Rear suspension leak

[str8pipe]

My car has new compressor, bags, solenoids, and air line. Still losses air when car is off. Everything is good when car is running. Help!!!

Spray everything with soapy water when aired up. Gotta be a leak somewhere. The air fittings on solenoid iirc are pushlock and if not seated fully will leak

Thanks I will try that. Are those O rings in the solenoid air fittings?

I may be stating the obvious or am not understanding the problem, but the air suspension system 'vents' after x amount of time when the car is just sitting...this may be the reason for your loss of air when the car is off.

Yes I agree but she is flat on her butt after a short time of car off. Never did dat before but thanks

I don't know the answer about o rings in the solenoids. Based on your description I think it is an air leak,either bags, lives, solenoids. I don't think this would be it, but check air ride height sensor on watts link to rear axle

Yup changed that too. I'm convinced it's at the solenoid o rings

yes new bags come with new o rings for the solenoids, small for the solenoids, large for where it enters the bag. use soapy water and the leak can be anywhere.

Still checking for leaks nothing yet. Must be super slow.

Is there a check valve in the system maybe after the compressor to prevent it from leaking back down when the compressor is off? Or maybe it's built into the compressor?

Visible confusion...:confused:

I replaced bags and solenoids using aftermarket parts and i went through hell because orings supplied with the Dorman solenoids were the wrong size. I ordered two sets of orings from McMaster-Carr but i dont remember which ones fit.

There was only .5mm different in ID between the two and it made a difference.
