Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Clogged radiator fins
- Faulty thermostat
What to do
Immediately stop the 5065E engine and allow it to cool. Check coolant level in the recovery tank; if low, add approved coolant after cooling. Clean radiator fins with compressed air and inspect for leaks. If the problem persists, have the thermostat checked by a dealer.
Hydraulic System Failure
Common causes
- Low hydraulic fluid
- Contaminated fluid
- Damaged hydraulic pump
What to do
Shut down the 5065E and check hydraulic fluid level at the sight gauge. Top up with John Deere Hy-Gard fluid if low. If fluid is milky or dark, drain and replace. For pump issues, contact a John Deere service technician.
Engine Won't Start (Cold Weather)
Common causes
- Faulty glow plugs
- Low battery power
- Thickened fuel
What to do
On the 5065E, ensure the glow plug light turns off before cranking. If the battery is weak, jump-start using proper procedures. Use winter-grade diesel fuel and consider adding anti-gel additive if temperatures are below freezing.
Swing Brake Malfunction
