40% of all maintenance problems on diesel engines can be attributed to poor maintenance of the cooling system. Being a mixture of ethylene glycol or propylene glycol with water, coolants can freeze, increase in volume, solidify and crack hoses, radiators and engine metal. Under high temperature, they decompose producing a corrosive acid in the cooling circuit.
Coolants are also vulnerable to contamination. A systematic analysis program is therefore necessary to monitor their degradation and detect wear signs in the cooling units. Please view our April 2011 and October 2011 Newsletters for additional details.
The basic test package for coolants consists of four tests: Elemental Analysis by ICP – pH Measurement – Conductivity and Glycol Percentage. See the March 2014 Newsletter:
| ICP Spectrometric Analysis | pH Measurement |
| Conductivity of Coolant | Glycol Percentage |
| Density | Ion Chromatography |
| Color, Odor, Clarity, Precipitate, Foam | Coolant |
| Total Dissolved Solids | Total Hardness |
