Direct Conclusion
Fouling in aftercoolers and oil coolers directly raises exhaust gas temperature, a common cause of high-temperature alarms in summer.
Judgment Criteria
- 01
Compare inlet and outlet cooling water temperatures with oil temperature. If cooling water is normal but oil temperature is high, check for fouling in the cooler.
- 02
Check coolant flow and water quality; rule out low volume and clogging from suspended particles.
