they stop resetting themselves. But its a easy fix once it starts leaking..
Anti-freeze canister is just a little insurance.
