LUBRICANT SPECIFICATIONS
Inspection
NOTE
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 & filter.
CAUTION
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.
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.
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.
Do not mix different fluids.
