Coolant Test Procedure
3-Way Test Strips
Nitrite concentration is an indication of the overall coolant inhibitor concentration in SLC formulations. These coolants must be tested for nitrite concentration at the regular intervals as listed in Table "Standard Life Coolant". Detroit™ Genuine Fluid Analysis 3-Way Test Strips (or equivalent) are recommended. Use these test strips to measure nitrite and glycol concentrations. Cavitation/corrosion protection is indicated on the strip by the level of nitrite concentration. Freeze/boil-over protection is determined by glycol concentration.
Laboratory Testing
As an alternative to the test strips, a factory coolant analysis program is available through authorized Detroit™ service outlets. To verify coolant acceptability, submit a sample for coolant analysis according to the 'Standard Life Coolant' table.
