Diesel motors have many benefits compared to gasoline, but they do have their downfalls, as with any mechanical item. They run in a different manner than gasoline internal combustion engines and utilize special parts. It is important that you provide your diesel with routine maintenance services to ensure that you do not suffer any of the following common diesel engine troubles.
If you do begin to experience any of these issues, or suspect something else is wrong with your vehicle, be sure to contact a professional diesel mechanic to get you back on the road.
Dying Lead Acid Batteries
Diesel engines have a high compression ratio, which places a greater load on the starter. This also creates a large draw of amperage from the battery, thus putting a lot of stress on the battery. Any amount of elongated engine cranking could cause the battery to die. It is important to ensure you have a strong connection at the battery.
Failed Glow Plugs
Diesel engines utilize glow plugs to create warm air which is then compressed with diesel fuel to generate the necessary force to run the engine. Glow plugs use a heating element that is very similar to those that are in toasters. If the heating element fails, which they can for various reasons, including age, it can be extremely difficult, if not impossible to start your diesel car or truck.
One of the most common causes of hard starting is the use of improper lubricant, or engine oil, inside the motor. It is important to use the correct type of oil, which may vary depending on the time of year. The summer months may call for a single weight oil while the winter may require the use of a multi-weight oil for proper engine function.
What does a decrease in diesel engine power mean?
If you’ve suffered a gradual or sudden loss of power from your diesel engine there is a good chance it is related to a fuel delivery issue. The fuel filter that is located within the fuel line between the fuel tank and the injectors is designed to remove impurities from the diesel fuel as well as absorb excess water, which is actually collected in the fuel filter bowl. This bowl needs to be regularly drained in order to avoid hard starting or power loss issues.
