  Jason AlexanderAug 15, 2025
  If your Daedong Engine overheats, there are several potential causes. First, check the coolant level and add coolant if it's low, repairing any leaks. Inspect the fan belt for looseness or breakage, adjusting or replacing it as needed. Ensure the anti-freeze concentration is correct by adding water or replacing the coolant to achieve the proper mix. Clear any dirt and debris from the radiator core and radiator guard. Also, check the oil level and add oil if it's low, and check the fuel injection timing, adjusting it if necessary. Replacing the fuel with the clean fuel of the proper type and grade may also help. Other potential issues include a defective radiator cap or thermostat, a leaking head gasket, or unsuitable fuel.

  If your Daedong Engine suddenly stops running, first check the fuel level and refill if necessary. Then, inspect the fuel system for leaks and bleed any air from the system. Also, consider that clogged or faulty fuel injectors could be the reason, so clean or replace them as needed. Finally, check for any leaks that may cause seizure due to lack of lubrication. Fill to the correct oil level. Check for a clogged oil filter and replace it. Check the oil pump and lubrication system. Verify if the engine bearing clearance is within specifications. Follow oil and filter service instructions to prevent future occurrences.

Why does my Daedong 4A220 Engine have low power output?
- F
  Frank ThomasAug 27, 2025
  If your Daedong Engine has low power output, begin by checking and cleaning the injection nozzles, being careful not to damage the orifice. Replace the injection nozzles if they are not working properly after cleaning. Also, check and service the fuel system to ensure sufficient fuel flow. Inspect the valves for leakage, grinding them to correct if needed. Also, check the air cleaner, and clean or replace the element every 100 hours of operation. Low power output can also be caused by low compression, seizure of moving parts, incorrect fuel injection timing, improper valve clearance or fuel injection pump wear.

Why is my Daedong 4A220 emitting exhaust smoke?
- C
  Chad MaynardSep 2, 2025
  If your Daedong Engine is producing exhaust smoke or dark emissions, it could be due to several reasons. One potential cause is poor quality fuel, so drain and replace it with the proper fuel. Another reason might be a faulty fuel injector, which would need to be cleaned or replaced. Incomplete fuel combustion may also be the reason, so check the injection timing, injection pump, valve adjustment and typical causes of low compression. Make adjustment or repairs as needed.
