How to Prepare Your Diesel Engine for Winter

November 12, 2023

Here are some tips on how to prepare your diesel engine for winter:

Change the oil and oil filter. Use a winter-weight oil that is specifically designed for diesel engines.
Replace the fuel filter. The fuel filter can become clogged with dirt and other contaminants over time, which can make it difficult for the engine to start in cold weather.
Check the battery. Make sure the battery is fully charged and that the terminals are clean and free of corrosion.
Add a fuel additive. There are a number of fuel additives on the market that claim to help diesel engines start and run more smoothly in cold weather.
Park your vehicle indoors. If possible, park your vehicle indoors overnight to protect it from the cold weather. If you cannot park your vehicle indoors, you can use a block heater to keep the engine warm.
Glow plugs. Make sure the glow plugs are working properly. Glow plugs help to preheat the engine before starting, which can make it easier to start in cold weather.
Ice and snow. Make sure to remove any ice and snow from the engine and vehicle before starting.
