Engine Coolant Analysis *
Cooling systems remain an important yet often overlooked component of engine health. Coolant can be exposed to contamination, dilution, and oxidation. Our laboratory analyzes the following:
| PARAMETER |
ACCEPTABLE LIMITS |
| pH (s.u.) |
8 to 10 |
| Reserve Alkalinity – mg/L |
> 9 |
| % Ethylene Glycol |
30 to 60 |
| Chloride – mg/L |
< 200 ppm |
| Nitrites – mg/L |
800 - 2500 mg/L |
| Total Hardness – mg/L |
200 mg/L max |
| Color |
Dependent on Base Sample |
| Appearance |
