Groaning sound from steering

[BYprodriver]

Pentosin is required just like RollsRoyces. There is a small & excessively short vent hose attached at the filler neck of the P/S fluid reservoir. The pump gets hot enough to lose fluid out this vent & deposit on top of the engine for eternity. This requires checking the fluid level often & installing a longer vent hose if you want to avoid pump problems & a oily, sticky mess ontop of your engine. While you are there suck out as much old Pentosin as you can & replace with new.
