Prevent Engine Failures
Approximately 50 percent of preventable engine failures can be traced back to problems in the cooling system. Advanced coolant testing can be used not only when trying to detect the root cause of cooling system issues, but can be added to testing anytime to help make sure the cooling system is working correctly before issues arise. With regularly performing advanced coolant testing on the cooling system early, concerns can be addressed before a snowball effect of corrosion, loss of heat transfer and ultimately, engine failure occurs.
Advanced coolant testing will involve Ion Chromatography, or “IC” testing. The IC test detects degradation acids that can form naturally as the glycol breaks down with age or may form due to issues with the cooling system. The IC will also detect contaminates, chloride and sulfate that may have entered the system without you knowing of an issue. Contaminates found by IC testing can form acids and create corrosion to the system rapidly. Once degradation acids form, the glycol will continue to break down, creating more and more acids that can cause severe corrosion of the cooling system components and will lead to engine failures. Two of the most common issues seen on the engine side due to issues with the cooling system include exhaust gas recirculation (EGR) failures and oxidized oil, shortening the life of the oil and increasing wear contamination.
Performing advanced coolant testing regularly will also let you see trending results. This will help indicate possible issues such as air leaks, combustion gas leaks, hot spots or even electrical ground issues. With the ability to trend results, an increase in contaminates or degradation acids would indicate an issue or issues are occurring in the system.
