The most obvious cause of engine overheating is if there is any type of issue with the engine coolant. Another reason that your diesel’s coolant level is low is that air pockets or bubbles may have gotten into the radiator or reservoir causing a restriction of fluid flow.
Can bad fuel injectors cause overheating?
If the fuel injector is clogged, the fuel supply will be irregular too. As the engine misfires, the engine can quickly overheat and pre-ignite the fuel mixture. A damaged fuel injector will not only causes issues with driving, but the effects will persist even as the engine idles.
