Test the battery
Chilly weather can take a toll on your truck’s battery, according to DrivingLine’s Mike McGlothlin. Test it to make sure it has enough life in it to survive through the winter. If it’s about to die, it’s a good idea to replace it with a new one to help prevent breakdowns.
Use a block heater
Many diesel trucks come with a built-in block heater to help keep the engine block warm on frigid winter nights when the temperature dips below zero. If your truck has this feature, tap into it. If not, consider purchasing a block heater accessory.
Try an anti-gel fuel additive
Depending on how cold your region gets in winter, you might want to consider using an anti-gel fuel additive. This product will help prevent the fuel from gelling up once it reaches its “cloud point.” This cloud point is the point when wax crystals start to form in diesel fuel. Most fuels reach the cloud point when the temperature falls in the range of -18 to 20 degrees Fahrenheit, according to McGlothlin.
Switch to a lighter-weight oil
Another thing to consider is swapping out your truck’s motor oil for one with a lighter weight. This will boost the oil’s ability to flow when the weather turns wintry. Consult your owner’s manual, though, to verify that the new oil you use is compatible with your particular model.
Replace the fuel filter
Get a new fuel filter for your truck, if it’s been a while since you replaced this part. New fuel filters have clear cartridges that will help reduce the likelihood that the fuel will gel due to cold temperatures. Some trucks have two fuel filters, in which case, make sure to replace both.
You should install a new fuel filter approximately every 10-15K miles according to Xtreme Diesel Performance. Though, if you regularly use your truck for heavy-duty towing jobs, you should do it more frequently.
