SLS (Self Leveling Suspension) Fluid Service Kit with Instructions

For 300TD Wagon 190E 16V 500SEL and Other Models up to 1991 with FREE filter for the W123 wagon

Dont neglect this service as many do! I recommend the hydraulic fluid and filter be changed every 30,000 miles. You would not believe how many SLS vehicles I have seen with dirty hydraulic fluid - I mean nasty!  Sometimes I have even found engine oil in the system!  Let me tell you, the system does not respond very well with dirty or high viscosity oil.  ALWAYS use the proper hydraulic fluid made specific for Mercedes Benz SLS suspensions.  If in doubt about what is currently in your reservoir, flush your system and install new fluid and filter.  An empty SLS will require approximately 3.5 liters of fluid to fill it.  You will need 4 liters to thoroughly flush out the old fluid. PLEASE NOTE: The included free filter will only work on the W123 300TD wagon. For the 16V and the SEC the filters are plastc and are cleanable. If your's is damaged you can order separately.
