LUBRICANT SPECIFICATIONS Inspection NOTE If incompatible (insoluble) fluids are mixed in a power steering system, air bubbles can be produced at the interface of the two fluids. This can cause cavitation, which reduces the lubrication between moving parts in the gear. This could result in worn components. Before removing reservoir cover, wipe outside of cover so that no dirt can fall into the reservoir. 1. Check the fluid level; add fluid if required. 2. Check fluid for contamination, discoloration, or burnt smell; correct source of such problems before replacing fluid and filter.
The mixture of two different fluids, although harmless to individual internal components, may initiate a chemical reaction that produces a new compound that will attack seals and other internal components. 5 When adding fluid, be sure to use fluid of the same type. While many fluids have the same description and intended purpose, they should not be mixed due to incompatible ad- ditives. Mixing incompatible fluids may lead to equipment damage. CAUTION Do not mix different fluids. 5-56 Y53-6077-1B1 (03/17)
