  If the starter on your Doosan Excavators does not operate, several factors could be responsible. It might be due to low battery power, so try charging the battery. Check for poor terminal contact and clean and tighten the connections. Other potential causes include a starter switch failure (replace the switch), a starter relay failure (replace the relay), a starter control failure (replace the controller), a faulty wiring harness (replace the harness), a battery relay failure (replace the relay), or a blown fuse (replace the fuse).

  If the engine of your Doosan Excavators runs hot, it could be due to several reasons. Check if the coolant level is low and add coolant if necessary. A faulty thermostat or radiator cap could also be the cause, so consider replacing them. The radiator core or oil cooler core might be plugged, requiring cleaning. Inspect the fan belt for looseness or damage, and tighten or replace it as needed. Lastly, a faulty temperature sensor could be the culprit, so replace the sensor if necessary.

  If the starter engages but the engine doesn't start on your Doosan Excavators, consider these potential causes: the fuel may have gelled due to cold weather, in which case you should replace the fuel. The fuel filters might be clogged, so replace them. There could be water or dirt in the fuel system, requiring you to clean the system and add new fuel.
