The cooling system is one of the most important components in a well-functioning diesel engine. Properly maintaining the cooling system is crucial to ensuring the engine runs properly and lasts a long time. In fact, engine coolant maintenance is just as important as an oil change. Some diesel engine owners wonder if the cooling system in their vehicle operates the same way as a cooling system in a regular gas engine. Effectively, the systems operate the same way, only the coolant condition in a diesel engine may even be more important than in a gasoline engine.
One of the biggest reasons for neglect is probably that owners simply don’t understand how important it is to periodically check the coolant’s condition, even though this task is a necessary aspect of routine semi truck maintenance in Duncan, OK. To learn more about your diesel engine cooling system, read ahead.
Ask any diesel mechanic and they will tell you that the condition of the coolant in the engine means everything to longevity. Today’s antifreeze coolant not only protects from freezing in the winter months, but also helps protect diesel engines from common internal engine issues. Diesel engines operate using extremely high pressure and temperature. Engine coolant ensures a stable operating temperature, meaning that the high pressure of combustion will not damage vital engine components.
For diesel trucks using green antifreeze, the recommendation for coolant service is usually around two years or 30,000 miles. For diesel engines running extended-life coolant, service is around five years or 100,000 miles. To be on the safe side, have a mechanic check the antifreeze every six months during other routine semi truck maintenance in Duncan, OK.
Radiator cap, hoses and much more
While many people are familiar with engine coolant, and the importance of taking care of it, an often-overlooked component of the cooling system is the radiator cap. When performing an inspection, make sure the radiator cap is in good condition. Remember to also have the cap tested to make sure that the cooling system is maintaining the correct pressure. The cap is what maintains the cooling system’s pressure to prevent boil-over.
While conducting a visual inspection, also observe the condition of all hoses and hose clamps. Over time hoses, often made of rubber, can become dry and begin to crack. Hose clamps often rust or loosen with age. If a hose or hose clamp breaks, the engine coolant will drain out of the system and will require immediate attention from a mechanic.
Other important pieces of your cooling system are the thermostat, the water pump and the cooling fans. Thermostats often break with age—it is a good idea to prevent this by having your mechanic replace it at the recommended mileage. Water pumps should also get changed after they have hit a certain mileage marker. Finally, keep your engine running cool by ensuring that the cooling fan and radiator are free of debris and operating correctly.
Make sure that your mechanic takes special note of your cooling system during semi truck maintenance in Duncan, OK. Otherwise you may end up with a broken down vehicle or a damaged engine.
