Leveling Valve, Leak Test
VN, VAH, VHD, VT
FSB 728-005, Leveling Valve, Leak Test
(May 2019)
Some Volvo VN, VAH, VHD, VT trucks built from July 6, 2015, and equipped with Barksdale
suspension leveling valve may experience air leaks from the leveling valve after the vehicle
is parked (Shut Off) for more than 10 minutes. Air can continue to be released through the
exhaust port of the valve for up to 10 minutes. This is considered a normal function of the
leveling valve and could be misdiagnosed as an air leak. To conduct a proper assessment of
the leveling valve, follow the test and repair procedure outlined in this Field Service Bulletin
(FSB). Fitting kits and leveling valves are available if any valves or fittings show signs of
leakage and require replacement.
