Draining your Air Tanks

How / Where do you do that. I'm having some winter freeze up issues still.  I've got the MC9.

Careful with the Alcohol in your air system it will mess with the rubber parts in the system.

It's ok Dave if you use pure Methyl alcohol people don't like the price and use rubbing alcohol then they pay the price, Bendix sells the Methyl under the name of Air Guard not cheap though

also, Bendix doesnt recommend using alcohol except in some situations.
Thinking about an air drier yet? draining tanks alone doesnt eliminate freezups. Seeing this issue every year at this time.

After 37 years of running the bus w/o a drier - since I installed it I been asking myself - WHAT THE HECK TOOK YOU SO LONG!?

I'm
Pretty sure I have an air dryer in the MC9, no idea how it works or if I should expect trouble free operation bin the cold.

I've run mine in the teens plenty of times, just this year it seems to be freezing up.

 You definitely have to, maintain service on your air dryers.
They are not maintenance free or even low maintenance, any more than any other
part of a complex bus as we most have here in this community of fellow bus owners.
Please do your self a service and learn about the intricacies of your particular unit.
It will serve you well, as long as you service it well. Truly

Even if your air drier is operating fine if you don't maintain cartridge replacement it could be worse than not having one at all.

Of course, just like those Webastos. But they don't need constant service. Or just deal with the moisture/icing issues. Draining tanks removes water, but there is still moisture in the system. We mounted a Bendix AD9 to left of radiator opening behind driver's duals. Cut and hinged a nice factory looking door in the bottom panel for access. Real nice not having water from tanks anymore. Already had a good air compressor that didn't pass oil into system.
