"Serious heat" being a relative phrase, I suggest that if you quantify it
you will find that the 200 under hood temps are not extreem relative to
either DTE-13M or Pentosin CHF 7.1 max recommended service temps. The
highest temp to which the fluid is exposed occours within the pump, where
the mechanical energy is converted to fluid pressure, and this temp rise is
normally small excepting when max PS force is required (at which times under
hood temps are not max).
IMO, flushing the rack is a pointless exercise, short of its necessity for
rack overhaul. Good only to satisfy ones thin wallet needs. Flushing will
replace the old fluid containing harmless suspended color particles, but
will not remove any larger sediment deposits from within the rack, also
harmless undisturbed. Nothing wrong with reusing the old stuff. BTDT.
