Diesel Engine Troubleshooting – Solution here:
Engine Overheating Under Load
- Check the air flow to the rad. Be sure it isn’t blocked by bugs no matter in good or bad weather.
- Check to be sure all axles are rolling freely. Therefore, be sure there are no brakes or tires dragging.
- Check the engine fan and belts to be sure they are operating properly.
- Check outside air temperature. If the air temperature is hot while you’re driving, gear down.
- Turn off the air conditioning on steep grades in hot weather. This will help keep the engine cool.
- Check the oil and coolant levels when the engine is cool. Check for leaks.
