Technical Specs
You install SIERRA
just as you would any other antifreeze. Drain the old coolant from
your engines cooling system...flush it thoroughly with water,
refill with a 50% SIERRA Antifreeze and water mixture.
Dispose of the old coolant and the
rinse material properly and in accordance with state and local
regulations.
Test the freeze point of freshly
installed SIERRA with SIERRA Freeze Point Test Strips or a SIERRA
Floating Ball PG Hydrometer.
For best results, use SIERRA
Radiator Safety Flush to safely remove rust, scale and deposits
from your cooling system before refilling with SIERRA Antifreeze.
