What Temperature Should You Plug In A Diesel Truck?

Many of us in the Edmonton area rely on driving to get to work, bring our kids to school, and get food for our families during the winter months. While driving in light winter weather isn’t too bad, harsh winter weather puts a strain on engines. Our engines, like the majority of us, dislike the extreme cold. They work best in warmer weather, and while we can’t control the winter temperatures, we can use engine block heaters to keep our engines warm. Many of our Ford automobiles come equipped with engine block heaters to keep your engine warm throughout the chilly winter months. The cord to plug in your engine block heater is normally situated under the hood, as seen in the photographs below, and we’ve even drawn a box around it for your convenience.

What is an Engine Block Heater?

Let’s take a look at what an engine block heater is and what it does before we get into when you should plug it in. When you start your car, oil circulates through the engine block, lubricating all of the working parts. When we have harsh winter temperatures, such as -20° C or below, the oil thickens and becomes sticky. This makes it more difficult for the oil to travel through your engine, causing it to work more, consume more petrol, and emit more pollution. The engine block heater maintains a temperature that allows the oil to remain thin and flow freely through the engine block.

When to Plug in an Engine Block Heater

While the precise temperature at which you should consider plugging in your engine block heater varies, the main thing to know is that if it’s going to be severely cold overnight or early in the morning, you should probably plug in your vehicle. Newer vehicles can usually start at temperatures as low as -30° C, but if the block heater isn’t connected, the engine will be put under more strain. To be safe, plug in your engine block heater when the temperature drops to -15° C or lower. If you drive a diesel car, you may need to use the engine block heater to keep the temperature from falling too low.

How cold does it need to be to plug in a diesel truck?

When it comes to diesel trucks, how cold is too cold? At 15 degrees Fahrenheit (-9.5 degrees Celsius), the diesel fuel in your fuel tank will gel and you will have problems starting your engine. Your diesel vehicle will have troubles if the temperature drops below 15 degrees Fahrenheit / -9.5 degrees Celsius. The diesel won’t be frozen solid, but it won’t be liquid either. You must now rely on heating solutions such as block heaters and glow plugs, which are not available on all diesel engines.

There’s a lot of debate regarding what temperature is too cold for a diesel truck. On the internet, it is stated that the freezing point of diesel fuel is roughly -112 degrees Fahrenheit or -80 degrees Celsius. Now you believe you will never be in a region that gets that cold, so you should be fine. Wrong.

It is not necessary for the diesel in your fuel tank and fuel lines to be solidly frozen to cause you problems. When the temperature drops below 15 degrees Fahrenheit / – 9.5 degrees Celsius, the diesel fuel begins to change shape and becomes more like a gel. Consider a gel-like fuel that travels from the fuel tank to the engine. Traveling through the fuel lines would be difficult, and you would have difficulty starting your engine in the frigid winter.

Do you have to plug in diesel trucks in the winter?

Cold has the same vengeance on mechanical objects as it has on organic ones. When winter arrives, efforts must be taken to safeguard diesel engines, new oil burners, and especially older oil burners with glow plugs, in order to maintain powerplants and ensure rigs remain reliable until climates warm up.

Can I leave my diesel plugged in all night?

Is it okay for me to leave my truck plugged in all night? After three hours, the temperature reaches its highest point ever. Any additional expense is simply a waste of money. If you leave it plugged in all year (winter, summer, or in between), the engine will not be destroyed, but you will have to pay $100 every month to keep it hooked in.

Can you start a diesel with the block heater plugged in?

Having a block heater during the harsh winter months offers numerous advantages. In extreme cold temperatures, your engine will start significantly easier. So you’re set to go in the morning. It will not harm your automobile to have your block heater plugged in and start it at the same time.

Is it bad to start a diesel in the cold?

In cold weather, diesel engines are more difficult to start because they rely on high temperatures caused by compression to ignite the injected fuel. In fact, starting a diesel engine at 0°F (-17°C) is five times more difficult than starting one at 80°F (26°C).

How do you start a diesel truck in cold weather?

Gelled gasoline and electrical failure are the two most common reasons why people have problems with cold diesel engines. Cold diesel engine-powered apparatus must therefore be adequately maintained before being exposed to freezing temperatures. With that in mind, here are six recommendations for starting a diesel in cold weather and keeping your equipment in good working order over time.

