Changing your oil and fluids on a regular basis is very important. Over time, the fluids that lubricate and absorb heat break down and become less effective. If left unchecked, this could lead to excess amounts of heat and friction that could cause critical harm to your heavy-duty vehicle. For example, if you don’t change your engine oil, it will eventually break down and fail to lubricate your moving components properly. When this happens, the amount of heat produced by your engine is no longer manageable for your coolant system. This could lead to a wide array of serious issues like blown head gaskets, seized pistons, and more.
Components That Commonly Require Routine Oil or Fluid Changes
Your engine needs to be lubricated at all times in order to avoid catastrophic failure. Since diesel engines operate at extremely high temperatures, your engine oil will likely break down faster than in a regular passenger car. We highly recommend changing your engine oil in accordance with your manufacturer’s recommended serval intervals. Also, keep in mind that the lifespan of engine oil is generally reliant on the type of oil, whether it be regular, a blend, or synthetic.
Your engine also requires routine coolant flushes. Fortunately, coolant lasts a lot longer than engine oil, meaning it doesn’t need to be replaced nearly as often. Be sure to keep an eye on its quality, though. Is it boiling? Is the level dropping? Both are signs of coolant that needs to be changed.
Your transmission has a series of gears that are always moving and, as such, need to be lubricated at all times. Fortunately, transmission fluid doesn’t have to be changed nearly as often as engine oil, for your transmission produces significantly less heat.
Similar to your transmission, your differential also has gears that are moving at all times, and they, too, need constant lubrication. Fortunately, differential fluid doesn’t have to be changed nearly as often as engine oil, for your differential produces significantly less heat.
