Milemarker Type S Posted November 22, 2007 Share Posted November 22, 2007 A friend has just bought a 1992 200tdi 90. We found loads of air in the power steering system (four bolt box)- foaming in the reservior. I have tried the usual bleeding process (bleed screw on top of box open and lock to lock etc... fluid everywhere and loads of air out. Closed bleed screw- fluid still foaming in reservior... Repeated bleeding process... twice... still foaming... Whilst doing also noticed that someone had put on a tiny narrow power steering belt which was slipping slightly- replaced with correct size one- not slipping any more. Returned to original problem... still foaming and now occasionally large bubbles of air appearing... There appears to be far too much air appearing at the reservior for it just to be trapped in the system and I can only think that it is being drawn in somewhere?? Any ideas anyone??? We don't really want to start buying new bits not knowing where the fault lies... Shrek Quote Link to comment Share on other sites More sharing options...

Milemarker Type S Posted November 26, 2007 Author Share Posted November 26, 2007 Twas indeed the pump... Problem all sorted once we had got hold of a working replacement... 1st Landrover genuine part had a leak on a spot weld on the side of the casing- took us bloody ages to locate where air was still getting into the system- until we turned off the engine and fluid bubbled out of the tiny hole... 2nd Landrover genuine part was very stiff to turn- when the banjo bolt was taken out we found the whole pump was rusty inside! 3rd Landrover genuine part... fitted and bled itself within minutes... Thanks again Shrek Quote Link to comment Share on other sites More sharing options...