Do Not Underestimate Warm-Up Time

It’s critical to allow your cold diesel engine to warm up. Allow your equipment to warm up for at least five minutes before using it; this will allow the hydraulic oil to warm up. If you don’t, the engine will have to work more than it needs to.

Consider Heating Options

When it comes to heating your gear and keeping it working properly, you have various alternatives.

  • An electric block heater heats the coolant in the system, which warms the engine block and oil in the crankcase. This makes it easier for the engine to flip over.
  • A diesel-fueled coolant heater can be used to warm up your engine in areas where power is not commonly available.
  • Glow Plugs: These can aid in the ignition of cold gasoline and also heat the fuel-air combination inside a large engine.
  • A Battery Tender: As the temperature drops, the cranking amperage of equipment batteries decreases. While machinery is susceptible to this type of failure, a battery tender will continue to function as long as it is fully charged. Battery cables should be checked before winter for owners of cold-diesel equipment. A battery’s ability to start machinery is harmed by bad connections.

Keep Your Diesel Exhaust Fluid Thawed

If you plan to add DEF to your apparatus later, keep it above 12 degrees Fahrenheit to prevent it from freezing. Although freezing does not reduce the uptime of your equipment, keeping DEF on hand ensures that it is ready to use when needed.

Address Frozen Fuel

During the winter, diesel fuel creating wax crystals is a more usual impediment to machinery starting smoothly. Fuel filters will become clogged as a result of the contaminated fuel, and the engine will not start. Using winter-blended diesel fuel, which lowers the temperature at which these crystals form, is one technique to prevent crystals from forming in the gasoline.

According to the University of Tennessee Agricultural Extension Service, if your fuel has frozen or gelled together, you should change the fuel filter and reheat the fuel before starting the engine. This prevents the frozen fuel from obstructing the flow of fuel from the tank to the injector pump.

Keep Your Engine in a Warm Area

If at all possible, keep your diesel engine in a warm place away from the elements like sleet and snow. Keeping the engine in a warmer environment, even if it’s only a few degrees warmer, can help it warm up faster.

Make Sure Your Fuel Tank is Full

Condensation in a fuel tank can eventually freeze, causing difficulties similar to gelled fuel. In the winter, keep your fuel tank as full as possible to prevent condensation from forming. A winter diesel fuel additive may also help to prevent your gasoline from freezing up.

How long should I let my diesel truck warm up in winter?

If the temperature is below zero degrees Fahrenheit, you should allow your engine to warm up for up to seven minutes. Warm-up time should be three to five minutes if the temperature is between zero and fifty degrees. Warming up to above fifty degrees takes only one or two minutes.

How often should you drive a diesel truck?

The recommended service interval for most diesel vehicles is every 3,000 miles or 6 months, whichever comes first. However, depending on the type and model of your automobile, as well as how much you drive, this service frequency might vary dramatically. Short-distance driving on a frequent basis can cause oil in diesel cars to quickly acquire sludge or other impurities. It might be difficult to know when your car needs to be serviced.

So how often should a diesel car be serviced? Here are five key signs that a service is due on your diesel car.

  • It’s difficult to get started. Low compression or a fuel delivery issue might cause difficult or delayed starting. When you start a diesel engine, it’s common for it to crank a little, with a typical crank time of 3 to 5 seconds. Have your diesel car checked out as soon as possible if crank times are particularly long if the engine is exceedingly difficult to start.
  • Smoke is billowing. Keep an eye out for smoke coming from the exhaust pipe that has an unpleasant odor. You should be on the lookout for three hues of smoke: black, blue, and white. These emissions could indicate a defective injector, injector pump, clogged air filter, or other engine or sub-system issue.
  • Inability to perform. This could be a sign of low fuel pressure, clogged fuel filters, or something more serious. If your diesel vehicle is underperforming, bring it in to get dynamometer checked to discover the actual power at the wheels and compare it to what it should be.
  • Knocking. Knocking can be an indicator of the engine’s age, but it doesn’t always mean there’s a problem. However, in the worst-case scenario, it could suggest fuel contamination or malfunctioning diesel injectors, affecting compression balance and lowering performance.
  • Running in the woods. This is a common symptom of a faulty glow plug or a faulty fuel injection system, resulting in difficult starting and rough running until the engine reaches operating temperature.

Remember: Having your diesel automobiles inspected and serviced on a regular basis is the best way to guarantee they are in good working order.
