It's not the Hydraflush itself that does this, but the effects of the fluid's cleaning action.
The Hydraflush is a special designed fluid to remove the dirt from inside the system. The dirt is caught in the normal LHM oilskin, which is dissolved by the Hydraflush.
You should let the Hydraflush stay in the system for at least some 3200Miles, but never run the car with the Hydraflush for more than 5000miles, since the fluid has less lubricating effects, than LHM.
On replacing back to LHM, the filter reservoir can MUST be cleaned out internally, litterally done by hands & lots of rags. If this is not done, the cleaning effect wo'nt last long, since dirt from the reservoir will then spread out the system again. Also the filters in the reservoir must be cleaned.
NOTE : if these filters have holes or cracks in the fine mesh, they should immediately be replaced !
Besides filtering dirt the fiters also breaks down air bubbles, from the system returning fluid to the reservoir. If these air bubbles are allowed to reach the pump & thereby the system, all kinds of strange faults may be observed.
The LHM (or Hydraflush) is NOT directly related to suspension comfort.
If you're experiencing bumpy/harsh suspension, allways check the wheel spheres, by lightly pressing down each corner of car, when at normal drive height. It should be very easy to press down. If rock hard, the associated wheels sphere is most definately flat.
Allways replace both spheres on same axle, since a flat wheel sphere allways seeks company.
