International prostar 2009 leaking air

Check all the valve splitters up against the firewall in the engine bay, dishsoap in a bowl of water is a big help- I had two of those go while I had a Prostar for under 2 months.

 

Chock your wheels, and release your brakes and check if you can hear anything.

 

Also, put your trans into high range when parked to see if something is leaking with the shifter.

 

ProStars are always leaking air! We had 6 that all leaked down.
Good luck but it does need fixed.
My seat was the first thing to leak....truck had 20k on it.....lol!

 

My 2013 leaks in high range. Just started tonight. Is that a big job to fix. Heavyd

 

It depends where and what is leaking. Maybe just a quick connect fitting. Can you pin point where the leak is?

 

It was in between the to rubber boots. Line rubbing on the bolt.

 

That is actually a common spot. They give a lot of extra line and it bunches up at bit in that area. Should be an easy fix with the quick connect fittings.

 

I drive an '07 Volvo that loses air when not running. 2 shops have looked at and have found nothing.
