How to Keep Your Diesel Engine Running Smoothly in Cold Weather

Cold temperatures can be tough on diesel engines, just like any other piece of equipment. That’s why it’s essential to follow proper cold weather diesel engine care practices. At Young & Sons, we understand the challenges that cold weather brings. Whether you need winter-ready parts, engine repairs, or a complete rebuild, we’re here to help keep your diesel engine in top shape during the toughest months.

Winter weather thickens oil, slows fuel combustion, and can even cause components to freeze. From there, you’re looking at hard starts or complete failure. But by taking proactive steps, you can prevent diesel engine freezing and ensure your engine runs reliably throughout the winter.

Use the Right Fuel and Additives

One of the biggest factors in cold weather diesel engine care is making sure you’re using the correct fuel blend. In freezing temperatures, untreated diesel fuel can gel, which clogs fuel lines and filters. Switching to a winter-grade diesel blend with anti-gelling properties can help keep your engine running smoothly.

You can also use cold-weather fuel additives to help improve fuel flow and prevent wax buildup in the fuel system. These additives lower the temperature at which diesel gels. They also enhance fuel combustion, so you’re putting less strain on your engine. Just follow the manufacturer’s recommendations for fuel and additives and you should be good to go!

Maintain Your Battery and Glow Plugs

Cold weather significantly reduces battery efficiency, which can make it harder to start your diesel engine. Checking your battery’s charge, ensuring clean terminals, and replacing an old or weak battery before winter hits are all good steps to follow in cold weather diesel engine care. 

Glow plugs and intake heaters play a crucial role in starting a diesel engine in the cold too. If your engine struggles to start, faulty glow plugs could be the problem. Be sure to inspect and replace worn glow plugs before winter.

Prevent Freezing with Proper Maintenance and Heating Solutions

To prevent diesel engine freezing, routine maintenance and heating solutions are essential. Regularly checking and replacing fuel and air filters means that your engine will get clean, efficient combustion. Keeping oil at the right viscosity is also critical, because thick, cold oil can cause excessive engine strain. Switching to a winter-grade oil helps ensure proper lubrication even in freezing temperatures.

Engine block heaters, oil pan heaters, and fuel line heaters can make a significant difference in preventing freeze-related issues, as well. Parking in a garage or using an insulated engine cover can also help retain heat and further protect your diesel engine from extreme temperatures.
