Default Test drove a 6-sp Atlas AR during lunch. Air system questions.

1. How long does it typically take to go from level 1 to level 2 (lowest to middle)?

2. Is there a good way to diagnose the airbag's condition?

3. The air compressor was a little noisy, is this normal? Like a loud fuel pump in the trunk.

THANKS!

Takes a long time between levels. Probably 30 seconds?

Default Yeah, I went from 1 to 2 and it took probably 30-50 seconds.

At a light. hit the switch, turned right and then it wasn't done until 1 block later.

Default A bit of explaining...

the suspension system is a slow feed air system. The compressor feeds the storage tank. (not the air sprins).

Its the storage tank that feeds the air springs.

The compressor will only come on when the pressure inside the storage tank gets below a certian level.

Re: If the pump is noisy it won't be long before it needs replacing

Default It had been sitting for a bit (maybe a week) and this was the first suspension air change.

when I first got to the car, the front was slammed (I'm guessing from not running). Is this an indication of an air leak in the bags?

It leveled out fine though.

Default Noisy as in I could hear it (and feel it very slightly). It is on par with the sound the air pump

for the door locks makes.

Is that normal? Can you hear a perfectly working compressor?

Default if you hit press the button on dashboard( UP) and you will heard that

pump kicks in, it will take much longer, at least 30s. If the air tank it's full it take only 15s.

Thanks, sounds like it's normally functioning. The pump kicked in as soon as I hit the button.

Default its is likelye a minor leak..

the seals or a tiny worn hole in the spring.

Keep wath on it, park it at the same level and see.
