Air tank water drains

For all you diesel Tradewind experts..dumb question time. I have spent quite a bit of time crawling under and around by 03 TW looking for the air tank water drains. Where are they or does the Spartan chassis model not use them (have auto drains)?

On my Freightliner chassis, the "pull" lanyards are located in the left and right front wheel-wells. Find the air tanks and see if you have vent valves on the bottom with wire pull lanyards that go somewhere. Rook

That what I had seen before on tractors but they do not appear to be present on this beast.

If you have auto drains, they will back about 4 inch square, under the tanks, with what looks like a tire valve core in the center. Push it in, and stand aside.

If nothing, look for 1/4 inch pipe plugs in the bottom of the tanks. If you have 2 tanks, good chance1 is a double tank and will have 2 of the plugs. That's where you can put drains.

You are describing close to what I see on the tanks. It appears to have square shaped "solenoid" on each tank but I do not see anything that looks like a value stem.
I do have a air output (for use on tires,etc) at the front of the coach by the genset. I have drained it down before but have never had any water come out. It is plumbed directory into the tanks, ie seems to bypass drier.

No, you got that backwards.

Any air is already run thru the the Air Dryer, before entering the tanks.

There are a few different style water ejectors. Try finding a brand name, and Google it.

A way to check would be to run all of the air down, remove one of the electors, preferable the wet tank, one and see if any water and oil drips out. The wet tank is the one that the big line, from the air dryer, goes to.

If that tank has 2 electors, remove the one closest to the air dryer line. It's a dual tank.

Be sure the air is drained.

Good luck
