This is a late model 4000 diesel with the combined power steering reservoir/pump.
Can't find anything in manual that says what the correct fluid level should be.
There is a cap on top of the pump and I can see the filter? screen but no fluid visible.
System works fine, was just doing some maintenance.
also I don't know what the previous owner used for fluid...ATF or power steering fluid
if I can suck/drain some out can I tell, visually, which it might be?
