air leak - part identification

olivier · 11-21-2011, 02:49 AM

hi there
I need some help to identify a leaking valve on my Holiday rambler endeavor.I join a picture of it. Basicly when the coach is parked I ear a ''psstttt'' from this valve and after several hours airbags deflate.
So if anybody knows where to find this valve on the web or the name of the manufacturer it will be very helpfull! (I'm in france!)
thanks
Oli

The part in the picture, which is highlighted, is more than likely a air muffler attached to height valve. Your problem is the height valve is bypassing air thru the valve. You did not mention the year of your coach. Also when i magnified your picture I noticed the bottom of air bag ( air spring) looks pretty old by the cracks in the bottom section.

Looks the same as my leveling valves. When I am parked unlevel in just the right position, mine will pass air, trying to level, until the air tanks empty. That is normal. After moving the MH to a more level location, it don't happen.

As to where to get a new valve, I would suggest Freightliner, assuming that is who made the chassis.

thx Tim52 sorry for the confusion but I dont talk about the muffler.
But anyway you answered :it s a height valve.
The coach is 1999.
Yes the air bag sound old but no leak. Do you thing to change the airbags will add some comfort? Is it Dunlop the airbag manufacturer?

And thx Wizard but anywhere I park the coach it's always this valve wich leak (the front left) It's not easy to contact freightliner by the phone from France.
So Have you guys any idea where to find this HEIGHT/LEVELING VALVE?
Thanks again guys

Maybe try here: Freightliner Motorhome Chassis ? RV Chassis
Not sure but maybe customer support may be able to help.

It's a standard truck air suspension part. Most any truck parts shop would have it, e.g. a NAPA store that handles trucks as well as cars. Most larger cities have places that specialize in truck chassis/suspension repair. Or try a Freightliner dealer.
