6.9 Suspension Fluíd Capacity
« on: 03 February 2020, 10:17 AM »
Hello,

Does anybody know the total capacity of Suspension fluid that needs to be placed in the 6.9 suspension fluid reservoir?

Additionally, mine is in the low mark.  Does anybody know how much I need to put in to each the High mark on the dipstick?

Thank you for the support.

Best regards,
Angel

As per service manual:

Total cap: 5.8 litre
Reservoir min: 2.6 litre (low mark on stick)
Reservoir max: 3.6 litre (high mark on stick)

Use this as good opportunity to flush out the system complete, and change out the filter under the pressure regulator.  Good and cheap insurance ;)

Hell Daniel,

Thank you very MUCH for this information.  It is very helpful.

Regarding the filter, I replaced it two years ago when changed one of the hoses. Should be fine here.
