LHS versus LHM Hydropneumatic suspension
lhm reservoir , green suspension sphere in citroën xantia
to overcome these shortcomings of lhs, citroën developed new green fluid, lhm (liquide hydraulique minéral). lhm mineral oil, quite close automatic transmission fluid. mineral oil hydrophobic, unlike standard brake fluid; therefore, gas bubbles not form in system, case standard brake fluid, creating spongy brake feel. use of mineral oil has spread beyond citroën, rolls-royce, peugeot, , mercedes-benz, include jaguar, audi, , bmw.
lhm, being mineral oil, absorbs infinitesimal proportion of moisture, plus contains corrosion inhibitors. dust inhalation problem continued, filter assembly fitted hydraulic reservoir. cleaning filters , changing fluid @ recommended intervals removes dust , wear particles system, ensuring longevity of system. failure keep oil clean main cause of problems. imperative use correct fluid system; 2 types of fluids , associated system components not interchangeable. if wrong type of fluid used, system must drained , rinsed hydraflush, before draining again , filling correct fluid. these procedures described in diy manuals obtainable automotive retailers.
the latest citroën cars hydractive 3 suspension have new orange coloured lds hydraulic fluid. lasts longer , requires less frequent attention.
