How Do I Get My Diesel Engine to Start in The Cold?

Getting Your Diesel Engine to Start in The Cold

Before facing winter, those with cold diesel engine-powered machinery need to make sure these machines are properly maintained. By staying proactive, you can be prepared for the cold and make sure that your machinery starts as it would during any other season. From warming up your engine, to keeping a watch out for frozen fuel, here are some ways you can avoid start failure during the winter:

  • Warm Up the Engine Before Use: Allowing the engine to run for about five minutes before operating lets the machinery get ready for use. While this isn’t absolutely necessary, failing to do so will result in the engine working harder during use.
  • Heating Leads to Smooth Running: How you heat your machinery depends on what you really need to be warmed. Whether you need to heat the coolant in-stream, or ignite cold fuel, there are many options for heating the different parts of your engine.
  • Keep Diesel Exhaust Fluid from Freezing: Keeping exhaust fluid above 12 degrees Fahrenheit is important to keep it from freezing. If the fluid freezes, it can be more difficult to get the machinery up and running, and potentially result in engine start failure.
  • Watch Out for Any Frozen Fuel: Filtering and warming any frozen or gel-like fuel is crucial, because any fuel that is frozen can block up the flow to the injector pump.
  • Warm Location Storage: Keeping your machinery in a warm area not only allows it to warm up more quickly, but also keeps it away from natural elements like snow, rain and hail.
  • Keep a Full Fuel Tank: If a fuel tank is not full of fuel, it leaves space for condensation to build up—which can result in frozen or gelled fuel. By keeping a full tank, you can avoid this problem.
