Coolant Troubleshooting Guide
This chart will assist you in troubleshooting coolant failures and was designed to provide a visual reference to indicate these failures and how they may be traced to one or multiple sources for correction. You may also reference what other failures may arise if one or more of the preventative maintenance issues are mismanaged or entirely neglected.
For instance, your coolant emits a foul odor. This failure is traced to poor management of Tramp Oil and pH. You may need to skim tramp oil more frequently (every day is recommended), aerate the fluid (when not in use), and monitor pH levels (once a week) to prevent recurrence.
You may also be experiencing other problems that are caused by the same neglect, such as split emulsions, rust, and skin sensitivity.
