🔧 Service Update: QK18K-C Mini X (Kubota Engine) 🔧
At Hobbs Company Limited in Reno, Nevada, our team recently completed a cooling system service to keep this machine running at peak performance. 💪
✅ Removed and replaced the thermostat and gasket
✅ Flushed the entire cooling system until clean
✅ Installed fresh 50/50 coolant mixture
✅ Cleaned radiator and cooling package fins
✅ Repaired a broken floor plate bolt
✅ Tested system operation and freeze protection
📋 What we found:
The old thermostat and coolant had a clay-colored buildup, a sign that contaminants were present in the cooling system. A complete flush restored the system and fresh coolant was installed for reliable operation.
❄️ Freeze protection tested to -15°F
🛠️ Machine hours: 19.1
🧪 Cooling system cleaned, tested, and ready for work
Keeping up with preventative maintenance helps extend equipment life, reduce downtime, and avoid costly repairs.
