⚠ Excavator Troubleshooting & Maintenance Spotlight

Fault & Solution: Caterpillar 312 Engine Overheating

If your Caterpillar 312 excavator experiences a sudden rise in coolant temperature, the primary cause is often a stuck or failed thermostat, such as the 15531-73017. Solution: Replace the old thermostat with our high-quality unit. Always inspect the radiator fins for blockage and check the Fan Cooling motor for proper function during the replacement process.

General Engine Maintenance Scheme

Regular maintenance is key to preventing major engine failures. Always use genuine or high-quality Engine Bearing and Gasket Kit components. Schedule a routine oil analysis, and adhere strictly to replacement intervals for the Piston Ring Set 4HK1 Isuzu and turbocharger, especially in demanding applications like the Cummins QSM11. Preventative care ensures maximum uptime and longevity for your Yanmar or Weichai powered equipment.
